OMG YES! Add fuel conditioner with EVERY tank of fuel you buy.
Do you know when your not going to be using your boat and it just sits? And how long will it sit?
Yea....I know....these seem like Dumb questions.....But the truth of the matter is you do not know......Life has a way of getting in the way of boating.
Job takes you out of town all of a sudden----Family emergency-----You get sick or injured.
You have no idea when these will happen, I hope they don't.....You say....it's only gonna be a month...and turns into 3 months.
Fuel separation starts in 30 days....along with that octane levels drop.
So if your engine says it requires min of 87 Octane...and you put 87 Octane in it and let it sit for 30 days.....It's no longer 87 Octane.....It's less than the requirements and that is not good for your engine.
Always run Non Ethanol fuel if you can.
Ethanol-free gas stations in the U.S. and Canada
I run 91 Octane Non Ethanol in everything I own. The vehicles do not get the stabilizer, because they get used constantly.
The gas cans get stabilizer in them....Used for small engines and use to be sometimes put in the boat also.
I run this as a Stabilizer...
Shop repair costs have exceeded $100hr....Fuel problems are probably the #1 cause of need a shop.....[usually because the boat has sat] How much stabilizer can you buy for 1hr of repair?......Never mind the aggravition and runing your planed outing.
