I came across the following on the Crower FAQ page http://www.crower.com/misc/faq.shtml :

"Crower does not recommend the use of synthetic motor oils in any racing applications, particularly hydraulic and flat tappet camshafts. The minimum gains in horsepower are offset by the excessive wear to cam and lifter surfaces. Crower recommends Kendall GT-1 (20W50) Petroleum based motor oil in all high performance applications. If your manual suggests running synthetic oil, then do so. We have found, however, that the benefits do not outweigh the costs."

I don't understand why a synthetic would cause excessive wear to the cam & lifters (even in racing applications). Would someone please explain this to me?

Thanks.

Thats alot of bunk. Syns dont cause wear and if fact reduce friction thus reducing wear as compared to petro oils. I would not buy a cam from them if I could not use syn.
Maybe they have some tech from 30 years ago that remembered a glycol base syn that was not a good product, but those are long gone. The top racers in the country, NASCAR, Drags, road racers, have all used syns like Amsoil and Mobile 1.
Logic dictates, reduced heat, cooler running equals less friction, less wear. Plain and simple. The writer of that article doesnt know what he is talking about.
Of course this is just my opinion but Ive used Amsoil for over 25 years. Never had an engine wear out, and now my Camaro is sipping Amsoil too. Best transfusion its ever had.

The Aug. '02 issue of HOT ROD has a good right up of the pros/cons of synthetic vs. conventional lubes. But, as it was pointed out already, the manufacturer recommendations are always important to follow.

I agree and the manufacturers of the oil warrant their products. Amsoil has warranty on their oil for 25 years now. The cam maker has a warranty on their cam Im sure. So the consumer is protected if they dont abuse it.
There continue to be articles in magazine after magazine, with new 'tests' of syns versus petro. Funny thing is, they have been tested by car owners for decades and found that syns are better. Thats why you now see Quaker and Pennzoil and Valvoline coming out with syns too. They are just behind the pack in research and technology is all.
