How in the world do you make sure that the cylinder walls are scored in an even manner that the rings can conform to???
The only thing that I can think of is the obvious - change your oil. Dirty oil will score the cylinder walls and cause compression issues and eventually will have you burning oil!
I have always made it a point to change my oil at 3,000 miles. Even my diesels got changed at 3,000 miles. Plus, I use the best oils I can find. Usually I use Amsoil if I can find a dealer near where I live at the time. Maybe that is why I get 200,000+ miles out of my old Accord, Jetta TDI, Suburban, and my old Subaru...
