Is Mobil 0w-40 really that great?

BMW for instance is one! As Porsche is now wholly Ownerd by the VW Group (Holding Co) we may see some interesting developments there in the future

As well - I know in Germany at least - the FF lubricants are typically supplied by more than one Oil Company - Daimler is but one for example. Exceptions like Porsche do exist

The first synthetic FF was by Porsche around 1992 in the 928 GT - it was Shell's XMO 5w-40


Hi Doug, I thought MB exclusively uses M1 for FF. Who are the other suppliers?

MB uses Mobil 1 0W40 exclusively for AMG vehicles only. Other gas vehicles in the MB lineup may come filled with Shell Helix Ultra 5W30 (or something to that effect). I am not sure how many other options they might have for their diesel vehicles.

Hi,
vinu_neuro - As "Ïl" has noted the AMG range gets Mobil 1 0w-40 exclusively - some other models may too. As for the rest, I cannot give you the current suppliers but I can assure you there is a number. This is no doubt for capacity and security of supply and other logistical reasons

^Thanks for the more detailed response Doug!

So unless we believe in the conspiracy theories that a manufacturer only wants our engine to last xxx,xxx miles, the best oil choice would be exactly what the manufacturer has designed / recommends, whether it is an OEM fluid like TGMO or MC Syn Blend or an "aftermarket" oil like Mobil 1 0w40.

I have a 2010 Challenger SRT with 6.1L engine. The vehicle came with Mobil 1 0W40 and that is what has been used to date. The vehicle currently only has 4300 miles on it. As many are aware, Pennzoil is now marketing a 0W40 “SRT” formula created by Pennzoil and SRT engineers to meet the special and demanding needs of SRT engines (whatever those may be). I am sure that Pennzoil 0W40 is a fine oil meeting the specs called out for the 6.1L and 6.4L SRT engines in their respective owner’s manuals. However, based on the used oil analysis on this site for Mobil 1 0W40 under some extreme conditions I see no reason to switch. Opinions?

Get a used oil analysis of both and make a decision

I don't think you will gain anything by switching. Stick with the Mobil 1.

I don't think they testing engines out that far.

I think if Chrysler is working hand in hand with pennzoil to develop an oil made for their engines I would venture a guess and assume that it's perfect for their engines.
I know Mobil 1 0w-40 was created by zeus' own hand however if dodge is going to go to the trouble and make an oil just for their engines I would use it IF it was in the same price range as the Mobil 1. If the pennzoil was cheaper I would use it first,if they were about the same price I'd still go with pennzoil and if the mobil was a few bucks cheaper then mobil it is.
Either way I don't think a guy can go wrong using one or the other.

What else is quoted in the owners manual for the 6.1 for the oil spec other than the viscosity? CHrysler has 6395, but any other for the SRT besides 0w-40 or 5w-40 synthetic?

The original manual from my car purchased August 05 says Mobil 1 0w-40.

They also allow 15w-50 via TSB if your oil squirters warble at idle when hot.

All the brand recommendations are is marketing, pure and simple.

The 2010 6.1L calls for 0W40 API Certified SM GF-4 meeting MB 229.3 / MB 229.5. Chrysler Material Standard MS-10725

That's a term I've never heard before. How does one determine if one's oil squirters are warbling at hot idle? Seems like it would be [censored] inconvenient (and messy) to take a look inside the crankcase when the engine is running.

It is an audible condition.

I've still seen SM/GF-4 Castrol Edge with Titanium on the shelves up here. As for Mobil products, I haven't seen Mobil 1 0w-40 SN up here either, but vanilla Mobil 1 was one of the last products to switch from SM/GF-4 to SN/GF-5. The Edge with Titanium is that way simply because it's at prices that make Royal Purple blush.

I wouldn't see a reason to switch, either. Get whatever is readily available, and if it were me up here, that would have to be the Mobil 1 0w-40. Given the miles you put on the vehicle, you'd be hard pressed to tell the difference over the life of the vehicle.
