I have a prediction about future Mobil 1 formulations

[Winston]

i,

Thanks for posting your experiences with M1.

Just wondering though, what weight were you running in those cars?

I personally think M1 tried to solve their noise complaints by thickening up their latest SM 5W30. (11.3cST @ 100C)

 

[Volvohead]

I've run M1 in my Volvos and have NEVER had a noise problem. I've been running the stuff since the 1970's without any problems in everything from big marine engines to tractors. It is in a very select group of high end oils that I would use in my R. But I also run RL, Havoline and Schaeffers in our fleet, so wouldn't consider myself a M1 groupie by any means.

I'd be absolutely shocked if M1 ate up the cylinders on that Saab engine. But I've seen compromised intake tract sealing do it.

I've heard several of these M1 noise complaints, and there may be something to them. But I've also heard from too many mechanics (shop and racing team) and machinists who love what they see inside an engine run on M1. The measured results just belie the isolated chatter on these boards (no pun intended). I'm not talking about used oil analysis, but measurement of the internals after a race, or in the course of doing another repair where the engine is opened up.

M1 may not be the best oil out there. It may not even be the best value for a particular engine's requirements. But generally, it still offers a very high level of extreme condition protection at affordable prices compared to what may be better.

Couldn't agree more and I've also heard the same. I'm sure in some engines, M1 makes more noise. I don't think it translates to wear at all. Many complaints about it could also be from M1 hates, which tend to be closet Amsoil dealers.

i, for every one of your complaints about it, their are hundreds that have had success with it. Corvette owners never run into problems using M1 and I know several guys that run them hard.

A lot of Corvette owners don't put enough mileage on their cars per year to know if they've made the right choice in oils or not though.

I don't think M1 is going to ruin any engines, however I do believe that you'll get a shorter engine life in an LS1 if you use Mobil 1 5w30 or 10w30. But it could be the difference between getting 200k out of the engine or 300k. And most Corvette owners don't even put 100k on them, let alone 200. I'm the guy who wants to hit 300k with mine.

I do believe Mobil 1 is a good oil, but I wouldn't exactly call it the best oil in the world. It works extremely well in Toyotas though.

I agree with you 100%

I think Volvohead is on to something, this may well be the the main emitter. However, there doesn't seem to be any associated topic wear

I was thinking of replacing my wife's Civic with a Corolla in 4 or 5 years, and if we do, it'll get Mobil 1 in it.

Chatterbox sufferers: Try the Pennzoil Platinum - it really quietted my 5.3L GMC engine.

 

[GoldenRod]

^^^^ Ok then fine, tell us which viscosity of the Platinum you used! If you going to brag about an oil, make sure you mention the viscosity.

On the topic of this thread, I think XOM will eventually move to Group III or Group II+ GTL basestocks for M1. To increase profitability, of course, especially if the motor oil end of the business continues to lag behind the profit growth of the refining and upstream businesses within the XOM behemoth.

Average joe Mobil 1 buyer doesn't care about basestocks, and Mobil lost that whole marketing arbitration with Castrol.

The whole thread looks like dedicated to ExxonMobile haters. M1 one of the best synthetic oil still. If you have a lot of noise then you have junk car, buy a new one or run heaviest dino you can find to quiet your trashbox down.

 

[Turk]

GR - I used the 5w30, it quietted up the cold high "empty rev" of the engine when the transmission held 2nd gear longer than it should.

 

[Steelhead]

the Mobil 1 shelves at my supplier is always cleaned out early and looks like it's been hit by a herd of women on a shopping binge
the overpriced Castrol GrpIII shelves are always full and orderly with dust on the cases

i quit the Castrol overpriced marketing pseudo synthetic years ago and went with the Real Thing, Mobil 1 including their ATF

even have a retailer that sells cases of Mobil 1 cheaper than pseudo SynTec, normal standard everyday pricing on both
