  1. This is something I have done for ever . Every 4th Oil change . Complete 100% fill with Diesel Fuel . 15-20 minutes FAST idle . 1500-2000 rpm . IMPORTANT ! ZERO LOAD ! Simply operating . Diesel needs to get hot enough to Drain well . Allow to drain for an hour and then put in your Fresh Premium Oil and a New Filter . Doesn't affect longevity at all and DOES clean everything very well . NO LOAD DURING THE PROCESS .
