I would definitely suggest the school thing.

It would be really great if I could get one piece of knowledge across about mixture adjustments. That one thing is this: any car that has an oxygen sensor (1980 and above) AND is functioning properly can not be made to run better or worse by adjustments.

IF YOU ARE adjusting a car (in this catagory) and are changing the way it runs then the car is BROKE!

AND the only thing any of this has to do with oil pressure is engine speed.
