I just purchased a 2003 E500 Sport. The owners manual does not stated the Oil weight or viscosity. It does state to use Mobil 1 synthetic, but not the weight, e.g., 0w-30, 10w-30, 15w-50, etc. Can any tell me what weight to use? I do live in the south where the coldest temp. would be 30 to 40 deg's. I will use the Mobil 1 or Redline synthetic oil.... any comments?

I run Mobil 1 15W and have encountered no problems in my 98' E430. You can also run AMSOIL of the same weight if you prefer.

Mobil 1 has a 0w-40 that is made specifically for european cars. I use it in my C 230 Komp and I live in a hot climate. I also use it in my girlfriends Golf 1.8T. Her Golf is turbcharged and it works perfect for both cars. I usually buy it at Autozone for 4 something a quart. Redline is a good product probably and does use a beefier basestock of polyol ester but is expensive and hard to get in my opinion. Amsoil just doesn't make sense to me. If I am not mistaken, they use the same type of basestock as Mobil 1, which is PAO(polyalhaolefin), but you have to put up with the inconvenience of the availabilty. Castrol synthetics are a joke. They are the ones who just recently had the court case where the outcome was to allow group III mineral basestocks to be considered synthetics. This is a crime in my opinion.

If you just bought a E500 2003 model, the services should be included in your purchase for 50,000 miles, isn't it? Why worry about doing the oil yourself and taking the chance to void the warrantee? You can always ask your service adviser from where you bought your car and for service. Oil grade depends on where you locate and how you drive, I guess.

Why would you be on a enthusiast's forum with that outlook. Just go ask your service advisor.

Anyone have any real independent evidence of the advantages of Mobil One, Amsoil, and Redline synthetics over one another?

I cannot find any sources of a reputable, named testing center to vouch for the integrity of any of these synthetic oils.

In my opinion, the difference between AMSOIL and Mobil One really boils down to convenience and price. Mobil One sells for almost a $1 per quart cheaper (even with AMSOIL preferred customer status) and ~$2.70 cheaper than AMSOIL at retail prices. AMSOIL looks technically better but I highly doubt that anyone who isn't into seriously racing or running fleets will actually experience a statistically significant difference in AMSOIL vs. Mobil One synthetics.

Everyone has to do regular oil changes anyways so the extended drain interval marketing gimmick makes no sense and may in fact be more dangerous to your vehicle's engine or transmission. I say to get what makes sense, based on availability and cost and to look at the bottom line, statistically significant differences. Either Mobile One or AMSOIL should be good for the average consumer. One fundamental problem with AMSOIL is that they don't make it available at the retail level at national stores and they price higher. Why this is remains a mystery but pushes on business practice without questioning technical merits. Still Mobil One is so much easier to obtain and cheaper, making it an easy sell. You would think if AMSOIL was serious about their synthetics that they would make their product as easily available as Mobil One. Nobody could really care less if AMSOIL is the first in synthetics. It all boils down to common sense and staying away from gimmick advertisement from either company. AMSOIL is great if you're rich and can find it easily. Otherwise, don't feel bad about other synthetics that come measurably close.

Still, where's the true name-recognized independent testing? Who is really there to verify any of these claims? Average Joe simply doesn't cut it.

My newest car is a 1995, so I don't know what the recommended oil change intervals are for the newer Mercedes models, but if you do some research, you'll find that the whole "change your oil every 3,000 miles" is largely an American marketing phenomenon.

I was talking to some friends that recently came back from being stationed in Germany, and they said that with synthetic oils, most people there change their oil about once a year, somewhere between 10,000 and 15,000 miles.

With modern synthetic oils and factory-applied cylinder bore coatings like "Nikasil", engine wear really isn't as much of a concern as it used to be. I've disassembled 100,000-mile engines that still had the factory cross-hatch honing marks on the bores!

as a AUTOMOTIVE PERFECTIONIST, there is only one way to go, for MY car, and thats with the best money can buy.....

on average, Mobil One creates MORE wear, during the ASTM 4 Ball Wear Test, than a CONVENTIONAL Petro Oil....of the same weight........

now, for most people, who SIMPLY DONT CARE.....all this doesnt matter....

then it will unfortunately come down to availability, and pricing....for me however, the extra wait, and 2 dollars per quart, are MORE than worth it....

i go for 12 k miles, on my diesel, between oil changes, using Amsoil Series 3000 Heavy Duty Diesel 5w-30 (their best diesel oil.......their best gas oil, Series 2000, is good AND GUARANTEED, to have 1 year, 35k mile drains...) (ATF 3 times manufacturer interval)

upon switching to ALL amsoil fluids....i experienced about 100 miles per tank more.............highway..

city-wise, i can accelerate like HELL.....which unfortunately sucks diesel like mad...which is why i havent much change here, i cant keep my foot off, at the lights.....[:D]

as far as base-stocks go, only 2 PEOPLE in the WORLD know the formulation, for the Polyalphaolefin Molecule, used as the base for all Amsoil products....this is because it's PROPRIETARY, and thus other companies DONT use it, as they dont know what it is....

