Any thoughts about fuel additives? I've got 6k miles on my '02 D/A now. A buddy is telling me I should be running some through with every tank to keep the injectors clean. This is after he had to replace a piston in his 6.5L (w/ 22k miles on it) after an injector clogged.
Thoughts? Opinions? Has this been discussed before? (likely)
