Long stroke engine fuel mixture comment

Guys -- Several years ago, my uncle had a Ford pickup with the 300 6 cylinder engine in it. Having to drive many miles to the refinery where he worked, mileage was a big concern. Doing what he could to maintain good mileage, the best he was able to obtain was 19 mpg. He discussed this with a chemist at the refinery and he indicated that his engine was the last of one of the longer stroke engines on the market. Advised adding 1 quart of diesel fuel to every 5 gallons of gas during fill ups. Gasoline burns a little too quick to utilize the full power stroke. The diesel fuel slows the combustion from a "bang" too a "boom". His mileage increased to 21mpg with no abnormal effects. Sold the truck with 130,000 miles with no engine issues.

I have passed this on to several tractor owners with longer stroke engines (like the green tractor guys). This trick on one Deere made the difference in being to cut hay with the grass wet verses dry.

Wondering if anyone has ever tried this in their engines? I am going to try it out this summer on my F-20 and F-12, as our tractor show will have access to a Prony brake this summer to measure any changes.

Thoughts anyone ?
