I nearly passed out when I calculated my mileage today after returning from a trip to a nearby city. I gassed up before I left and cleared the trip meters (both A and B) with the express intent of checking my mileage. When I returned, both trip meters read 142.5 miles. I filled the tank with 1.274 gallons. (I was so stunned that I continued filling. After wiping the overflow gas from the car, I looked again. The pump read 1.288 gallons. By my calculations, that rounds to 111 mpg.
The air temperature was in the mid 80's. Nearly all of this distance was on interstate at around 79-80 mph (don't tell the cops) with a couple of slower areas where they're doing some paving work.
My husband still doesn't believe me. Can anyone out there back me up on this?
