The lb/in^2 in supra meter?
 

Hey guys, i know this might sound stupid... but dont be so harsh =). So my mk3, the meter next to the turbo it shows that i have 40 left? what does that mean? does that mean i should refill the oil in the engine? or is it like that? -thanks !

No that's the oil pressure guage it will change as the rpm's change. That does not tell you what your oil level is but if the oil pressure is low at high rpm's this could mean oil level is low. Toyota made the 7m to run low oil pressure and can be 6 psi at idle. To check oil level pull dip stick.

thanks for reply
