Fuel oil

thats all i use in my old Cats--just make sure its filtered good and I add power service to it also

Very interesting! We have an above ground tank at the grand folks farm with about 100 gallons of heating oil in it. This is pretty old oil. Would it be ok to run in the D2?

i would put some of the real old fuel in a clear glass jar and compare its color and clarity to that of fresh fuel oil---look for algae and impurities---i have never used fuel oil that is more than 3 years old

When my ex-BIL was running a vac truck, he got called to pump out underground tanks at old service stations. He reclaimed some of the nastiest old Diesel you can imagine. ..separated the water out, & ran it through a filter. He burned it in his trucks, a Mack & a Cummins, never had a problem, other than maybe a little more smoke. Algea would be the biggest concern, that will plug filters faster than you can change them...

Hi, Folks.
My understanding is that the older Cat engines were designed to be run on #2 burner fuel or similar, right up until the late 50s/early60s, when they started building high speed engines.

Just my 0.02.

My old mate Joe Camilleri up in Innisfail said many of the Cats up there ran bunker oil and it was sold by weight, not volume, he said it was stronger burning than diesel (slower burning I assume), he said if a D2 or D4 pulled a disc in 2nd gear with diesel it would pull the same disc in third gear burning bunker oil.

Hi, Mike M.
My second job after I left school sometimes involved running a 2T series D4 either plowing or bulldozing. The owner switched to using #2 burner fuel and it picked up some power then too.

Is there supposed to be a difference between heating oil and diesel fuel. I have always known #2 furnace fuel and #2 diesel fuel to be the same thing except for the dye and the tax. They come out of the same bulk tank here.

"Bunker" oil is heavier than #2. Dad drove semi hauling bulk petroleum for his whole career and they hauled from #1 and #2 diesel all the way up to #5 bunker fuel. The number 4 and 5 had to be hauled hot in insulated trailers and the institiutes that burned it in the boilers kept them hot so they would flow to inject in the boilers. Bunker oil was cheap and lots of BTUs per gallon.

I think it depends on the distributor--here on Long Island my guy says its definitely different refining of the fuels, but in Mass it comes from the same storage tank with different dyes added.
