First 230 miles I got 18 mpg on 87 octane from Shell. Hand calculated.
I was consciously driving to conserve fuel:
- tried to never get the RPM above 2000
- coast to stoplights and stopped cars
- always try to keep moving when legally possible
- drove 65 mph on the interstate. I rarely got above 70 mph, only when traffic forced me
- easy on the acceleration
I'm aware of others around and I keep up at stoplights so the green light doesn't turn red because I'm being slow, but I didn't gun it off the line either.
My drive is 50/50 interstate and stop-and-go rush hour traffic.
I'm pretty happy with that. I was expecting 17 and got 18. For the next fill-up, I might try my normal driving style which is moderately aggressive to see what I get.
Next 250 miles I got 16.4 mpg on 87 octane from Sam's Club. Hand calculated.
I drove as I normally do. That is
- I don't gun it at stop lights, but I do accelerate steadily.
- I don't coast as much up to stops
- I keep normal distances to the car in front of me.
- I don't get over 70 mph much.
- Tach will get over 2000 rpm, but not much
There was more bumper-to-bumper traffic with this fill-up due to road construction during the morning commute. I probably spent 10 extra minutes in stop-and-go traffic a day from it.
