I'm 29, ever since I was 15 I've used 93 in all my engines. (Chevy S-10, Silverado, Equinox,Cavalier/Pontiac G-6, Infiniti G35, Ford Focus) I have never had an issue.
With those temperatures Eddy its really a shame you can't find some 93 octane fuel anywhere. Doing octane/ethanol content testing I found 91E0(no ethanol) performance was poor anything above 82F outside. Switching to 93E10 I have much better power below 2500rpm in the 82-100F temps I have seen with the cruze.I'm using 91 because 93 isn't sold here and I saw the video from the GM VP talking about the need for Premium fuel in the Turbo CRUZE. I was also told the CRUZE would run cooler and its been 115 this Week, cooling down to 86 at night. I cracked my last tiny engine out here in the heat and this one is even smaller?
Mojave, mo problems, amirite? :smileystooges:I think there is Sunoco racing fuel available which is 95 octane, thought it was 103 octane but its $7.19 a gallon. the problem I have out here and no it is not humid is the cost factor between 87, 89, and 91. 91 is 40 cents more a gallon, that's a lot as the grade difference used to be less than a dime in the old days. 2001 was a great year, 99 cent Gas and that was after the TERROR!
Yes, 100% gasoline works better than 10% ethanol blends. But I never got mpg increases as high as you did!! My 3 previous cars got 8% to 5%(3 to 2mpg) better mpg, but not 6mpg better. My present Hyundai Elantra is getting ~ 3 to 2.5mpg better than ethanol blends.I use whichever one has no ethanol in it......91(octane), 93..... LS 1.8....it runs 1l/100km less (6 MPG better) than regular gas, which around here contains 10% ethanol. We still have my wife's Cruze, a LT 1.4T, and she's been doing the same.
B20 still has an energy advantage over E10 gas. Besides 10% ethanol fuel runs so much smoother in the cruze than 100% gas & from my testing & has no where near the improvement in MPG as Aburnet85 or Litesong claim. Gas turbo engines love octane AND ETHANOL!!!!he biofuel industry is lobbying hard to make less efficient bio-diesel (B20) mandatory just as they did E10.
