Hi All,

just bought a used Honda Accord LX 2004 and i would like to know what Fuel System Treatments & Cleaners do you advise me to use.

Thanks

PS : A store near my house sells brands like STP and Seafoam

 

Kind of a debate on this.

I have used Seafoam in my cars before.

 

The loyal opposition here; no Fuel SYstem Treatment or Cleaner needed, ever (or at least until your engine is in rough shape and suffering from lots of blow-by). Says so right in your Owner's Manual.

 

I use Lucas. I know the manual says don't use them. But with all the ethanol and others junk in most gas it gums everything up. I had to replace a fuel filter @ 150k miles. That's not normal in my book. I took a air compresser to blow it out cause it was clogged. And it come out like black tar. After put the new one on .... car ran like a champ. I only use certain gas stations now. I definitely notice a difference

 

Unless your car sits for long periods of time, Ethanol will not gum anything up, in fact, it can act as a solvent and water absorber to keep the fuel system even cleaner than straight gasoline.

 

The gas I've always used has 10% ethanol. I happened upon a local station that had no ethanol, so I tried a couple tanks. The engine ran smoother with the ethanol gas, so I switched back. IMO, as long as you use "Top Tier" gas, you shouldn't need anything else. I used to use the Chevron Techron stuff, but I don't think it was doing anything for me.
