I think either product will work fine. I've used sta-bil forever in EFI as well as carbed stuff, and never had any problems. I now use the marine/ethanol formula sta-bil. Why sta-bil over sea foam? It's cheaper, I'm a tight wad, and sta-bil has given me no reason to want to change.

 

I use Sta-Bil or Sea Foam in my EFI bikes and vintage car. Both work well. Never had a problem.

 

I use Marine STA-BIL for all my engines that have a storage period. The Marine Sta-BIL is also cheaper than the original (red) STA-BIL. The small container of the Red version only treats 20 gal. of fuel, where the same size container of the Green Sta-BIL treats 80 gal. of fuel. Even though the green costs a bit more, it treats 4 times as much. Plus, it stabilizes the ethanol if you happen to have blended fuel.

 

Its listed as Marine grade Stabil. Thats what I use. My bike is usually put up for 6 months except for the odd year here in Vermont. I've never had a fuel related issue carb or Injected.

 

Geeze...why would you need a Gallon?? I've never even seen it sold in this area in a Gallon container. I think the cans I buy are 16 ounces. I rarely use the stuff in my cages. One can a year will usually get me through

 

I have not used Stabil for at least 15 years and definetly not knocking it. Stabil is a good product.

I did send an email to Seafoam asking if there was any alcohol in their product.. I says right on the can that Seafoam is a 100% pure petroleum product.

The response from Seafoam.

"Sea Foam uses propanol for moisture control. Propanol is a petroleum distillate."

Propanol is an alcohol and is not a petroleum distillate.

Like others have already said: propanol IS alcohol.
You can easily do the sniff test yourself. Just open a bottle of isopropal alcohol (that nearly every household in America has in their medicine cabinet) and smell it. Then very simply go and do the same with a can of SeaFoam. Make note of the similarities in the odors of both. The alcohol odor should be the very first thing you notice when opening SeaFoam, it's that strong an odor.

For the record I have used both products for fuel stabilization with equal results - both work well with zero negative effects for carbs or EFI.
I use mostly StaBil now because I don't see the point in adding even more alcohol to the 10% fuel I already have. Current ethanol fuels need no moisture control - they already have it. I regard StaBil as 'SeaFoam without the alcohol'.
