plus gas or regular gas and kerosine?

[rdq]

I heard that using plus gas (89) will get better mpg and supposedly is better for the fuel line. Also regular gas (87) and 10% kerosene will give you performance like using premium gas (91).

Any experts on this?

Don't believe anything you hear and only half of what you read.

wellllll.... inducing kerosene WOULD slow the burn rate - rofl - but i would not care to try it! might poison the cat (then who/what would drink the milk?) and/or clog the injectors... anything might happen. and whatever experiments that take place will NOT be paid for by me!

yea i have never heard that before either and dont want to try it lol

Read your owner manual, it'll tell u what to do to take care of your car.... and fuel use.

i think it would be easier and cheaper to just buy the 91 octane and be done

Cars aren't really designed to drive on kerosine (I think). Most engines aren't really designed properly to be able to run on a mix of ethanol and gasoline. I know that simply changing from 87 to 91 octane really doesn't do anything for mpg. If it does, the average driver thinks, "Well I am getting better mpgs so I can be a little heavier on the gas" and they completely negate the benefits and possibly lower their mpg.

As for performance, 91 octane really doesn't do much for engines that are designed for 87 octane like the 1mz-fe. If I had a Jaguar I would use 91 octane and not 87. But I don't, so I don't.

If you want better performance, tape quarters to the bottoms of your shoe... you'll go a tad faster then.

If you want better fuel economy, let off the gas and coast more often. Don't have your foot on the gas if you know you're going to stop in a block or two, and don't jump off the line when you see green lights, just let your car roll for a second or two first then softly accelerate. People will think you're driving like a granny, but your wallet will think you're driving like a genius.

I recall the Avalon manual saying 89 or 91 is preferred, but 87 is acceptable.

I always put 91 in my car, for the "peace of miiindd" Mind over matter, right? haha.

I never saw it as that big of a deal, its 55 dollars to fill up the Avalon, and 57 dollars if you go with premium. Perhaps when gas was under two dollars a gallon that figure had more of an impact.

My mom has always used 89 when she had the Avalon, and I continue to do the same. It just seems right to use the middle grade. Since we have 93 octane instead of 91 down here, it's a little pricey.

my car doesn't care what fuel i use. it performs no better and gets no better mileage with premium, or shell v-power. it does respond well to my secret fuel enhancer... once i thought that stuff would make me rich. nobody believed me and everybody accused me of trying to rip them off. now noone will ever use it, except me.

i consistently get 27 in town and 31, on the interstate.

i always use 87 but i used to fill up at ampm and thought saving 10 cents a gallon was worth it till my car would start then die. theyre gas is crap so i only fill up at shell or mobil.
