Question Engine Additives????????????

I called the parts department at my local Benz dealer and requested all parts that I would need for the B service. Along with all of the normal filters etc, the guy gives me a can of BG 44k and another can of BG MOA. The owner’s manual says (No engine additives). What is the deal?

That's because there is a difference in opinion between the folks in Stuttgart and the local Stealerships.
Stuttgart says Transmission is sealed and NEVER needs an Oil Change.
Local reality is you need to change it every 2-3 years.

Stuttgart says not to add engine additives.
Local reality is after market manufacturers make some great additives that benefit our $$ wallet, engine performance, physical appearance.


Stuttgart says not to add Fuel Additives
Local Reality is Fuel is contaminated with dirt, debris, water and condensation.


There sure is a lot of stuff that comes from that office building in Stuttgart
YOU personally have to decide where to break ranks.

When I lived in Germany you would see countless Germans adding stuff to the engine oil, fuel, after market wheels, polishes, interiors etc.
All without the benefit of Stuttgarts Endorsement

I will continue to use my Sea Foam, Techron etc every few months.
I will continue to use Mobil 1/Amsoil AND my Lucas products

Your local dealer was trying to push a product on you because it makes them a huge profit. You can get the same stuff at Pep Boys/Autozone much cheaper.

Cool

Thanks for the info, I just don't want to hurt the car by adding bad additives.

Hey, acarter.

You'll actually hear lots of stuff both ways, and if you do a search you'll find lots more.

From hanging on a couple of MBZ forums I think the consensus is more to *avoid* most additives, particularly oil additives. (And honestly, as finicky as MBZ transmissions can be, I don't think I'd put anything in there other than MBZ's specified fluid.) Pretty much everything either way is anecdotal (along the lines of hey I ran slick 50 and my engine seized or I ran slick 50 and got better mileage) but with all of the design engineering into the engine internals and oil specifications, I have to think if there was something that was beneficial (and not merely unharmful) that MBZ would embrace it. Lucas makes some fine products, I can't imagine you'd actually hurt the engine using them, but the question is whether you are getting any return on your investment, or are you just adding to the expense of what you drain from your crankcase every so often?

One place I do include additives is the gas tank, since no manufacturer has any control over the hundreds of thousands of places you can buy gas and the quality controls any of those places have in delivering the end product. Not to mention that good fuel additives also disperse moisture, which can be a real killjoy. However, at least for my Benz, that's it.

In the end I'll repeat my generic mantra: one of the beautiful things about car ownership is getting to decide how (or even if) you will maintain your car, so do what you decide is right and let others do the same.

Take care and enjoy the ride,
Greg

Around 2002 the Gov and the oil folks [one of my favorite teams] got together to discuss additives in motor oil and their additives. Two of the additives that were removed from most motor oils were ZDDP and MOLY, both PRIMARY Anti-Wear Additives.. These LUBRICANTS have a zinc content that can, in the long term damage some manufacturers cat converters.

So what we have now is reformulated oil that lacks some of the basic lubricants that Stuttgart and Detriot and everyone else expected to be in the oil up until 4 years ago.

EDIT:

The best way to get motor oils that still contain the Anti Wear Additives that were expected when most of our Benz engines were designed is to either get some of the HD Diesel Motor Oil [which works very well in our cars], botique oils or buy an additive and put it in yourself when oil is changed.

I read something on one of these forums that bears repeating. In his opinion, the reason M-B advises against using all additives is to hopefully prevent us from adding substances "willy nilly" to our cars. I think we might all agree that there is a lot of garbage out there.

My preferred Chrysler-Plymouth technician thinks BG 44K is great stuff. He told me he ran a can through some engine and then took it apart - he said that baby was clean! I have used some in my Plymouth and Toyota, but now that I use only Chevron Supreme gas in all my cars and also add their Techron Concentrate every 3000 miles, I'm sticking to that plan.

Lastly, when I had my last B service on my former Benz, I noticed on the invoice that the dealer added something to the fuel. I asked the service manager and he said it was "probably Techron".

Hey, MM. I guess that's my point exactly, is that all of this is conjecture and speculation and opinion. There's no hard facts either way, MBZ's internals are known to go to several hundred thousand miles without additives, so...

It is NOT just conjecture and speculation. Oil companies [like Mobil] spend 10s of Millions in R&D burning in engines with different compounds of oil to determine wear and tear issues.

The historical "hundreds of thousands of miles" for Benz motors went out the window when all of the formulae changed in 2002 as ZDDP and MOLY were removed from engine oil. Now, dino and synthetic oil, without the PRIMARY Anti Wear Additives are the "new norm".

Google research from FLEET operators about the differences that they have seen with the new formulae and with the use of additives. These are companies that clock 3-5 million miles a year on well maintained motors and annoyingly detailed record keeping.

Benz does not suggest any additives purely on a liability position. They do not want to be responsible if you put something in your motor that may or may not add a variable to their motor. Much like, in the not oo distant past Mercedes "ONLY" recommended Michelin tires. Was that because only Michelin tires would work on the cars?

mcbear: gotta ask? Those of us with newer engines with extended service intervals per the FSS are specifically told by MB to use synthetic oil. Are you aware of any anti-wear additives that might be helpful to us?

It's because BG pays the dealership mechanics to do this.

They have a prize catalog and everything.
