I would like to know what grade of gas you all are using and why. I filled up today with Ethanol 89 octane and thought about getting 87 octane but wasn't sure how good the car runs. I know it increases mpg a little. Can anyone give thoughts or opinions?

Well I used to put 87 octane in my 05 cavalier when I had it 2 years ago and I noticed it helped the mpg a little. Not by much but it did. I was going to fill my car up today with the 87 octane but then I was thinking.."Im not sure how well it will run for sure or if my mpg will increase or decrease". Can anyone tell me with their knowledge and/or experience, in comparison, which fuel burns the best to get better fuel economy? I want to see how much more mpg I can get out of my LT. I think right now, im getting 38-39 mpg going right at the speed limit=]

93 octane*.

*: Tuned, so I have to run premium, and premium around me is 93 octane.

I think all we have around here in iowa is octanes 87, 89, and 91. Havent came across any 93 yet

Yeah for sure...I usually only go to one gas station here in iowa...It makes it less convenient since im picky lol. I go ot Phillips 66. Idk why I only choose that...I guess its because I notice a the car run better on their 89 octane than places like caseys or kum n go gas. So now I only go to Phillips 66 =]. Anyone have a Phillips 66?

 

[chevycruze2012]

what??lol. Are you serious? That's insane. I know there isn't a whole lot of them around, but dang. I would of thought you guys would of come across one. What ironic about this gas station is here in Knoxville at mine for a gallon of 89 octane its 3.79 as of right now...in a town about 2 hours away north of me is another Phillips 66 and their gas for 89 octane ethanol is 3.49 a gallon. I think its apart of the casino and Indians own it so that would make perfect sense because Indians don't pay taxes lol.

 

[chevycruze2012]

Im afraid to ask what anyone else is paying for gas lol. Probably better than me

 

[chevycruze2012]

holy crap. I guess I do have it better to others lol. Hopefully at some point in time, these outrageous gas prices do down a lot more and stay down. This is BS. As long as I have a fuel efficient car, I wont complain too much. All I know is this 3.00 plus is stupid and got old quick lol.

I use 89 ethanol simply because its cheaper....not that I couldn't pay another 10 cents a gallon for the 87 octane, I just am so use to using 89. I have used it quite a few times when I had my 2005 cavalier like I mentioned earlier in this thread=]. I got acceptional gas mileage with 87 I thought. The car ran fine. Only thing now is id like to run 87 in mine but im not sure how well its going to run. I don't want it running like **** that's for sure. I have the 1.4L turbo...so if anyone has the same engine which I know a lot of cruzes do, can you tell me what works good for you based off your experiments? Worse case ill just keep using 89 ethanol. Some of you may not know this, but all 89 ethanol gas is made here in iowa from our local corn. When you pull up to the station next time, look at the 89 gas sticker......If it has a picture of a corn stock on it, that was made here in Iowa =]. I never had a problem with this gas ever, and only difference is the mpg difference between 89 and the other octane ratings and/or whatever else the differences are.
