Metro Tech Comments: " VF6807 - dust/dirt. Cylinders; pistons; rings wear. **Suspect lead based additive**
I did use a can or two of fuel system cleaner because I have a continual problem of additive buildup on the intake valves making the car almost impossible to start. This car sees only severe service use, I am retired and my daily trips are to the coffee shop, grocery shopping etc.
Any comments if I can get away with one oil change per year? Thanks.
