I filled up Slambo after 195 miles of clean driving yesterday (knock wood, she's been running really well, the weather's been perfect, and the roads were clear). The fuel gauge was in the 3/4 range. I expected a meager 4.3 gallon fill (or thereabouts), based on careful instrumented driving.
The attendant (hey, it's jersey) pumped in
6.891 gallons.
This was my normal station (of late), but a different pump and grade (switching from regular to premium).
The '99 Civic HX has a 11.9 gallon tank.
Where did the extra 2.5+ gallons go?
Could the pump be that
wildly miscalibrated?
Note: I usually wait until below half full to refuel, but I wanted to have a full tank from my normal station before taking a trip up north this week.
