I did a compression check, because I couldn't pass smog and a rough idle, and one of the cylinders at first was only 60psi, then. 100, then 150. So I put 20-50 oil in the cylinders and it went up to about 125psi. Would this mess up the test because I didn't use 30w. The others were fine 101,125,150. I am trying to determine wether to sell her or fix her.
Thanks
