Well I have a modded 2002 Mustang GT with full bolt-ons no FI(yet)
There is just over 100k miles on it and doesn't burn any oil. I change the oil yearly and put about 4000 miles on it a year, most of them are driven hard or just cruising on the highway. I also plan on taking it to the track {just need some stickier tires) I live in texas so its hot all year long and and if we are lucky 3 months of winter. This is my first run with PP, I had RP the last few changes. Im thinking about running RP again this change, but I would like suggestions from you guys.
