1976 Dodge Dart Dart Lite Gas Mileage (Dart Lite) - EcoModder.com
I filled up Saturday afternoon.
I was no happy with results.
19.17 MPG (no correction factor for tire diameter difference of 3%)
My brother and I looked over underhood. PCV hose was unhooked, vacuum ports on carb had cracks, and the enitre carb was loose, the nuts had worked loose.
We cleaned up these hiccups, and adjusted idle down, and adjusted air fuel mixture screw for best idle. The car ran GREAT on the way home.
Sunday I checked oil and struck nothing. I park it over rocks, and I guess the leak is still significant. I swapped the valve cover gasket a while back, and it got better, but there must be something else. It was very low.
Ultimately, the MPG was very close to last time, and there were several factors counting against the MPG. With the vacuum leaks solved, idle and air fuel adjusted, plus full of oil, it should be a much happy camper.
