I'm new to Steel Soldiers, bur not new to the Deuce. I have three Deuces, a M105A2 trailer, five air shift spare transfer cases, a couple of those crappy sprague clutch transfer cases, six spare transmissions, and 4 engines in the big steel case, just in case I need parts.
Regarding WMO for fuel, I have been running pure WMO for the last 3,000 miles with no problems at all. I've run WATF about 2500 miles. I like it best. I ran Waste Cooking Oil for a while, but it's hard on my pumping system, unless you clean it after each use. YUK! And Laquer thinner or Acetone is about the best way to clean up the WVO, but its $15 a gallon. Plus when I'm running it, cats follow me around. So I got off of that and I'm sticking to the WMO and WATF.
I pump it into drums and store it until I need it. I use the 6HP clean water pump from Harbor Freight. I filter it coming in to the pump with a 100 micron metal mesh washable filter. Coming out of the pump I have two 30 micron Wix Oil filters, and a 10 micron canister type fuel filter. When I pump it out of the drums, it goes through the same filters again. I have had no problems doing it this way. I change the three outgoing filters after pumping about 150 to 200 gallons of oil. The primary fuel filter on my Deuce has gone the entire 3000 miles with no problem, and I just changed it this week. As for starting, I live in Louisiana and we don't see a lot of really cold weather. However, during the last week we had temps going down to 17 degrees. I hit the red button that morning and the Deuce cranked just like it does at 80 degrees. I was surprised, but very happy. I have begun running used ATF, and it is doing fine. I filter it the same way. I can upload a photo of my filter system if anyone wants to see it.
