Ethanol becomes a problem when it is not used quickly. If you store gasoline in a container, you should consider using an additive. I posted on this a while back, my ATV's started to run poorly. My Yamaha dealer confirmed that gasoline containing ethanol has become a huge problem for such equipment. Needles and valves on the carbs are being destroyed by the corrosive nature of Ethanol. Same with boats where the gasoline has a tendency to stay in the tank a bit longer.

This is true of MTBE oxygenated or non-oxygenated fuel too. Old, untreated gasoline will act like a varnish on the engine and coat everything including valves. This is not isolated to ethanol fuel. This is why boats, snow throwers, and lawn mowers should always be stored for dormant months without fuel or with treated fuel.

Ethanol corrodes what material?

My point wasn't that the previous poster was off topic, but that they were making an impossible recommendation, to go just down the street to get non-additive gas. I actually asked at the Sunoco near me what was going on with the additive. Basically it is by county. In the metropolitan area where I live all gas at every station for a 30+ mile radius around the area will have ethanol. To get untreated gas I would have to drive further away from town. The closest place he could think of was about 15 miles further West from me (and I already live at the far Western end of the metro area).

Evidently In my area its different that is why I posted, "down the block", just about all Gulf stations have the 10% ethenol but all the other stations no matter what brand have 0%.

I wouldn't worry too much about it. First, your car is fairly new so there aren't a lot of old deposits to be loosened by the ethanol. Second, a boat's fuel system and a car's, especially in the emission-conscious US, are much different, cars being tighter with regards to exposure to outside air and systems to burn off fumes, etc. Third, unless you refuel in torrential rain or leave your gas cap off you're never going to get that much water in your system. If the fuel absorbs it and takes it into the engine so much the better - it won't be there in the tank and lines to corrode or freeze. Finally, a little water in the fuel isn't necessarily a bad thing. Supercharged, high power, high octane aircraft engines spray it in to increase power by eliminating detonation (ADI). Recommendation - drive fast and burn lots of fuel.

If the station that you are using doen't have a filtration system to remove condensation from the gas before it gets to your gas tank and you live in the colder part of the country you could have trouble.Thats why they sell gas line anti freeze to prevent any problems in most cases.

Now way that wather has ever done any good for any normal engine!


Racing is a totally differant story!

The needle valve on the carb was destroyed, not stuck from the varnishing effect of old gasoline.

I live near NYC where you have to be skeptical of everything. But the chicks are hot.
