While we're talking about fuel in another thread, we're were talking about about fuel system cleaners, fuel line, injectors and other types of "Pour in the tank cleaners", What is the best ? What have you used that was the most effective of the lot ? I'm sure some of you folks have an opinion ? Let's hear them ?

Techron

Techron by Chevron. There are so many people on this forum who have used it successfully. It has helped many users with inaccurate and sticky fuel gage senders, myself included. If you're having a fuel gage problem a couple of bottles will usually fix the problem. An occasional bottle will prevent it from happening. In general it is just good to use, I use it in all my vehicles.

Well I've seen Chevron Techron, and BG44K and Lucas make a fuel system cleaner, I wonder how they work. But your quite right, Chevron Techron is the winner in the favorites class.

Techron for me.

Techron or SeaFoam.

Won't be using Seafoam anytime soon. Put it in my F250 deisel and apparently it swelled the o-rings some where in the fuel system, causing a good bit of leakage. All returned to normal after my next un-treated fill up.

Seafoam.

The issue with the fuel gauge is that sulfur builds up on the fuel sender. Techron is supposedly formulated to clean up sulfur so it's the favorite here.

I can't find it in England so I've used a Redex product which seemed to work too.

Techron and check this out....

Techron by CHEVRON is the best. There is no other substitute.

I use Techron every ten tanks or so. Also use SeaForm.....half in the tank, the other half in the brake booster vacuum hose, once a year.

Yep,Techron is good and BG44K seems to be the strongest cleaner.I use Amsoil Pi in all my cars at oil change time.

Does a good job for temp cleanup.

Yes I almost forgot about 'Seafoam' another odd but recommended cleaner I've been told is Xylene in the fuel tank. But to me Xylene is a little too strong for me. I'd be afraid of melting some rubber parts. I have some cans of BG44K in the basement and a bottle of Chevron Techron here so I'll go with them until I run out. I have a pretty severe clogged intake valves. The Chevrolet dealership did a great job using the GM type/named can of what I guess is "Seafoam" which cleaned up a lot of the deposits. It's a 75% better now. And I asked if it can be done again, but they said just get a few bottles of Chevron Techron from a Autozone or where-ever and use a bottle with each fuel-up of premium fuel. The problem is that instead of using premium fuel, for the last five years the owners used only the cheapest regular gasoline. It was a 39 month lease, so the owners figured "What the hell". But oddly enough, just like Corvettes there's no marking on the dashboard or on the fuel door that the car needs 91 octane or above. And I can only guess Nobody ever took the time to "Read" the owners manual. Corvette owners really devour the owners manual once they buy a Vette.

We also use BG44K in the shop for particularly bad cases.

Techron.

Right before the gas gauge starts sticking.

Seafoam

Ya know, oddly enough the guys and gals over in the Porscheforum.com folks had been talking about "Piston Slap" Yes, even Porsche's have piston slap, and at that price of a Porsche you'd think WTF ? But they have it also, so they recommended the BG44K and it does work for about 350 miles but the piston slap slowly comes back.

Techron/Seafoam, usually one or the other.
