Anyone with a late model diesel knows the nightmare of the Diesel Particulate Filter. DPFs are emission control devices designed to remove the soot or solid matter present in the exhaust gasses produced by diesel engines. The DPF is a device resembling a catalytic converter on a gasoline engine and employs similar technology. Exhaust gasses are passed through a honeycomb like matrix of passages, either constructed of metal or ceramic this core is susceptible to clogging.
According to Lucas, Extensive lab testing showed after just one tank of fuel with additive exhaust pressures were reduced, and 30-percent of particulate matter clogging the filter was gone. He recalled a particularly bad case; “[A] freight truck stopped up so bad it was regening everyday for 45 minutes. After a couple bottles it went back to regening every couple weeks.”
The Lucas Oil Diesel Deep Clean is available in 16 oz bottles (part # 10872) that treat up to 30 gallons for pickup trucks, and 1/2 gallon jugs (part # #10873) that treat up to 120 gallons for semi-trucks.

Here I was, thinking you didn't have diesel vehicles in America.

 

Most are p/u trucks: Cummins Dodge 5.9L & 6.7L have been around for a long time in p/u trucks, new 3.0L V6-ECO DIESEL in Dodge Ram & Jeep Cherokee, Chevy Duramax 6.6L in p/u, Ford PowerStroke 6L 6.4L & 7.3L in p/u. Toyota Tundra coming soon with smaller 5.0L Cummins Diesel.
Also VW, Mercedes have been around for ages in cars.
