Don't put seafoam in the motor it will wash the moly and zinc off the bearings and you will have no protection. The additives in the oil and the moly on the pistons forms a barrier on the metal parts once formed they dont need alot of maintenance. That is why I use a good synthetic oil. I have notice that there is a lot of people complaining of bad gas mileage (me included). I wish I knew how to fix that problem, Its probably lots of ethanol in the gas.

 

There's been mixed reviews on carbon removal and possible engine damage. Should this be a limited treatment say, every 50,000 miles or even at 100,000 miles? Seems like repeated use could eat into car parts. I'm at 55,000 and have considered doing this.

 

Ive used it in a few mini vans with no problems, used it through the vacuum line and being careful not to hydro lock the engine. I just would not use it in the oil for the above reasons. Seems that the problem with bad gas mileage is that ecm needs to be reset. Read somewhere that reseting the ecm should be done every season change.

 

I read and watch seafoam on Youtube...looks impressive. Too bad can't find any in Australia

 

TTT. A DIY for the Fit with picture would help.

 

Lol... there is one... just search for it... as for myself, i did it once, and i won't do it again, i'm too worried it damages something, and seen no actual improvements...

 

i seafomed my gf prelude when she firts got it she was getting like 15 mpg now shes getting 21!!! that was a huge improvement

 

For those that have small engines, motorcycles and generators, had success with seafoam cleaning out carbs without disassembly fed it in by disconnecting the gas line, dripping it in, opening bottom of bowl, draining water and then reconnecting gas.
