Using Seafoam

[redo75]

Does anyone use Seafoam as a additive to gas in smaller quantities such as 50 ~ 100 ml per full gas tank?
Looking to use it every few gas tank fulls to keep injectors clean. Anyone had good / bad results?
I used to use the red CTC injector cleaner in the old per use bottles but not too happy with new stuff.
No, I don't want to upset the locals with smoke bombs as per can instructions.
Thanks.

I've been using it for many years with zero issues. My routine is to add a full can to a full tank of gas every time I do an oil change. It was exceptionally helpful when it came time to change the plugs on my 3-valve.

This was my routine exactly. No issues.

Have used it a few times on different cars. Ran some through the crankcase of my fox and a old crv.. it had the oil looking a lot cleaner. Ran a couple of cans through the gas tank... can’t say it did anything.

My 50hp 2stroke Mercury outboard gets a can in the gas tank throughout the summer.

OK, thanks just looking to keep things squeaky clean, so I'll just add a can to the oil and gas. Did you get any noticeable smoking when added to the gas?

It doesn't smoke when added to the fuel tank

Suggest not adding to crankcase unless used as a flush to help with a sludge build up and then idle only, don't drive.

Thanks that is a very important point. Thanks.

why no smoke show?

With the exception of GDI engines which are known for having carbon build up issues. If you have been using Top Tier gas that is already formulated with all the detergents needed to keep your fuel system in optimal condition. Is there really a need to use fuel injector cleaner?