Amsoil took 7 YEARS of initial development, by the top chemists in the country, before marketing the first 100 percent synthetic motor oil, in 1973, with drain intervals of 25k miles...

that year, MOBIL OIL co, decided it needed to find a way to put down this new competitor....

they started 60 percent synthetic Mobil One, as a way to counter this...also offering 25k mile drains...

after 2 years of bad seals, and blown motors, and LAWSUITS (which Amsoil never has had), they reduced the drain interval to 3 k miles.......and have had it there ever since, until they're "NEW" and "REVOLUTIONARY" 15 k drain interval, that they now spend 100's of millions advertising....

still only second best....and twice the wear and half the drain interval as well....Hmmmmm, which one should I use...?


So, by now, ur all mad, and wanting to defend the old beliefs, since you have always heard them, and want to say "Hey, dont say that, it CANT be true.....caus I didnt see it on TV..." and want to get me banned, as an "advertiser".......well, what do u think u are doing for Mobil One, telling people to use it? free advertising....

Besides, i speak ONLY the truth, and dont even work with their company at all.....i am a delivery driver, for Papa John's Pizza, right now i'm on my break, in between lunch, and evening shifts.......I use their products, to ENSURE that i get the best mileage, and most protection, for all the running-starts i do, and stop and go, and idling alot.....my oil press gauge Never wavers......and i get to save money, by only changing my oil, every 12 k............

so, that was long, but i'v spoken my piece.....if anyone had a question, i would be happy to help answer it for u, or give u steer in the direction of the info u may want....however, dont expect me to respond to criticism's or claims that i'm lying, or wanna say that the seals will leak (they actually swell using amsoil, stopping leaks), or that the oil is "too thin" (crap, amsoil has a HIGHER film strength than any other oil, petro or not)....as i really dont have the time to waste......take this as u will, i can only say that it is the TRUTH, and nothing more........have a nice day....! [:)]



EDIT: oh yeah, so all bases are covered, i will say this "Mobil One is a GREAT product.....compared to many...i would much rather see u fill that in, than "Wal-Mart Supertech"...".........its just, that its not PERFECTION............

One fundamental problem with AMSOIL is that they don't make it available at the retail level at national stores and they price higher. Why this is remains a mystery....
1. Mobil OIL Co. spends 100's of millions a year on advertising, Amsoil DOESNT......

"the product sells itself, based on that its the best....if someone was worried enough about their car/truck, they will get our product..."

-thats the policy, by company founder/owner Col. Al Amatuzio (USAF Ret.)

2. For the same reason, it is not sold at "autozone" or "Wal-Mart", caus TRUE car enthusiasts know that these stores are useless, except to buy brake spray, and car washing soap.....

as far as price goes, its just like MB versus Kia....u GET what u PAY for...


If u are into Motocross, or GP racing, or snowmobile racing,or 4 wheeling, or champ boats series, or NHRA drag racing, do a search, on these sports, and include "amsoil" in the search parameter....

u will be SHOCKED to see how big Amsoil really is.....

A very good source for private enthusiasts testing various oils and debating some wild claims is http://www.tdiclub.com

Most of the Amsoil hype is either negated or ignored on this very reasonable site. They find no evidence of synthetic oil deterioration well past the 10,000 mile drain intervals, including Castrol synthetics. There is even evidence that changing the oil sooner may increase wear, with theories about the oil components needing to be heated up or that they stir up particulates normally found after an oil change.

At any rate, following the manufacturer's recommendations seems the best way to avoid wasting money and decreasing the environmental impact of waste oil. Some even suggest paying attention to other maintenance items such as filters would go a long way toward preserving engine life.

I signed up for the AMSOIL preferred customer list. I really did not do my research and have just recently went through some of the material, after several hundred dollars worth of purchases. (Too much for my pocket book, right now. As I am broke after today's big purchase).

I learned the answer to one of my questions, the one about why AMSOIL (and most likely Redline) are not sold through retail chains. The real reason is pyramid marketing. The more I learned about AMSOIL retailers, preferred customers, and dealers, the more it began to have similarities to such a marketing scheme. After actually reading their own literature, it is very clear that this is the style in which the product is introduced to consumers. The dealer who sells to you benefits from point zero onwards on every purchase you make. If you then become a dealer, you then earn credits and a commission based on what your "customers" (preferred or not) make. The $10-30 commission to enter into this alliance serves as a membership into this plan. The persons more at the top of the chain make money on purchases of everyone down the chain. Indeed, the original customer winds up being a big source of revenue for people higher on the food chain. Pretty soon everything from clothing to longevity vitamin pills, coffee mugs, sports jackets, and toys are being hocked through preferred customer catalogs or websites, all of which are in some way affiliated with AMSOIL.

