Because the oil workers may have been going on strike, and gas prices were still not reflecting that possibility, I went ahead and filled up a little early, on Friday.
4.018 gallons of ethanol at $1.80 a gallon.
9.082 gallons of 87 octane at $1.70 a gallon.
Works out to be 27.99% ethanol and 91.9 octane.
The last tank finished at 22.5 mpg at 28 mph average speed.
Once again, there were some really frigid temps during this tank. It started a number of times after siting at work all day at temps in the low teens. Started without a problem every time.
