whats the word on rotella t, royal purple, elf, amsoil, mobil 1 (heard its not as good as it use to be?), red line full synthetic oil?

Very over-rated, may be fine for stock and 'stock like' modded cars but it doesnt hold up at 4x stock ouput, shears and wont hold viscosity. I have also run Pyre Power products and they are very good + the owner will do special additives if you have a need. He added Zinc to mine for added wear prevention. I also ran some Joe Gibbs oil and it was very nice, just very expensive. They make a really good dino breeakin oil.

The specs on Redline beat them all. I have heard good things about Royal Purple but they don't test their oil to the European specs which is a tougher standard than SAE so can't say technically how it compares with Redline or others. The best Mobil 1 for our cars is the 0W-40 according to their spec sheets but it still doesn't compare with the protection of most of the others. I was always a Amsoil sceptic but it rates almost as high as Redline in oil tests. Pay a little more and get the best. MGH

ski ya later

2nd.. absolutely the best and have oil report to back it up.
