Castrol EDGE Sport 25W-50 is the ultimate product dedicated to satisfying modified engines, push-rod technology, street machines and the big bore competition engines.
i use castrol edge sport 5w30 in my turbocharged colt ralliart.
and on good advice i switched from 25w50 to the 10w60 in my supercharged mini.
i've tried KMX but i wont be buying it again, i can usually get valvoline or some other brand name oil for less money. Sorry but i'm not a fan of home brand stuff. But i did give it a go.
also i find it puzzling when people say penrite oil doesnt give as much oil pressure at higher temperatures, considering it nearly always has a higher viscosity rating than the equivalent oils from other brands. 20w60 instead of 20w50 etc.
