My interval has been 3,000 miles thus far. I realize that is quite often. But it is a saturn so I don't extend drains on it. However I'll probably go to 5,000 this time. I did one run of max life semi syn and one run of max life synthetic.
Imo the claims of penny oil cleaning so well is kinda funny looks like valvoline does a great job to. Very pleased with the results. Btw the car before I got it ran 5000 intervals with penna oil and then pennz high mileage.
