I heard they got out of commercial truck engines simply because of emissions standards. During the last few years they made truck engines, they chose to pay fines rather than meet emissions standards.
agreed 100% New diesel engines run fine with it. In fact it's not "Low-Sulfur" any longer. My Freightshaker requires "Ultra-Low Sulfur" (15ppm or less) Low-Sulfur is 500ppm or less. Runs fine. All newer diesel engines run fine with it. Said that Low sulfur diesel fuel will damage the engine.
