Gumout/STP

[scheblo25]

Does anyone use gumout or gumout-type products? How often? Notice any changes?

I run Techron through Penny every ~5,000 miles.

I run nothing but Chevron or Shell gas. Never been a fan of the fuel additives. Just avoid the no name gas stations.

I agree. I usually put something in my car every few months for *shoot* and giggles, but there are already a lot of additives in the gas you get from the pump, so it's not really worth the money. I've never seen a noticeable difference.

I second the Techron, and also avoiding the no-name gas stations. I run Techron through every oil change or so. I don't know how much good it actually does, as was already said about gas already having plenty of additives in it, but it makes me feel a little bit better.
