Hey, I inherited a Polaris 800 Ranger, 2010 browning edition, in good shape but been sitting or 3 years, i had all the fluids changed and did a good service but what can I add to that first tank of fuel to clean those lines out, I THINK it is FI and not carb'd
thanks

Dilution is the solution. If the tank is less than half full, fill it and run it. If full, see if you can siphon a portion out and fill with fresh gas. If the motor is running fine, that is all you should need to do.

Always use Clear gas and/or fuel stabilizer in the off road equipment.

There may be a fuel injector cleaner you can add to the fuel, but don’t know what they are called anymore.

Best is fresh, marine grade mid octane non-ethanol fuel. some will say seafoam is good but it is really just naphtha (lighter fluid). this is 40 plus years of off-road riding and wrenching on bikes, quads, buggy, wave runners and trucks.

Personally, any gas that has sat in the tank for 6 months or longer on my bike gets siphoned out and dumped into one of my trucks at the next fill up. Perhaps overkill but I like my FJR running at peak power and efficiency.

Any fuel used with a small engine like a mower, chain saw, etc gets an additive to protect from the potential damage caused by ethanol laden gas.

Drain tank of any old gas and replace with fresh NON_ETHENOL gas and fuel stabilizer and after running motor for a decent time then add fresh gas to top off the tank. Also check out any and all fuel lines (especially rubber) , filters and fittings/connections to verify that they are in servicable condition ....................................... drill sgt.

I should have clarified fellas, the tank was ALMOST empty when I picked it up, I added new 93 octane fuel to top it off , I was more asking about it what additive would help with gummed up lines or whatever

As mentioned above, Sea Foam.

I run this stuff in my Can Am. It hasn’t sat for several years, but I add it to regular 87 octane each fill up.

I use Seafoam in the tank at the beginning of Fall and Spring, and Stabil in the gas cans. Premium gas only.

If it’s running fine, I wouldn’t do anything.

When things are gummed up, they run poorly.

thx fellas !

Im a little late to this but for something that has sat I use a healthy dose of Berrymans B12 then Seafoam in following tanks full.

StarTron is a really good fuel stabilizer. Seen it keep 5 year old fuel still good. Redline, Techron and BG44K are fantastic fuel system cleaners.
