Ok I am new to the Mustang world. I bought a 69 Fastback with a 351W 2 weeks ago. I just had a compression test and the #2 and #8 cylinders where at 90 dry. The rest of the cylinders were at 120-125. I am a mile above sea level here. When I change the oil should I have it flushed and add engine restore? Will synthic oil be bad for it and cause it to burn more oil? Any recomendations to help the problem until I have it rebuilt?
