stabil

I just use the blue stuff every tankful in anything that sits. Not cheap but works well. Prevents phase separation.

Bio'Kleen in diesel and Stanadyne fuel additive too.

NO.
Stabilizer and fuel system cleaner are not the same thing.

If you are fairly sure that you have bad gas, it should be removed.

If you think you need a fuel system cleaner, Berrymans B12 Chemtool, Gumout and Techron (for injected systems) are good.

If you are just taking a wild guess as to what the problem is......a multi-purpose fuel system cleaner might help you figure it out.

There are (a lot of) other things that will cause an engine to run poorly.

No...it preserves for about 2 years what ever gas is in. Not going to restore.

Real test for me was 2 year old gas in lawn mower and with stable. Doesn't take much bad gas in single cylinder to tell difference.

Use the blue marine grade stabil. It's a concentrate and lends itself well for the big RV tanks

I have used liquid "Heat" to dry moisture out of the gas tank. Otherwise, draining out the bad and replacing it with good gas should solve the problem

Stabill is a great product but used to stabilize gas that is going to be stored for a period of time.

No, you put it in fresh gas to keep it fresh through storage.
