Yes, it's been done before, but how about an update? I'll go first:
1970 914 w/'74-spec 2.0L D-Jetronic, stock w/Euro pistons, Crane XR-3000 ignition and Crane coil. City: 24 mpg / Highway: 39 mpg (flat road, 75 mph, 80 mile trip) What are you getting? The 914's a lot better than my '03 Boxster. |

Stock 1.7, Djet. Average: 23 MPG. Range: 15-30 MPG, with lots of variation. I've spent a lot of time trying to figure this out. I even correlated the number of days between refills and MPG for the tank across several thousand miles. My thinking was that gas was evaporating through the broken vacuum lines running from the fan to the charcoal canister, or some other unknown leak. Correlation was -.35 (more days between tanks = lower gas mileage). It's time to get those lines repaired and check again.
Any other ideas? |
