My race engines get GAS style oil... my diesel gets
DIESEL style oil... diesels dont turn 9000 rpm(I have
turned my race engine to 9600)... the thing with my
race engine is it starts at 5600 and goes up(never seeing
below that point) a diesel is a low rpm engine... they
both have a SAE standard but those standards are different...
if I were running a flat tappet at high rpm(7500 and
up) I would be running gas SAE oil with a zinc additive...
but on a FT I would be running a zinc additive no
matter how high OR low I turned it... that just me...
everyone has their choice
