Non-0xygenated gasoline

[pisces]

My local Filling station recently started selling Non-oxygenated gasoline, about 10cents over premium price. says on the pump "for collector cars, cars eligible to be registered as collector cars, snowmobiles, motorcycles, boats, lawnmowers, and other small engines only".

The station owner told me it is great for anything that is not used on a regular basis, as it will not deteriorate as regular gas does. He said that for storage, as over winter, it is not necessary to add stabil or such.

Anyone know more, or can you confirm or deny the accuracy of thge stations comments? THANKS

All gas goes bad over time. Non-oxygenated just has a longer shelf life. I'd still use some stabil for storing for any appreciable amount of time.

Remember too that for best performance you should run an engine with gasoling rated at an octane that the manufucturer designed the engine to be run at. Many people mistakenly think that putting 92 octane gas in an engine designed for 87 or 88 octane will improve it's performance when in fact the opposite is true. The higher octane changes the running temperature which adversely affects performance. Good racers running stock engines will also tell you this. If, however, the engine was designed or modified for higher octane, then it is useful to use the higher octane. Some sleds come with a switch to select high octane or regular being used.
