However, there was a dyno-test done by Fast Fours & Rotaries not too long ago that did a comparison of a bunch of top-of-the-line synthetics including AMSOIL and Royal Purple. Their conclusion is listed below and you can see the entire article at this URL: http://www.guarding-our-earth.com/amsoil/fastfour.htm ---------------------------------------------- Conclusion "Although we've provided criteria to pick and choose an oil, the stand- out to us appears to be AMSOIL, rating well in the viscosity and producing good horsepower. "With the variety of grades, use this test as a guide but always follow the manufacturers recommendation. But if we were to stick our neck out in the anticipation of the law suits, from the information we gathered specific to the supplied oils in this test, we'd rate the oils in the following order: AMSOIL BP Visco 5000 Mobil 1 Mobil 1 Hi-Tec HTO Shell Helix Ultra Royal Purple Castrol R Castrol SLX Torco" Mike Kaufman Sent via Deja.com http://www.deja.com/ Share what you know.
