The Trial Run
Brent Willsey, owner of Powerlabs Diesel in Idaho Falls, Idaho, and an avid diesel enthusiast, gave us some crucial food for thought on the matter. Willsey made a small investment in a pump and centrifuge system to clean up old waste oil and fuel his 1982 Chevrolet 6.2L diesel with the refined end product. His initial thought was to run Black Diesel in an old, worn-out truck as an experiment to see what all the hype was about. When Willsey bought the 6.2L, it was sitting at around 95,000 miles. Since he started running oil in the engine, he's placed another 6,000 miles on the seasoned truck. The results of this little do-it-yourself science experiment left him shocked. In fact, it worked so well in the old 6.2L Chevy that he decided to run it in something a bit newer. The next test was doing a 50/50 cut of oil and diesel fuel in his 2001 Duramax engine.
"A lot of people use two-stroke oil to add lubricity," Willsey grinned. "You put this stuff (Black Diesel) in that Duramax running 70 miles an hour down the highway at 2000 RPMs, that truck is so quiet and smooth, every once in a while I have to get on it to check if it's still running."
Willsey's modest $5000 investment in the Duramax-which already had 280,000 miles on the odometer-gave him peace of mind that if something were to happen, he wouldn't break the bank on his next Black Diesel trial run. As of today, Willsey still runs this oil/diesel fuel mix in his Duramax and has put nearly 10,000 miles on the engine this way. This may be a stroke of luck for one courageous driver, but the proof that it's possible seems to be there.
