So out of Mobil 1, Redline and Royal Purple, the winner is?

 

Based on oil analysis reports I've personally seen, Redline is the clear winner out of those three. Amsoil will also give you excellent results too, as well as German made Castrol Syntec 0w30.

 

Can anyone prove the validity of the statement made a while back about the BMW recall? Why would an entire year of engines be recalled for Mobil 1? That seems a little fishy to me...

 

Sure... go visit any of the BMW websites and start throwing out that you like Mobil1 in your 2001 M3. You'll get flamed faster than Bin Laden and Jesse Jackson at the local KKK rally.

As for validity, every 2001 BMW M3 owner was sent a notice in the mail asking them to visit their local dealer for a complimentary oil change. The oil was changed and a sticker was placed on the radiator fan support saying that the oil specification for warranty compliance was Castrol Synthetic 5W60 oil... period!!

Many many other also lost their engines. Many lost and were forced to pay out of pocket replacement before it became a national outcry. BMW denied it for months saying it was excessive RPM on the SMG models but was later forced to cover the claim due to the computer logging not able to pinpoint the actual time of the rev beyond 8500 rpm. The other part of that was the computer was supposed to force an upshift and in many cases it failed to do so, which also negated the dealer and factory claims that the failure was limited to those who were abusing or racing their cars.

So, eventually the blame fell on Mobil1. You may recal that in later 2001 and early 2002, Mobil1 changed their "Formula" in order to appease the market and to show they were making changes to their product due to the related failures. This was in forsight of a huge lawsuit from BMW which was also soon to be from GM on the Z06 Vettes. Many early Z06 owners were losing engine on the road race tracks across the country and having pure hell with the tranmissions failing.

Dodge also had the same claim that Mobil1 was to fault for the #3 bearing failures on Vipers that were being road raced. The cure was to simply change the oil type and the car would perform fine on the track.

Just a little history from the inside of the curtain...

 

this weekend i just switched from Royal Purple 10w30 to Amsoil 10w30......its slightly noticable that the car runs/idles smoother and quieter.

i dont do oil analysis, so i have no idea which works better, but just pointing out that i noticed a difference.

 

You sure would notice that... Take a guess why? If your engine's new oil has a great compressibility meaning it can hold its hydraulic property as good as RP, then it will give you less valve lift and thus a nice smooth running engine. Kinda like taking a nice lopey cam and sticking a nice family sedan cruiser cam in your fine LT1.

We have hydraulic lifters... if the oil you use changes the characteristics of your idle quality and softens it, imagine how poorly it will give you performance when you need it at high rpm...??? I would hope your sake you can get a refund on your purchase. I would rather the lumpy idle and the greater power than fresh oil and smooth camming engine.

Just an observation...

 

You're starting to sound a little too much like a sales rep. This post is starting to **** me off. Its going against EVERYTHING I have ever been told about oil....:blah:

 

im just experimenting with different oils..........i have no bias towards any company. neither one gives me money, and they are both damn expensive, so i really dont care. (although i dislike mobil1 and wont use it)

but thats a pretty bold statement against amsoil...........so you say that im losing power?

what is the technical basis that proves the amsoil is going to run worse than the royal purple?

i thought amsoil was very highly regarded.

the ole butt dyno is not that accurate, but the car really doesnt seem to miss any power, actually the opposite, it seems to pull harder/smoother now.

btw, my oil pressure hasnt changed from one oil to the next, it is always perfect, and my car never loses a drop.

 

Just an FYI, but the problems with the M3 engine weren't with Mobil 1, but specifically with the 5w30 viscosity in those engines. In fact the BMW dealers weren't putting in Mobil 1, but they use a "BMW synthetic" 5w30 which is actually Castrol Softec. The problem is this viscosity is too thin for this engine. They now spec 10w60, which is a Castrol oil called TWS.

 

Well I can argue that point cause I actually owned one of those M3s. BMW was looking for the problem and found it to be the oil. Since changing, they had no failures related. All the other engines use the lighter weight with no problems... it was just those with specific Mobil1

I am done on this subject. I think we have beat it to death. If you like peanut butter and it gives you great results, then by far use it with joy.

I have just been stating my experience and the tests I have conducted first hand.

 

If you truly owned one of those cars, then you should've known it wasn't the Mobil 1 causing the problems, but a batch of faulty bearings, combined with them specifying 5w30.

The fact that you actually believed what that Royal Purple tech told you about why their viscosity thins out, shows how little you know about oil. I posted that quote on the oil board and they got a good laugh out of it.
