What would be the best additive to clean out injectors and valves and all that good stuff.
I have heard seafoam does wonders but there is also that STP stuff.
What you guys recommend?

Techron or Gumout with Regane.

Are these just added to a tank of gas?

Yep. Your thread title is "fuel additives" so that's what I posted.

Ha, yeah I guess that is true..My mistake.

Another would be considering Seafoam.

Steer well clear - stuff is crap.

Try using Search, bud. This is what it's for - to help you avoid doing sumptin' dumb ...

I tried searching but did not find a whole lot of help, I'm glad you have managed to do it for me.

Yea I barely managed


Search > Advanced Search > Keyword = Seafoam; select Title Search > GO

82 hits.


There's also something called Gooooogle: http://lmgtfy.com/?q=seafoam+bad

127,000 hits.

Next.

Do you get off on being the great search man?
I asked a question, that's what you do on a forum, I'm sorry that i did not search for sea foam when I wanted answers on additives other than sea foam.
Thank you GLC I'm going to try Techron.
MGD you're an ***.

Right. Better an *** than a lazy SOB, which is what you appear to be.

BTW - those posts also detail additives and other treatment recommendations - guess yer too lazy to read them, though.

Would you prefer another lesson in Search - this time with 'fuel additive' as the keywords?

Some people's lazy, ignant kids ...

I'm not a lazy, Ignorant kid, if that is what you were going for there, I just happened to ask a question and get an answer rather than read through post after post after post. Simplicity is not laziness.

MGD seafoam is very very useful.......

you can use it to strengthen up your moonshine, and it's way safer then anti-freeze

Russo is too young to be talking about moonshine with!

I like Lucas Oil

A local radio show host on car repair is not much on using additives. But did testing on Techron and said it did make a difference in the engine keeping it clean. But he is big on using a quality gas from the start.
