Hey everyone. So I have a beater 1999 Accord that I got for free (and sort of don't care about) but I also got these two products for free. Since it has 191k miles right now, I'd like to experiment. I have a container of Seafoam and Gumout Multi System Tune Up and I'm wondering how I should use them. Gumout Multi System Tune Up seems to have similar ingredients to engine flush formulas (cause it has Naptha or something like that in it), as well as PEA. Seafoam seems to be something else. To be honest, I'm not really familiar with these terms and chemistry and I'm just going off some light reading I've done here on these forums. I was thinking of doing the following at the end of this OCI:
1) Gumout Multi System Tune Up in the Oil - Put it all in the oil, run the car for 15 minutes (as on bottle) then drain the oil.
2) Seafoam in the gas tank
Or do you guys think I should switch it up and do Seafoam in the crank case oil (I hear people drive on this for 100 miles or so before changing the oil) and Gumout Multi System Tune Up in the gas tank? Also, if I were to go with the "engine flush" route, would I pour it in when the engine is dead cold, or mildly warm, or right after the oil was at operating temperature? Thanks for the advice!
