Compression?
Ok my car has 127,000 miles and i want to do a compression test to make sure everythings good. My buddys got a tester. What should the compression be at, around 100psi, or more?

RE: Compression?
yes it should be around 110 or higher but what you want is every cyclinder to be within 5 psi of each other

Those are very good #'s for the mileage thats on it. Seems like someone has been taking very good care of it, good luck.
