Do any of you fine fellas have experience using old heating oil in a diesel engine? This fuel has been sitting in an underground tank for roughly 40 years. It is brown in color and somewhat dark. When rubbed between fingers feels more like light oil than like diesel fuel. From my narrow view into the tank, through 2" pipe, I see no slug on top of the fuel and can feel none in the fuel until about 3/4" from bottom. The tank is approximately 3/4 full. The fill cap and vent are both inside a storage shed, so have been protected from the elements over the years. Anywho, I just got a sample tonight from the tank, and I am wondering how to test it for bacteria, and if it is viable to use in my 12v Cummins. What say you all?
