0w-30 Signature Series. FINALLY put it in the '01 Saturn. I expect this oil to remove all the sludge built-up from the previous 3 runs with Pennzoil, improve my MPG by 20%, keep my four balls from wearing out as fast AND go 70,000 miles until the next oil change! (Some say you can go twice as long synthetic oils compared to conventional, since Amsoil recommends 35K as standard service, I figure 70K shouldn't be a problem!)
Seriously though, is anyone seeing any MPG improvement with Amsoil 0w-20 or 0w-30 oils?
