Hi guys,
Yes , sorry ,but another oil related question - I'm sure has been asked before but I cant find a definitive answer.

I know its expensive but have decided to put Mobil 1 0W-40 in my 2003 ML270 at the next oil change.

I have 2 options as far as I can tell:
Mobil 1 0W-40 turbo diesel
Mobil 1 0W-40 new life (marginally cheaper)

The mobil website recommends the new life for my vehicle (even though its a diesel).
Having read far more than I ever wanted to on oil, i'm still a little undecided. as far as i can tell, diesel specific variants have more detergents in, however am I correct in assuming that the newer modern day oils are now good for both petrol and diesel (and the diesel specific ones are now more for low ash/soot for correct DPF performance?) my car doesn't have a DPF.

My general thoughts were that I should go with the turbo diesel version until the mobil site added to the confusion and recommended the new life.

Anyone got an opinion on this please.
Thanks.

Only that I'd not use Mobile and go for Shell, one of only a few oils mine has not used any on..;)

Why?
 
I think it's more to do with swapping to Mobil 1 if the car has been run on it from new then no issues but when people have swapped to mobil 1 I've seen complaints of high oil consumption and engine oil leaks developing and this was quite a few incidents not just an isolated incident

Never used anything on my cars except Shell Helix and never had a problem

Just my two penneth but I always think it's cheaper to learn from other people's mistakes
 
I have used Mobil 1 in my W210 since I've had it (circa 5 years) and it has been spot on. No idea what was used for the first 150k miles but at Costco prices it was a no brainer.

I have bought the MB stuff for my next couple as it was even cheaper on ebay for once

I'm suprised. What cars were these?

I've used Mobil One all my career mostly and I've never come across this.

IIRC some of the worst were performance Vauxalls VAG cars and the c class 3 door. It's a while though now been out of the trade nearly 3 years so my memory may not be that good either that or it's my age lol

You can use either, take a look at my posts on these threads for more information:

These oils are not completely the same because of specifications. We did not get some specs for petrol cars for Mobil 1 Turbo Diesel 0W-40. But if we are talking about Mercedes-Benz specs - it's ok to use Mobil 1 Turbo Diesel 0W-40 in petrol engines also.
 
Mobil1 was one the first widely available full-synthetic engine oils (not the first on the market though - that was AMSOIL - but it were not easily available outside tbe US).

I used Mobil1 5W-40 on my 1982 Astra (1.8L OHC) back in the late eighties with no issues.

However the talk at the time was that some types of rubber seals originally designed for use with mineral oils can react with full-synthetic oils and cause leaks.

Not sure how long such rubber was in use for, but I think that by the mid-nineties most engines were specified with either semi-synthetic or full-synthetic oils anyway.

I used Mobil1 on my 2001 V6 Omega, but for some strange reason it seemed happier with the GM-Branded Semi-Synthetic oil which was rumored to be made by Fuchs at the time.... the GM-Branded oil causes less 'mayo' under the filler cap on short journeys, and the engine had lower oil consumption, which is the opposite of what I would have expected.

These days I just go by the MB Spec Sheet and happy with any brand that meets it.

My 2006 car with the M271 Kompressor engine so far had Castrol and Shell Helix Ultra from MB dealers, as well as Mobil Super 3000 XE and MB-Branded 229.5 (presumably Petronas?) from specialists. No issues, and negligible oil consumption.

Cheers everyone,
i'm going to go with the Mobil 1 New life as its the right spec and from what I can see is OK for use on diesels and is pretty identical to the Turbo Diesel version but I can get it a lot cheaper at the moment. (Still not sure if the Diesel version has got extra detergents or whether it is a pure marketing thing, I read an interesting point elsewhere where someone said it was the same oil but labelled differently due to the fact that historically diesel owners didn't want to use oil intended for petrol engines and vice versa, although the newer oils meet the spec for both, having 2 labelled differently for the same oil keeps everybody happy),

Thanks for all of your input

I've only ever used mobil 1 0w40 in my 270cdi ML since new, it has now covered over 260k miles and still runs and sounds as new.

It is actually the the original recommended oil for my car by MB.

As my subsequent post its seems never to be a problem on cars that have been run on Mobil 1 from new
 
I've used mobil1 0w-40 on my c220 cdi 2001 and the engine was quiter,and topped up liter only between oil changes,usually 20000mi.But this year will go for Castrol or Petronas..

I completely understand that, unfortunately some brands only just meet the spec. whereas others exceed it. Takes some digging to find out which ones are which through..

I agree, but:


1. Mine is a 4-pot M271 producing mere 143bhp :)

I don't think it needs specialist oil.


2. The original spec for my engine is 229.3 so when using 229.5 I am already over-specifying the oil spec...


So yes you are right but it probably does not make much difference to engines at the lower end of the pecking order ;)

Nothing wrong with that bhp, for me much more fun can be had in lower powered car's..:thumb:
