Well, I'll see if I can play with it this weekend... It's looking to be a bit wet, and I don't have a way to get the car into the garage... so we'll see...
Refilled today and looks like I got 45.3mpg on the last tank... not too surprising that it was lower... I had to smog it, and since the smog place is less than 2 miles from my house, I drove around a bit prior to my appt to make sure I warmed up everything sufficiently... wasn't really thinking FE during the drive... and then they let the Maus idle for another half hour at least as they fiddled with the smog machine
