Higher speed not as bad as I thought

[mrmad]

I have been trying to keep the speed to around 65mph, which on I-15 north of San Diego, means I'm getting run over and pushed into the two slow lanes with the semi's, which are their own hazard.

Since getting gas at the same station for the last 5 or 6 tanks, I have managed to get my tank mileage pretty much near my average, so I'm reasonably confident in the mileage figures.

After a minor emergency at home meant I pushed the CRX home at over 85mph on one of the 45 mile legs of my commute didn't seem to effect my mileage, I thought I'd try raising the average speed from 65 to 75 to see how bad it would effect the mileage. Surprisingly, it didn't seem to effect it that much. The five tanks before this averaged 43.46, and this one was 42.50.

I'm going to try it for the next couple tanks to see if the average stays somewhere around 43. The extra speed shaves a few minutes off the commute, but more importantly, gets me out of the first two slow lanes and into the third lane where I don't have to worry about the semi's and the merging traffic.
