What octane does everyone use for a 6.2 gas?

 

87 for the most part. Now & then if they're predicting below zero temps I'll fill it with 91 non ethanol.

 

87, towing or not.

flex fuel gets real bad mileage.

 

87, no benefit from higher

 

I run 89 octane.

 

No gain from running higher than 87, so why spend the money. As said above, flex fuel is for the crows.

 

87


Like everyone said there is no gain going up in octane.

 

Thanks to all!

 

87, but Top Tier.

 

87 is what all the mechanics I know have always recommended. The only things you use the high octane in is boat motors and lawn equipment because it's the only way you can get ethanol free gas for them here.

 

86 is the lowest, 87 most of the time. If the they don't have those I'll use 89 till the next fill up when traveling through the states.

 

Just curious I've never seen a station offering Flex Fuel what is the cost saving per gal. All the Gas here has 10% ethanol and I wish they would get rid of it I have to put high octane in my antique car because it can damage rubber lines.

 

87 ethanol free, every tank since brand new.

 

I use 87 and around here it's all 10% ethanol. I tried 92 octane once and did'nt notice any kind of improvement.

 

I live in western Pennsylvania & the only gas station Ive ever found the flexfuel at is at our Sheetz gas stations & not all of them carry it but the ones that do carry it youll notice a yellow colored hose at the pump & thats your flexfuel. The only benefit of flexfuel imo is its typically .20 to .30¢ cheaper than whatever 87 is but as far as performance benefits, I dont see any in my experience with it.
