has anyone added any fuel additives to tank. The results? good or bad and brand that was used. Thanks, FRANK

I use seafoam. Add a can every 4 to 6 months and put one in during the winter for storage. I use it in all my vehicles. It does everything, cleans the system, takes out water, etc. Used it for years. Bad thing is it costs 6 to 8 bucks.

Techron is another good additive. Techron reduces the accumulation of deposits in fuel injectors and on intake valves, and minimizes build-up.
