ehhh... AMSOIL oil + AMSOIL bypass... can't beat THAT...

If you are interested in buying I reccomend you contact this guy http://www.gadgetonline.com/AMSOIL.htm

he really knows his stuff, and he is a toyota guy. i think my bro can resell the stuff too, but he is on deployment in korea. Gadget is a top notch guy who will answer any of your questions, my advice is to read his site, read the amsoil site, and then check out my bros site (:

PS NAPA does NOT carry amsoil, they have contracts w/ other oil mfctrs. Alot of specialty 4x4 and hot rod shops carry amsoil though... Check the BYPASS out, that is what makes the most difference...!!!! people seem to forget that...
