Is there anything you can add to gasoline to kinda rejuvenate it, or make it more potent?

My '83 Honda Odyssey 250FL has been sitting in the shop unstarted with mix fuel in it since December. I started it tonight and it ran fine, but I think the gas could be better. I was gonna replace the fuel, but there's a lot in there. Can I add something to it to "juice it up"?

I don't mean something like Stabil, but maybe should I add some octane booster or something?

Adding anything may mess up the mix.

Try making a new mix and then drain the tank and mix the two "Mixes" together and use it. :-\\\\

Ugh... messy messy. The fuel isn't bad, it's burning just fine, if anything I think some of my gas may have evaporated off because even once the engine got good and warmed up it was still a little heavy on the smoke, so I might add a little fresh gas only, just a quart or less of fresh stuff.

Maybe just get one heat range hotter plug (or plugs) for it and run it all out and go back to stock. :-\\\\

I was going to be getting new plug(s) for it anyway, how do I get a hotter one? I usually just replace with the same plug(s).

Disclaimer: yes, the FL250 is a single cylinder, but the head makes provision for 2 spark plugs so if you are trail riding and you foul a plug, you just move the plug wire over to the other plug.

Just ask at the parts store for "One heat range hotter". I did for my weed wacker and got what I needed since I put a thicker mix.

Hotter plug will have a lower number on it. For example, BPR5ES would be "colder" than a BPR4ES.

Interesting. So will this be true for NGK? I might get one hot one, one normal one.

Yep. The numbers that I posted are NGK numbers, and I think they may be what the Zuk uses. ;D It was the first plug number that came to mind. ::) ;)

You're right about evap, butane is probably the first to do that because of it's low flash point.  Butane vapor is what you see coming out of the filler while gasing up. One of the worst things that gasoline does if it sits around too long is that it turns to varnish and gets gummy, sometimes Berrymans fuel additive will help cut the varnish if it isn't too bad. Best thing to do if you won't be running an engine for any length of time is to add a little fuel stablizer to the fuel.  I resently used some fuel I had in a five gallone can that I mixed in two ounces of Sta-bil more than two years ago and it smelled fresh,  Sta-bil claims it will help keep it good up to a year.

Dude, you don't want to know how many freakin' filter numbers I have memorized over the years. ::) :o I've had to memorize so many different brands due to working at different places, and other parts too. I'm glad to be back at the dealership. ;) ;D

It may be smoking more because the premix was starting to separate?
i'd just run it and change the plugs when this tank runs out.
