Non-Oxy gas in my truck?

[SkunkedAgain]

I thought that I remembered reading at the pump that you're not supposed to put non-oxy gas into your vehicles unless it calls for it.

I use the non-oxy, higher-octane in my snowmobile and chainsaws. I usually take up a big can of it and if I don't use it all, dump it into my truck's gas tank for the drive home.

Do they tell you not to put it in your vehicle's tank for pollution issues or engine issues?

Although Bobs experience is not unheard of, its most often not the norm. I personally wont use fuel more than a year old, but for some reason I cant seem to keep it around that long anyway. The amount of spoiled fuel problems, especially found on small engines has skyrocketed it recent years.

The length of time that fuel lasts varies greatly and is most affected by storage methods and temperature. The three month time period often cited, is basically the amount of time it takes before fuel will no longer meet its specification perameters. That doesn't mean the fuel is completely no good or unusable, just that it wont perform as it would in its original state. All fuel begins to degrade as soon as it is refined, but because of the alcohol content, ethanol fuels just do it faster. Ethanol gas can absorb 50 times more water than non ethanol gasoline. The less it is subject to temperature variations and air/humidity the longer it will be usable. A tightly sealed container in a dry, shaded, or temperature consistent place will keep gasoline useable for the longest time.

What do you mean by "much?"

Pulling 2 wheelers with my ranger, I got over 2mpg better with the non oxy gas in the tank.

macgyver, do you have any idea how long fuel will last with sea-foam?

[Macgyver55]

There are so many variables involved I dont think anyone could set a specific time. Generally SeaFoam will extend the life of fuel to a point but will not bring back fuel that is already degraded. It depends on if it were totally fresh gas to start with, if it was stored in a good airtight container, in warm or cool spot, and so on. Like I said earlier, treated or not I try not to let it sit more than a year without using it. You could go longer and possibly be ok, but in a two stroke it would be the more risky due to the possibly of (pre) detonation.

I suppose I could be just flirting with problems but so far I've been okay...or...lucky.
