pretty much any fluid in your car that is transferred by a pump.

do u have a tach for that? or is it just something u pull out or what?
if there is a tach then ima look at my dad's toyota sequoia and tell u his pressure

well from what i understand, and now i will correct myself, its not just fluids, cause i remember now , PSI is also gonna measure someones turbo boost.


Yes my car has an oil pressure gauge, but i think the turbo models have a boost gauge in place of the oil pressure gauge.

Hopefully somebody else with more knowledge and understanding of the whole PSI thing will come along and educate both of us a little more.

my dad also added that it adds tire pressure mesurements too. is that true?

yeah its also measures tire pressure

i also noticed on my dads main gauge it says "x1000RPM" whats that mean? (if its as worse as asking what hp is then ignore that comment)

well on your dads rev meter where it says x1000rpm means revs per minute

it goes from 1 - 8 so 1 x1000 = 1000rpm and 2 x 1000 = 2000rpm etc thru the range :)

cool thanks. is revving good for your car?

basically no free revving... i.e. in neutral and just rev to like 3000+ rpm is not good

if in your car or supra etc... find out where the power starts falling off and change gear there.. usually 5000rpm in a supra... but don't make this daily practise :)
