Why You Should Run Good Fuel & Sta-Bil


Bake's Marine

Recommended Posts

I haven't posted anything on the crew for awhile but felt this was worthwhile to share with you so you could see the importance of quality fuel and using sta-bil in your fuel. If this photo below is not proof enough why you should run good fuel (89 octane+) and sta-bil in your fuel system, I don't know what is.

The photo is a fuel rail mounted fuel regulator off of a 2004 Indmar LQ9, with 300 hours... You know how bad the regulator looks now so now you know how bad the rest of the fuel system (anti-siphon, pump, fuel lines, fuel rails, injectors, etc) is going to look and you can't just fix one with out fixing the others.

Complaint was "hard starting, no performance" Customer had only ran 87 octane fuel and has never winterized or ran sta-bil for the life of the boat (original owner). Just parked in the garage and felt that was good enough for winter lay up.

Nice. I can understand how a good fuel stabilizer would help that situation. But what would higher octane fuel do for it? Maybe because it has different additives that could prevent the buildup?

Thanks Paul.

+1 -- isn't octane rating just a description of the fuel's tendency to burn in a controlled manner?

I assume this philosophy would apply to just about everything with gas in it that "sits" for more than 30 days, or is exposed to moisture.

I think of things such lawn mowers/garden tractors, generators, chainsaws, etc.

I have a bad habit of storing those away for winter and not use stabil or even come close to winterizing them. :lazy::whistle:

I could be wrong but, what I'm seeing is excessive water in the gas, no?

Right on. That looks like moisture to me. Octane would have no effect on that at all. Lower than necessary octane woud cause detonation and internal damage.

Sure looks like ethanol in fuel is working great. :Doh: Paul is right about the Stabil...it will help keep fuels with ethanol from having excessive moisture content, especially in the off season. Hope you get them back up and running soon!

Only the blue stuff. The pink stuff could gum up the innards.

I think it depends on the ethanol content of the gas you're using.

FYI - Last fall when I was preparing for winter lay-up, I emailed Gold Eagle to ask if the Marine formula was suitable for long-term storage. I had assumed it was, but nothing on the website would confirm it. Here was their response,

"Both our Marine Formula STA-BIL and our STA-BIL Ethanol Treatment have

some stabilizing qualities however for storage of 30 days or longer we

do recommend our STA-BIL Fuel Stabilizer.

Wow nice of them to let us know on the label. :loser:

Too funny. For years I have used the red fuel stabilizer in almost every gas engine I own; boat, bike, cart, lawn mower, weed eater, & snowblower. The one gas engine I own that I forgot to use it in, the chainsaw, doesn't run right now. Everything else typically runs fine, even after it's been sitting for weeks or months.

When the blue stuff came out & everyone got all gung ho about it, I figured I'd use up all the red, and then buy some blue to convert over. Guess that won't be happening. :Doh:
