Motor Oils

[Marty Kocse]

All this bad press about Mobil 1 really makes me want to put an oil additive, like Prolong, in the mix.  All I've heard is that Porsche does NOT recommend any oil additives.

Has anyone out there used an additive like Prolong with any success in a Porsche engine?  I'd really like to know the +/- of using that type of product along with Mobil 1 0W40.  All I want to do is protect my engine the best way I can without compromising the reliability of the motor.  Any suggestions?

Guys, do yourselves a favor and read the excellent recent threads on Pelican and Rennlist. A lot of good info there.

That linked-to article from an Australian hot rod mag has been widely discredited. The magazine itself published a retraction. Not sure why it's even still posted--the owner of that web site must be a real RP fan. The test they used was ridiculous. Like the old Slick 50 commercials on late night TV. Has NO bearing (heh) on how the oil will protect your car.

How about just sticking with a reputable brand of oil and changing it regularly?  I have seen a lot of engines die in my day, but have never seen one go from "bad oil".

Has anyone?

You guys CHANGE your oil? 

I thought we put 12 quarts in so it would last 3 times longer than my Toyota MR2 that takes 4 qts

There is no disputing the fact that the European car manufacturers make some of the most powerful engines on the planet. Current engine architecture relays on a very compact package to attain this feat. In doing so many of the bearing dimensions have decreased in overall surface area. This transmits into more forces acting on a given area during one crankshaft revolution. We must also not forget that these engines are also seeing much higher RPM operation than engines in the past to attain these power numbers. This is requiring OE lubrications systems to do what was not expected of them in the past. No matter how often you change the oil in the engine if the properties of that oil are not appropriate for the physical forces acting on the rotating assembly than a failure is eminent. Another area that has seen a tremendous amount of advancement particularly in the import segment is valve train technology. A great deal of the power level increases in recent years can be directly linked to this area of the engine. These new systems have put new demands on the oil manufactures to produces products that will be capable of not only keeping the bottom end together but also the valve-train, camshafts and a multitude of technologies that allow the manufacturer to manipulate cam timing, lift and duration. ACEA specs address these specific issues where API specs do not.  My recommendation is to run oil that has ACEA specs that are appropriate for the specific engine your servicing. This may require a little research but I am confident it will be less time than an engine overhaul requires. http://WWW.ELFOils.us

my 996 calls for 0W40.  I don't see that listed on the elfoil website.

 

Steve, can you put this in english?

Mobil one news on Rennlist.  It appears they have gone back to the old formulation before the extended wear version.  Follow this thread.
