33mpg in the city with a corolla is pretty good, was the car fully warmed up for these laps? I have noticed the first 20-30 mins of my drive, my instant mpg seems to go up, temp sensor is always the same, and intake temp slowly goes up as well. I made a warm air intake based on this, and it didn't effect much except on really hot days where intake temps got 120+ F.
Anyway, glad to see the elderly showing interest as well, they won't just go slow, they will get great mpg as well
