hi, im new to the site, but love trying new oils out. i have been mainly a amsoil guy.....i have a 2008 srt-4 caliber which comes fro the factory with 0-40 m1, and switched it to amsoil sig. series 0-30.
my question is amsoil tech recommended the ss 0-30, but the more i research, it seems i need to stay with 40 weight with this turbo engine.
im pushing almost 400hp, and want to make sure the amsoil ss 0-30 to protecting my engine and turbo...what do you guys think???5-40, rl 0-40, maybe german castrol 0-30, thanks
