Scott Oncken is owner of Eco-Offroad LLC. He started playing with rusty old vehicles clear back in high school when his Chemistry teacher (owner of a 1946 Chevrolet truck) took him under his wing, or as his parents say, “corrupted him” to the ways of vintage vehicles.  As he began tearing various vehicles apart, he also started to explore cost-efficient ways of powering them while obtaining the best fuel mileage possible — thus the blooming interest in diesel engines.

While his previous academic background is in Criminology and he is a retired United States Capital Police officer, his passion for vintage vehicles has never died. That is why, in 2005, he pursued his true calling and went back to school to become a trained professional mechanic. He chose a vocational school that covered all the areas of mechanics: chassis fabrication, sheet metal repair, trim/upholster and diesel engines, helping him to transition from a back yard mechanic to a professional.

With the birth of his first son, he found himself further evaluating what type of future would lie ahead for his children. Scott has always been in love with the great outdoors and exploration, and wanted to find a way to be able to enjoy those surroundings with his family while at the same time limiting the footprint he left behind.  It was this idea that led him to start Eco-Offroad, LLC in 2008, to “recycle” an older unique suv/truck and make it environmentally friendly and drivable. Currently Eco-Offroad is focused on utilizing small Cummins diesel engines in vintage FJ45 Toyota Pickups and Series II Land Rovers. When these small engines are paired up with overdrive transmissions, they allow the vehicle to obtain 25 mpg; and with a little more playing, vehicles have been known to get better than 35 mpg while running on biodiesel and/or vegetable oil.

With our current changing environment, Scott believes it all goes back to what Rudolph Diesel, the inventor of the diesel engine, once wrote back in 1912:

“The use of vegetable oils for engine fuels may seem insignificant today, but such oils may become in the course of time as important as the petroleum and coal tar products of the present time.”
