They do actually burn better than newspaper. The venting in the cloth makes for a cleaner more complete burn.Quote:

ahaha I know!
If the owner's manual does not specify that the car REQUIRES anything over 87 octane, then don't use anything above 87 octane.
'nuff said.
Some higher-end vehicles can only use premium ( like some Lexus's and Acura's), because they are designed for it. But any notion that premium gas will make an engine designed for 87 gas "run better" is simply psychological. ONLY use 87 octane! Don't waste your hard-earned money.
This may be an older topic, but i need to add my 2 cents LOL. When I run regular unleaded in my Aveo, I average 28mpg, (mostly city driving) when I run premium unleaded, I average 32mpg an extra 40 miles of driving to me is worth the $1.50 to $2.00 fill up difference. Back in the day, when I was a Lincoln Tech student, we had a homework assignment to go to a gas station and obtain a sample of gas, over the time frame of 2 weeks, everyones samples had a chance to settle. their were huge differences between Gas stations, most big names were better than smaller names. Im in Texas, we had several samples from multiple racetrac locations through out dallas and Fort Worth, from 6 or 7 racetrac samples, their were all about 35 percent water and all had debris floating in it.
Hey Paul I'm with you and going to throw a comment here on this ancient thread. I have noticed myself that even though premium is more expensive I do notice an increase of mpg. Typically my automatic gets 30 mpg with 87 octane. When I run 93 octane it increase to 33 mpg. I have done this several times just to make sure this wasnt a fluke.Quote:

it is likely the switch octanes of the crap you/we all call "gas" will increase mpg. But it is not the Octane change that increases fuel mileage. It is most like the amount of ethanol in the gas. You see those pumps that say up to 10%? well regular most likely has the 10%, where as premium might only have 8% Super might have 6% .(regional names? 87, 89, 91ish respectively). ethanol is not as fuel efficient as gas is. So if you run 100% true fuel, then the mpg wont change with octane changes. but the displacement of the ethanol will..
How ever at the same time you risk having unburned fuel into the exhaust, eventually clogging your cat and seizing the engine. You might pick up timing issues. The added octane does not burn the ethanol more efficiently.. its just there possibly is less there.
If you find a gas station that uses the same amount of ethanol in every grade of fuel. you will see the same fuel mileage.
The best thing to do would be find a filling station that does not add ethanol, and buy their 87 octane. It would probably provide the BEST fuel economy, but good luck with that i think when gas prices went over $3 a gallon, ethanol got put into everything.
