Luckily for me, I found a gas station that sells 10% ethanol blended 94 octane fuel for the SAME PRICE as regular on Thursdays. Not only am I paying $1.10/litre for 94 octane fuel, but it got me another 40-50km per tank over the 91 non blended I was using before.

I got my best gas mileage to date last week when I filled up in Syarcuse. Drove 300 miles and got 35mpg and I wasn't driving like a granny as much as I normally do. Who says NY gas is crap?

The entire tank actually carried me 830+kms.

I thought that E-85 was more expensive?

Yup, so true. 92+ octane nets me a good 40 mo+


re
miles to a tank than
91.

here'* a question, anyone notice a difference between 92, 93 and 94? I think you can only get 94 at shell, I've never used it

It'* not E-85. It'* normal gasoline blended with 10% ethanol. Think of it as E-10. Our cars would not run on E-85.

Between 91 and 94 I noticed a huge difference. Roughly, I think with each octane point increase you should see another 10km-15km off the tank.

EDIT: And if you're in Canada, check out Husky. On Thursdays you can get 94 Octane Premium Plus fuel for the price of regular. Not only that but you can enter codes online for prizes and stuff.

Actually, if I've read right, I think E-10 is our only option here in the states. That'* probably why our gas is a bit cheaper.

There'* a little mixup here......higher octane through Ethanol is known and proven to REDUCE fuel mileage slightly. The only way you could have gained from it is if you had significant KR to begin with.

I also see a difference between oxygenated and non-oxygenated 91-93 octane. The non-o2 being more money, but better performance.

E5 and E10 are not the only options in the States.

We use no Ethanol at all in Oregon. But CA uses either E5 or E10 depending on county.

The Ethanol blend creates a higher octane, but lower fuel economy. Nonetheless, the highest octane you can get in CA is 91 octane. This is why I tend to prefer driving my bone-stock L67 to CA rather than the Zilla. The Zilla has a thirst for Octane, even with the much less aggressive pulley sizes (2.5" or 2.2"). The 2.0" pulley in CA on 91 Octane E5 or E10 would kill me and my car.

If I'm doing a round-trip to Northern CA in EITHER car, I prefer to top off to a full tank in Ashland Oregon, in the hopes I can get back to Ashland on the return trip without having to fuel up anywhere in CA. With all the driving to and from the Chapel and Cemetery with my Family on this last trip, I failed to preserve any decent fuel, and ended up coming home with the 91 octane CA gas (unsure whether it was E5 or E10, but it was one of the two).
