ever use that royal purple oil treatment? its supposed to help with low compression and high mileage engines. I'm thinking about giving it a shot when I replace the oil.
Hantke,

Marvel Mystery Oil is a common additive for low compression issues. Many members report good results from it. If memory serves it is around $24.00 per gallon at major Wal-Mart supercenters.
