I've been tracking my flex-fuel usage - mostly E85 fillips - for a while now, tracking price and MPG. At least with the prices I've been getting, I typically get around 15% less MPG, but the price is between 10-15% cheaper. My 'cents per mile' price has generally remained the same over the last year or so I've been tracking (been tracking longer than a year, but have been using E85 more regularly in the last year).
Now... I've got a small car/engine. The MPG might be markedly worse on a bigger car. Don't know. But at least in my case, cents/mile is about the same.
- Scoundreller 4y agoSo then do you fill up with E0 or E10 so you can fill up less frequently?
- mgkimsal 4y agoLast... year or so I've been getting E85 when possible/convenient, and defaulting to regular 87 octane when E85 isn't available. Those tend to be the only reliably available options - haven't seen E10 around here. Last 6 months have been about 80% E85 and 20% 87 regular.
- BenjiWiebe 4y agoIn the US anyways, E10 is the regular gas. E0 (ethanol-free) is usually marked as being ethanol-free.
- mgkimsal 4y agoCan't edit now, so I'll add. With my typical city/town driving, I get 32-35 mpg with 87 octane, and typically 26-30 with E85. Regular 87 octane is $3.12 around me here, and E85 is $2.71. E85 works out around 12% cheaper.
