I’ve a couple small gas kicker outboard engines and a generator. I put ethanol free gas in all of them but curious about additives. I use the marine Stabil additive for the outboards but curious if it’s problematic to use this in the generator engine? Not sure the difference between marine (blue bottle) and non-marine (red bottle) Stabil. I just want to be able to use the same fuel cans - with additive- across these engines and curious if it makes any difference. Thanks for any help or if there are other suggestions I’m all ears

reason I’m asking because I don’t have any gas vehicles and can’t use old gas anywhere, just want to make it last longer for the small carb’d engines - they’re all 4 stroke

I used to use only the marine grade (blue) stabil and I don’t own a boat. Reason, well I can’t remember :rotflmao but I know I had one.

Once I found out it only keep gas good for a year and red is good for 2 years, I switched to red.

Personally, based on what fire departments do, I keep everything dry (run till it quits). Had a push mower sit 7 years and it fired on 4th or 5th pull once it got gas. I can see boat tanks being harder to keep empty.

To make a long post longer. Dads ‘79 only gets run every year or 2 when I am up there. I drive it the entire time I’m in SD. I keep the tank plumb full and red stabil mixed in. take the battery inside dads house. Never had a carb problem on that engine.

I have used the red label Staybil and I like Seafoam. I have not had engine problems since I started using it. But I also buy non ethanol gas also. It is not as good as the old leaded gas for long term storage however.

Nice I’d consider using seafoam as well, didn’t know red Stabil was good for 2 years. Seems they’re probably all the same for the most part..
