...restrictions on them since 80s? Is it because chevy still likes to use builds from 90s with just improved fuel injection and heads? Or there engines wont tolerate tighter bearing clearances and still get the same mpg?
I know you guys have already answered this question a million times....I've been doing a little research online and it's kinda tip for tap....Reason for me asking is I'm about to put the 2nd engine in this car and want to start off right this time....Also synthetic or non?...Thanks Again for you...