I am not a fan of pyramid schemes and learned my lesson with another product by the name of Amway many years ago. It does seem compellingly interesting that Amway and Amsoil both share the same prefix.

As a result, I have to question everything about the product and really do invite legitimate name-recognized testing of these synthetic oils. I don't have money to burn, as I barely make it on what I have. I only write to learn more and uncover details and truth about not just AMSOIL, but also Mobil One, Castrol, Pennzoil, Redline, Lucas and every other automobile parts/commodities supplier out there. I would warn others to do the same, until any and all claims made by any company as fact can be proven.


The best advice may be to adhere closely to manufacturer specs on everything for your Mercedes unless definitive, independent evidence can be produced to statistically support any and all marketing claims made by other equipment manufacturers.

I guess, we're all talking about our cars, none of which, no matter how old are inexpensive. It is consequently important to pay respect that is due to the car, its manufacturer, and recommendations, unless it can be proven otherwise.

I just want to add that if there is truth to the literature and claims, then it seems like a win–win situation for all associated with AMSOIL, as you could potentially be getting a good product and also earning for recommending it. Hopefully the truth is indeed true.

I only wish I knew for sure with some real science behind it and the other products, which are not as open.

I asked a friend of mine who is a chemist if he could do the double-blind hplc gas chromatography studies and other testing as necessary to prove the ingredients and quality of each oil. He's looking into it.


However, there has to be a real independent testing lab that has already done this and can tell consumers the facts about each and all the major synthetic brands and the ones to use.

Hi GTB.

"However, there has to be a real independent testing lab that has already done this and can tell consumers the facts about each and all the major synthetic brands and the ones to use."

Any lab capable of conducting such tests will be glad to sell you the information you need, exept the results which are off limits due to arrangements. And that's where the information you want lies.

But the answers you get, does not necessarily give you the information you need to make even an educated guess. The parameters are so very many.

It is the guys who makes the engines that really know. That is where you want to collect info on what oil, and what not.

If you go to the oil guys, they will for sure want to pour honey in your ear. That's what they're paid to do. They might know more than the engine guys about oil, but they rely on the same guys info to determin what oil you should use. U C ?

Last time I responded to an oil related post, I was accused of being either Frazier or Niles in a wine discussion, so I won't elaborate much on it here. But if you like, you can PM me.

I could say a wee bit, though. The Majors, Exxon-Mobil, Shell, etc., produce predictable good quality. Every one. The specialists, like some of the ones mentioned earlier here, does not necessarily. Some do, some don't.

Read the "Bob's the Oil Guy" Web site and you will know more about oil than you ever wanted to...

http://www.bobistheoilguy.com/

I read on their site that DMB is doing away with the FSS in the '06's. Is this true? It would be too bad, it's been an excellent tool for managing the service interval.

Hi all.

"Read the "Bob's the Oil Guy" Web site and you will know more about oil than you ever wanted to..."

I agree with what you say here, but you will still have no clue as to how to determin if an unapproved oil will do in your car or not. And he does sell Schaeffer oil.

The pure weight of all the data available from the oil industry is bone-crushing, so any ordinary person would die of boredom long before they had the slightest grip. A better method is to ask the people who actually tests different oils againts what they actually design and build. They have done all the reading and fickling for you. And they want to push cars, not oil.

MB issues oil sheets. It's the only tool you need. And if you should be in such a place where an approved oil can not be obtained, you can call them and ask if this or that oil could be used. As the thread starter points out, there is seldom an actual viscosity value stated in the owners manual. The reason is the size and diversity of the planet Earth. People in Siberia and Equador need different values, that's really up to you. I would ask my mechanic.

I think Wolfgang sums it up pretty good.

http://www.whnet.com/4x4/oil.html


When I read major oil companies specification charts, it's obvious to me that lawyers and other top brass review and sober up the information to conform to a certain "branch standard of truth". They have long ago learned to respect customers trusting them with their dear machinery. That's why they will most likely not exaggerate but rather hold back on actual promises. In the slogans and commercials though, they will gibberish as good as anyone.

Other oil delivering companies may not be as careful. And oil suppliers attacking other suppliers is always a bad sign. When I read GotTheBenz posts, I read the amsoil post again, a little closer. I found this.

"on average, Mobil One creates MORE wear, during the ASTM 4 Ball Wear Test, than a CONVENTIONAL Petro Oil....of the same weight........"

"EDIT: oh yeah, so all bases are covered, i will say this "Mobil One is a GREAT product.....compared to many...i would much rather see u fill that in, than "Wal-Mart Supertech"...".........its just, that its not PERFECTION............"

