Will be taking truck in for the dreaded plug change in a month or so. Question will help to run a couple of cans of seafoam through the tank before taking it in or not?

Looked through post and for every 3 saying yes there are 3 saying no. Since alot more have been changed maybe get better input.

 

I'm getting ready to do mine and I'm going to run 2 containers of chevron techron fuel system cleaner through mine before with about 20 gallons of gas. Based off my thread and 88racings experience that seems to be a pretty proven idea on what to do. If it isn't what's been helping people I'm sure it hasn't been hurting them!

 

No.

'88 will elaborate -

anykind of cleaner will help.mine were a nightmare to get out and i let them soak in the ford carb cleaner stuff over night(which did nothing).

 

I've always ran 93 octane (custom tunes) so that and run cleaner every now and then so I guess the seafoam can't hurt right?

Run two tanks of gas before the plug change using a bottle of Chevron Techron each tank....

Seafoam is the equivalent to soaking the plugs using penetrating oil....

 

If you concentrate on Quinton's posts then you should be good to go.....

 

thanks just trying anything to help

 

I used (2 tanks of) Techron & (1 tank) Sea Foam and out they came perfect. Try or use both, can't hurt but I'm no fuel chemical expert.

I read in a few posts on here that dealers insist before a plug job with them you run two carbon cleaners through two tanks of fuel.

 

1/2 of a can of seafoam to a 1/4 tank of gas, flog the truck for 4 or 5 miles, stop engine, pull plugs hot.

I am 16/0 with this method, never broke a plug and the customers truck was over 100k, my personal truck was at 70k. Plugs came out screaming all the way but both sets start to finish in under 2 hours.

I swear by the stuff, been using it since I became a mechanic. Can you over do it? Sure.
Do you need to run it all the time? Nope.

I run it right before a plug change just to help break up carbon and call it good.

 

It isn't the popular vote by any means, but I have had good luck with Seafoam and will continue to use it. You can do the same thing that a shop will charge $130 to do for $15 in your driveway.

 

Any parts stores carry this stuff or do I have to order online??

 

Most any auto parts store will carry it (oreilly's, autozone, etc). I believe many Wal-Marts carry it, too. Make sure to get the fuel system cleaner from Chevron, not just the Fuel Injector cleaner. I believe you get more of the "techron" concentrate for your money. For what it's worth, I'm also dumping in a bottle of SeaFoam into a 1/4 tank of gas before I run the techron stuff prior to the plug change.

 

Thanks. I think I'm going to try to change the plugs this weekend and I was going to run this through beforehand. You wouldn't by chance know if you can rent the lisle tool from anywhere?
