Shell Rotella T Oil - Safe to use?

I know everyone has there preference about oil bra d.

My question or concern is more general.

I was looking at the Shell Rotella T Oil 15W/40 (non-synthetic)

All it says is for diesel. Nowhere does it say anything about use for gasoline vehicles. I was also looking at the Castrol GTX Oil. Same thing. Does not say anything about use in gasoline engines.

As I have a gasoline engine (3.0 L), is it safe to use this Shell Rotella T Oil even though it says nothing about use in gasoline engines?

Does anyone here use this Shell Rotella Oil (non-synthetic) in their gas engines? Any issues?

What I don't understand is if it is okay to use in gasoline engines, why don't they write it. I see the API CJ-4 on the logo, but I don't know what is acceptable for our 300E's as it is not in our owner's manual. Thanks

Thanks for the replies.

I see the "SM" designation.

This Shell Rotella Oil says it meets mb approval 228.31.

Is the correct approval for our 103 gas engines 229.1?

I just seen this spec sheet from MB for 229.1 and Shell Rotella is not listed (but the Castrol GTX is). The sheet was updated on 08/01/2013.

MB 229.1 - Multigrade engine oils (Specification 229.1) - Mercedes-Benz Specifications for Operating Fluids

So now I am wondering if we should be using this Shell Rotella Oil (if 229.1 is correct for us). And I don't see the chevron oil listed either.

The Rotella T6 synth is the way to go. High levels of ZDDP and gas/diesel approved. Don't use oil based on the MB approval, the oil requirements pre 1997 MB are totally different than post. Bobstheoilguy.com is a good resource.

yeah you really want to use the lightest oil you can. The difference between 5w40 and 15w40 is nothing in summer but a lot in winter. Its also better not to switch oils alot because the additives packages can interfere.

I went to the MB dealer to get some parts and the parts guy working there (who happens to drive a 1994 E320) also said the Shell Rotella is fine. He also said they fill our cars with 15w40 of Quaker State, which is the same brand that they used years before when I used to take it to the dealer.

Yet according to MB, Quaker State is not even listed here as an approved oil on their website:
MB 229.1 - Multigrade engine oils (Specification 229.1) - Mercedes-Benz Specifications for Operating Fluids

What good is having these approved lists if they don't update them!

The approval list is worthless. Just because an oil doesn't show up on that list doesn't mean the oil is would not pass the test. Also keep in mind that these lists have more to do with extended oil change intervals and fuel economy than the quality of the oil.

It doesn't have to be about updating them -- more to do with meeting the standards and I am sure, some level of cost that oil manufactures simply do not want to pay to get a mark of approval from MB.

Either way, stick with whats tried and true. You won't find one person on here who has said 15-40 diesel oil shortened their lifespan, or caused X issue. Its been tested with time. Not so with synthetic...(yet).

Looks like 229.3 or 229.5 and SJ or SL "IF" one of those
spec oils is not available.

Mobil 1 0W40 Synthetic

When we purchased our 95 E320 wagon over two years ago, I called our local Benz dealer for a recommendation on oil since this was our first Mercedes. The dealer, Mercedes-Benz of Rochester, only carries Mobil 1 0W40 full synthetic and that is what goes in every gasoline car that passes through their service center. Along with the Jetta we own, which I've run synthetic in for 5 years since I bought it, I'll continue to run the Mobil in all 3, including my new to me 94 E320.

Your dealer is doing a disservice to you and other owners of MBs with older cars.

yMobil 1 0W40 or 5W40 is used in the newer cars. I don't think You should not be putting it in your car.

Here in Vancouver the dealer still carries and uses 15W40 for our older engines (103 and 104 and maybe others). In hotter climates, or in summers, they sometimes put in 20W50. For very cold climates you can use a lighter oil for the winter though.

Not really, there are grades of oil available now that weren't around
back in the 90's. So you have more choices now depending on your climate.

Mercedes uses 0W40 or 5W40 Mobil 1 at the dealer depending on gas or diesel.

If you go on Mobil's website and use their "help me pick my oil"
feature, when I put in my 1993 400E it recommends 0W40 Mobil 1
which was not around in 1993 or in my manual.

Like you say though, just use a good oil, Rotella is a good oil.

Interesting. My wife put 80,000 miles on a '98 C280 that had over 70k when we got it. She was told, and we used, Mobil 0-20 all the way. I thought it was pretty thin, particularly since we live in Honolulu, Hawaii where temps range from 70 - 90 year round. Can't argue with the results, though.

Think I will move to 0-40 next time.

Clark, what is your opinion on oil choice for those of us who have the pre-chilled cams + rocker arms which are notorious for going flat? My understanding is the use of oil with a heavy zinc package will help slow the wear...Hence why I am weary of anything other than 15-40 diesel. (Obviously only affects those of us 86-EARLYYYYY 89 model years who did not have the warranty done on it).
 
#33 · (Edited)
ps2cho, you want to check the spec's of the oil
for phosphorus and zinc levels which is the wear additives.

For example Mobil 1 15W50 its 1200/1300 ppm

Mobil 1 0W40 is 1000/1100 ppm

On the other hand, their base Mobil 1 10W30 is only 800/900 ppm

To show you how good diesel oil is, Mobil 1 5W40 turbo diesel is 1130/1250 ppm

I would guess most 5W40 diesel oils follow suit.

Just check your brand for the phosphorus & zinc levels to be sure.

Rotella 15W40

Found this on Bob Is The Oil Guy, someone e-mailed Shell oil to ask
about wear additives.

"Shell Rotella T Multigrade Oil SAE 15W-40 with Triple Protection Technology, our API CJ-4/SM specification product, typically contains about 1200 ppm zinc and 1100 ppm phosphorous as manufactured."

For the 0W40 doubters

Interesting question I found on the "ask Mobil 1" FAQ. Note the car model.




Question: Using 5W-40 Grade Motor Oil Instead of 0W-40 in a Mercedes-Benz

I've been using Mobil 1 0W-40 synthetic oil in my 1992 500E Mercedes for 4 years now
and have been told to consider 5W-40 grade for my car. I live in southern California,
my mechanic only carries 0W-40 weight, and I want to ask if the 5W-40 grade is better
then 0W-40 grade all around?
-- Steve Vainshtein, Los Angeles, CA

Answer:

Both a 5W-40 and 0W-40 will provide the same level of protection at high temperatures,
especially if you are using a product like Mobil 1. As far as the 0W versus the 5W,
this should not make a difference for you other than at start-up.
The 0W would provide you a faster start-up at low temperature but you are unlikely to see
the differences in your climate. Either grade is fine for you and unless you are having any issues,
we recommend you stay with Mobil 1 0W-40 as it is specifically designed for your type of vehicle
