1970 Duster project in Sweden

Took my girlfriend on a road trip today. Only small country roads. We checked out three different castles and had dinner in the archipelago. The car drives great, it goes totally straight on the road, the temp gauge is nice and steady, breaks are nice and even and it is really nice with the new shocks up front and the new leaf springs out back. Gas mileage is 1.78 liters for 10 kilometers. I'm not sure how to convert it for you guys. A great day!

10km = 6.1 miles
1.78L = 0.46 gal

First, let's get the bottom to = 1. To do that, we take the 1/x of 0.46 and get 2.13; then multiply 0.46 * 2.13 to get 1 gallon. To equalize the rest of the expression, we multiply 2.13 * 6.1 and get a little over 13 mpg. Sounds about right for a warmed over 273 putting around town.
