I've got nearly a full tank of non-ethanol 93 octane gasoline in the boat that is about a year and a half old. Should I pump this fuel out or can I get by with adding sea foam or some other conditioner to the fuel?

Did you treat it before you stored it? If not, I'd use it as yard equipment or junk car gas.
Sea foam is not designed to increase octane or increase "Stail" fuel. It is designed to treat engines and componants and treat fuel from going stail. It also does not remove water from fuel.
This is the same with Stahbil products. Fuel going bad or stail can result from many factors including but not limited to: what type of container it is stored in, environment to which it is stored, and environmental changes during the storage time.
Your ace in the hole is that it was NON E fuel!
If it was me, I would choose one of two options just to be safe.
My first option would be to pump all the fuel out of the system and use it in my vehicle, lawn and garden tractor, or other.
My second option (if you don't have one) would be to install an inline fuel/water seperator (10 micron) filter.
Remember, it is much cheaper to put new gas in the boat than it is to replace an entire motor! Without someone physically checking the fuel for it's current octane rating and fuel/water viscosity, I would pump it out and start over. I would ensure to add a Seafoam type product to my first tank to help clean any residue that might be in the lines, carbs, or fuel injection system.
burn it

EXCEPT my boat uses premix fuel and it doesn't help in 4 cycle engines. weed eater and chain saw can use it but they don't use much of it.
Good point.. I forgot about the pre-mix motors. Have not had to deal with them in quite awhile. It makes a good grass and weed killer!Quote:

If it's that old and never had any stabilizers added to it .... I'd pump it out and take it somewhere it can be properly disposed of, and not use it in anything. :twocents
What kind of motor do you have that requires 93 octane? Just curious
I don’t know much, but here is my one experience. I drove an hour one way last weekend to test a boat that I was considering purchasing. It had a 2001, 4 stroke Mercury 115, with only 350 hours. A shop had went through the motor and serviced it, to the tune of $1450 last April. Now for the problem. It had not been started since,with about two gallons of gas in the tank. Well, the motor wouldn’t start. We trolled to a marina gas pump, and unhooked from the bulb. We bled off about a half gallon of the most vile smelling, black gas with floating gunk! Tried 5 gallons of fresh, 93 octane. No go! Needless to say, I walked away from the deal! Take this for what it’s worth, but draining and refilling would definitely be cheaper than what this poor guy is going to have to pay...again!
trash it avoid the old gas in anything !!!
I would pump it out and start with fresh fuel for the season. I borrowed a portable pump from a local garage yesterday and pumped 10 gallons of old fuel out of tank; about 8 gals.into my old truck and the rest in a gas can. Then dumped a can of sea foam in the tank.
Best thing I have found as a additive to store gas for any length of time is called Star Tron in a blue bottle at Walmart or Auto Store. I have never had a problem for the past 10 yrs starting a 10k generator with this additive plus sea foam in it as well as all my other small motors besides my boat motor. Generator is only used when I have power outs. I put this stuff in every can of gas I also keep in the garage. Check it out even google it to read about it. It keeps gas fresh for up to 2 yrs is what it’s advertised to do.
Remove the old gas, run a good fuel treatment.
If you wouldn't use the gas in your boat, why would you use it in your vehicle? I'm not being sarcastic.
I think I can burn it in the ole truck with 8 cyl better than 3 cyl OB; it was regular non- ethanol treated with seafoam. Heck been doing this for years!
I would smell it first if it smell like normal gas I would run it, if it smells like varnish dump it.
