Theres a new Sunoco station that just opened up around me and there selling 85 octane for $2.99 a gallon (compared to 87 i use for $4.27). I have a 2.2 so im thinking i might be able to get away with using 85. I always used 87 but do you guys think there is that big a difference between the two? Also if worse comes to worse and i hear some ticking or knocking in the engine b/c of using a low octane, i could just put some 87 or even 89 to even out the gas at 86-87, do you guys know if its alright to mix two different octanes?

I say no!

85 octane or is it E85? You don't want to put E85 in your car...

although i would kill for gas that cheep!!!!!!

hm, not 100% sure since i havent gone to it yet, just passed it a few times and saw on the sign 85: $2.99...Ill go on Monday when i have to fill up and ill find out for sure.

its more then likely e85, there is a way to convert your car to run off it

EXACTLY WHAT I WAS GONNA SAY

Its fine to mix different octanes, but why do they even have 85? I've never even seen it below 87. I'd be skeptical.

It's E85.

just use sugar

It's gotta be E85... if 85 octane was THAT cheap, they'd mix it with 89 and be selling 87 for $3.50 and raking in the money.

89 is just 87 mixed with a lesser amount of 93. Some stations only have 2 tanks and it mixes right in the pump.

And some sell the same gas as 87 and 89. My point was if there was any way they could sell 85 for $2.99 they'd just mix it with a higher octane and make 87 to sell far cheaper than anybody else. I don't think there's any way they're selling anything other than E85 for 2.99 a gallon.

its 100% E85

don't run it if your car isn't E85 compatible

It's definitely E85, stay far away.

At higher altitudes they sell 85 instead of 87.
