iwork at jiffy lube so 20w50 is pretty thick. if you want thicker ill go with a high milage
20w50. its thicker than any other 20w50 especially synthetic.
dont go sr or ka. all motor trottle response is always good. plus its more reliable than turbo. ill just get a silver top 20v 4age and do a lil bolt ons if i had a 86.
