My compression test results at 65,140 miles
Was getting my 60K servicing (at 65,140 miles) and my mechanic did a compression test on a Mazda tester for me since he was already working on the car.
My results:
Rotor 1 at 275RPM
7.8
7.7
7.6
Rotor 2 at 274RPM
7.5
7.3
7.8
Stats on my car: 2005 GT, original engine, 6M, bought at 12K odometer (already was 3rd owner - go figure), up to around 33K miles: 5W-20 dino was used and then 10W-30 was used. I also used FP60 then FP Plus in the engine for quite awhile, then used it with Marvel and now just using Marvel. May go back to FP products again. I have used a couple bottles of Lucas UCL in the past year. Never used pre-mix. I also try to take it to 8500-9000RPM at least once a day.