Those words stand for themselves. But I have seen some rather respectable members here recommend it to others on this forum, it might very well be a good oil. I have never seen the stuff, so I have no clue concerning Amsoil.

I think a lot of the "better oil" concept is a hype. If you tell a guy that you have added a secret goverment formula additive that does this and that, so and so, chances are good he will confirm the effects. That's how we humans work.

An engine, on the other hand will pay no attention to a hype.

Great points you make.

Small correction. AMSOIL300CDT made those specific remarks.

I did put in the AMSOIL ATF into my transmission and power steering. I also have been driving with AMSOIL 0W30 oil for 3 weeks now. My only remarks right now is that there seems to be an improvement in overall performance and it appears to be running cleaner through visual inspections; however, this was my first oil change for the crankcase and the transmission + power steering for this car, specifically. The improvements appear to be better but this may be simply due to changing out the old oil (as I had no knowledge of the prior condition of the vehicle and how the prior owner maintained this car but it was pretty bad when I got it) or it may actually be due to the synthetic brand of oil. There really is no way to know for sure, scientifically, as I cannot run two independent experiments with two different variables simultaneously.

In either case, the truth can only come from as you say people who test engines with oil brands on the market. I agree that the big labels generally have better gas and oil than smaller labels. I only wish the public could get more accurate specifications and expert testimonials (trained engineers and mechanics are best) than from consumers and John Doe's or those affiliated with any oil label.

P.S. I will add that my SEC seems to be accelerating a lot better and shifting through gears smoother ---improvements for which I am pleased; however, I really cannot say that this is due to the brand specifically. It is too difficult to objectively make that claim of one brand over another.

"Small correction. AMSOIL300CDT made those specific remarks."

Quite right. Sorry for not quoting that more clearly.

To AMSOILCDT.

I'm not mad, and I would never want you banned. On the contrary, I like reading your posts.[:)]

Over here too we have people knocking on our virtual doors, trying to sell better or more econimical oils and additives. Amsoil seems to ship only to the US and Canada. But we have others. I don't think we have any, what's it called, direct marketing oil schemes here though.

Whenever a producer tries to narrow the outlet channels for their products, a bell is always ringing in my ears. Normally, any producer will broaden the channels as much as decently possible, to sell as much as possible. So why would anyone with a superior product not want to spread out it's retail points? The reason can only be to steer and gear the profits.

The products in such schemes may have high quality and usefullness. Amsoil may be the very best you can get. When someone says something sells itself, they're always wrong. They expect you to sell it.

you'll be safe using Mobil 1 0w-40. It is on Mercedes 229.5 approved list and is available at your local Wal-Mart-a win-win situation. Personally I don't care much for Amsludge. Might be an OK product but their marketing and sales modality sends up a red flag-but heck, it's a free country!

Agreed, I think Amsoil should open up their product sales to any customer at retail outlets. It is like hell to try to order and obtain their product. You have to wait for the dealer to deliver it to you and you wind up wasting many hours and days doing so, when you can simply go down the block and pick up alternative products. It is really bad marketing to sell it the way they do. Even AMSOIL300CDT has a hard time getting a hold of it. For me it is a huge waste of precious of time! but I have been willing to make this trade-off to try it and see for myself, at least for now.

Plus, when I looked at the several catalogs they mailed me and saw longevity vitamin pills, coffee mugs, and miscellaneous (toys, clothing, ...) and the credit/points/cash earned for dealing their products through sponsorships and websites (this is why there are so many websites promoting it), it sent up really big warning lights. It is just like AMWAY. If anything it detracted from the authenticity of any claims they made about their oil.

Everyone knows that longevity vitamin pills are non-science and scams. To associate their product with something like that really pushes it down and makes one wary.

If it indeed is better it is really stupid to market it the way they do and can only point to boosting profits or creating a pyramid structure.

I am just hopeful that what I paid for actually works well, because, for me, it cost a huge fortune and actually set me back financially, on expenses I never would have taken. This does not even include the huge loss in time (aka, a week to simply do an oil change X 2!!#@$%*(#!!) If this translates into something great for the car over a long term, then it will pay off; otherwise, I'll be the first person to be downplaying their products and I'll do it real hard, too. It's a been an overburdening cost to me so far.

However, to be fair, Mobil One is actually slightly more expensive for ATF and Gear Oil, but cheaper when it comes to engine oil. I also know AMSOIL300CDT doesn't have much $ to burn either, but believes in Amsoil strongly. I just hope he is not being taken for a ride as well, because there really is no way to scientifically learn the truth about the alternatives through independent labs (the clincher! and basis for huge marketing profits by any and all companies [aka, keep the masses ignorant and profit off them in the process]).

I am curious. What specialty brand of products are available in Europe (Norway)?
