ARCO gas made me lose 5 mpg!?

TongMan · 10-23-2011, 08:41 PM

I've noticed much less mileage when I get 76 gas compared to Chevron gas. I reset the trip meter at every fill up and drive until the low gas light comes on. With Chevron gas, I would get close to 340 miles before the lights come on. With 76 gas, I would get just about 300 miles. Numbers are no exact, just off the top of my head.

I had a nightmare yesterday, i dreamt about filling my Z with 87 octane gas from Arco. True story..

wow.. i had no idea different types of gas made such a big difference in mileage o.O. kinda makes me want to test out this claim. but i'd say stick with cheveron and shell !!

I have not notice any difference in mpg's when using ARCO, Shell, Chevron?

Actually if the gas brand did make a mpg difference don't you think they would promote that.

Maybe I just got a particularly bad batch. I filled up with 76 after I got to half on that Arco tank a week ago and I am now back to a more normal mileage. 180 miles on a half tank vs less than 130 on the last one. I agree it seems to drastic of a difference to be the norm, but I'll still stay away from Arco from now on.

I've had mileage drop by 5-6, and I always get gas from the same place. I've always just wrote it off as a fluke.

Shell or Chevron unless I'm running on fumes.

did I accidentally click a link to a a prius forum?

Honestly though isn't this about the time that most gas stations switch over to "winter gas"? I thought winter blends of gasoline typically give lower mpg.
