Fuel Saving Tips

10% Ethanol gas (Gasohol), Know your vehicle

Due to government mandate, a large percentage of the gas in the US contains up to 10% ethanol, which is very detrimental to fuel systems and engines not designed for it (Small engines, older vehicles). In my Geo 10% ethanol equals roughly 10% lower MPG vs real gas. My Tundra on the other hand (Flexfuel) has an almost un-noticeable difference between gas and gasohol(the fact that it's usually used for pulling/hauling may disguise the difference). In the Tundra E85 gets 20-30% less mpg and, per the owners manual, causes shorter oil change intervals. So for it to be viable it needs to be at least 30% cheaper than gas/gasohol.
