51.1 Miles on a Single Gallon

Red Crown Gasoline Gives 51.1 Miles on a Single Gallon Red Crown –

Cresco Plain Dealer, 1917

On Friday, July 13th, a Franklin touring car carrying 4 passengers. circled the Chicago Boulevards for 51.1 miles on a measured gallon of Red Crown Gasoline.

The test was made under the observation of Daniel Roesch, Associate Professor of Gas Engineering at the Armour Institute of Technology. Professor Roesch purchased the gasoline from a local garage to make sure that it was the usual commercial variety, and he personally poured the gasoline into an inverted glass container fastened to the running board and connected with the carburetor.

This test established a world’s record for mile age. True, the Franklin car is economical in its use of gasoline, and the driver probably was most skillful, but the Red Crown Gasoline used was exactly the same as the Red Crown Gasoline you buy at the filling stations or garages listed below, or anywhere else. Red Crown is always the same, no matter where you get it. The secret is in the range and. adjustment of boiling point fractions, scientifically. accurate.

Its funny how physics doesnt change when it comes to mileage in a vehicle

...physics doesnt change when it comes to mileage in a vehicle

Some twenty plus years ago, Bosch/VW could achieve something like 80mpg plus, with a gasoline injection system...problem was, they couldn't design a high pressure injector pump to last very long....gasoline has no lubrication qualities to it.

Here might be the next tech, if electric vehicles are slow to adopt

Is the Era of the Camless Valvetrain Finally Upon us?

"As installed on a Chinese Qoros 1.6-liter 16-valve I-4 engine, the Freevalve system lowers the engine height by 1.9 inches, length by 2.7 inches, and mass by 44 pounds. Perhaps more important, the engine’s power improved by 45 percent, torque by 47 percent, and fuel consumption by about 14 percent (at steady highway speeds). Official fuel consumption is expected to mirror that of a similar diesel but at lower incremental cost. Development of Qoros’ “Qamfree” engine should conclude late this year with production following shortly thereafter. Another 15 manufacturers have expressed interest in the concept."
