How often do you seafoam?

is there a limit to how much you can add to your vehicle in a year?

I add it to my gas tank about every 6 months. Obviously running every tank would eventually be a waste of money, so if you are really anal about cleaning your fuel system, running it once a month would not hurt. I have not done the combustion chamber in about 2 years though. I think that might be my parting gift to my apartment complex when I move out.

I've never used seafoam. My last zj was retired at 250k miles with the engine still running strong. Spend your money on something useful.

At least once a year and usually when I take a driving trip that is more than a tank of gas away. It does not sit in my tank for more than a day.
I drive from Midland, Texas to Miami, Florida almost every summer (for the past 5 years).

Some people say do it every oil change, stuff like this usually falls into personal preference though. Doing it all the time would be a waste, I'd say just do it several months past the last time you did it.

Never. I used a few times on my old Nissan truck trying to get rid of a mysterious lifter tick which would come and go after highway driving. I ran it for a while and then I developed a bit of bearing noise so I never used it again.

Change your motor oil regularly, used a good national brand gas from a busy station when you can like Shell, Chevron, etc. fix things when they break and do regular maintanace. then you have no need to look for a magic mechanic in a can.
