How to check to see if gasoline is still good?

[TrevorM]

It’s starting to get warm out and we all know what that means! So I am getting my Seadoo ready for the water after being winterized. During the winterization process I filled my tank up with premium 91 and added stabil marine 360. I am here to ask how to tell if the gasoline is still good after being stored for 8 months. Stabil Marine 360 (blue stuff) claims to keep gasoline good for 12 months.

But for some reason I’m concerned my gasoline isn’t the best of quality because I got it from Casey’s General Store and someone told me that Casey’s isn’t “top tier” and it goes bad faster? I never even knew what “top tier” gasoline was... I thought gasoline was gasoline. Also I see tons of boats and other PWCs get their gasoline from this Casey’s all the time. Anyways during the storage process I read the Stabile Marine 360 instructions carefully and it says you can safely double dose the gasoline to ensure storage of gasoline stays fresh so I actually added a little more Stabil than what’s required. I also add the Stabil Marine 360 to every fill up. Any thoughts? Should my gasoline still be good?

Your gas will be perfectly fine.

That’s a relief to hear! Premium 91 isn’t cheap! Also a little off topic but last summer I changed my fuel lines and rebuilt carbs but after doing so I don’t get much pressure from the fuel tank anymore. Like when I first got the Seadoo when I opened the gas cap it would have so much pressure it would almost shoot out of your hands, but now I open the gas cap and no pressure. Is that bad? I mean last summer the Seadoo ran good hitting 55mph after new fuel lines and carb rebuild.

Check your hose clamps but gasoline expands when it gets warm or hot. My guess it was just warmer then,.
