I was really bored and had a full tank of E85 in my car. So, i decided to see how many miles i can go if i baby the car. I drove from West LA to Willow Springs and drove back home and then some trying to maintain 70MPH and staying off boost (my gps says i did 67MPH avg) . The drive to Willow Springs, once you get on the 14N, is a LOT of long uphill highways. So, i was probably boosting anywhere fromn 0-5psi on the long uphill stretches. However, on the way home it was a lot of downhill driving.
I drove until my fuel light came on and drove for 10 about more minutes (245 miles on trip) and i filled up my tank with gas again (12.1 gallons).
According to my fuzzy math
245 miles / 12.1 gallons gas added to tank = 20.24MPG
I probably could've squeezed more MPG if i picked some flatter roads to drive on...and yes i really do need a life

I'm around 17 in mixed driving, 19 on hwy and around 12-14 if I am driving it like I stole it all the time.
I did get 21 once on a full tank on 100% hwy. I was testing out some seriously lean cruise and "do not try this at home" ignition timing.

I put E85 back in since its warming up in the north east and I got 21.5mpg last tank. Narrowband front O2 and normal ignition timing in effect. I was even hauling 100 pounds of stuff and did a couple pulls on the highway entrance ramps for good measure.
Was that with some pump left in the tank? I always get way better mileage on that one tank with just a little pump left. The next tank or third tank with 100% E85 the mileage drops.
