[QUOTE="rsr911, post: 3840, member: 452"] more.... BTU Values in BTU per gallon: No. 2 fuel oil (diesel): 138,500 Btu's per gallon. Flash Point 143F and Autoignition at 410F. No. 6 fuel oil (used motor oil): 153,000 Btu's per gallon. Flash Point 400-500F Autoignition 500-700F Biodiesel – Waste vegetable oil 120,000 Btu/gal. Flash Point 300F. Autoignition ? Gasoline 125,000 Btu/gal. Flash Point -45F. Autoignition at 495F. Hydraulic Oil ?Btu/gal. Flash Point 414F Autoignition 650F Transformer Oil ?Btu/gal. Flash Point 300F. Autoignition 482F. Environmental impact: While this will likely always be up for debate the "Green perspective" per a member of the Green Party who posts here (drcampbell) is that running WMO in a diesel engine is about the same as running diesel. My take on that is they both pollute roughly the same. Furthermore very little WMO is re-refined into usable motor oil, approximately 14%. The bulk of used oil is burned in some fashion either for heat or for power generation. Bunker fuel used to power large diesel engines such as ocean going vessels often contains used motor oil. Depending upon viscosity and purity used WMO can be classified as #4-#6 fuel oil. However one must consider the energy required to recycle oil, even into plain oil bunker oil. First it has to be drained and collected then driven to a collection center (using fuel to get there) from there is must be processed and again transported to the location it will be ultimately used. There may even be some transportation in between. All the while burning diesel or gasoline to transport it and using electricity to process it. My guess is that it's likely less of an impact to run it in your personal truck that have it converted to bunker fuels. Finally I have had to hear people tell me over and over again that WMO or WVO will ruin my engine, coke the rings, fry the injectors etc. From my perspective this simply is not true. I recently had a head gasket let go on my 6.9 engine. I happened to have the 7.3 engine from my old van sitting on a pallet and figured if I was going to do a gasket job I might as well do the entire engine and install the 7.3 due to it's larger head bolts which work better with my aftermarket turbo. At the time the engine had at least 30k miles running waste oils. I ran WVO blends in the summer and WMO/D2 blend in the winter. Upon tear down I was SHOCKED at how little carbon there was inside the cylinders, how clean the valves were etc. The injectors were replaced before I bought the van so I have no idea how many miles are on them. The IP was also worn when I got it. After a junkyard pump failed on D2 I put in an ebay rebuild which also failed in short order. I then installed a quality rebuild [url]www.mwfi.com[/url] and have put about 35k miles in total on that pump running waste oils 90% of the time. If I had to guess total miles on WMO blends I would figure about 20k miles in total as I ran about 5-6 months of the year on 50/50 WMO/D2 prior to switching to just W85. The truck starts in cold weather and runs great with plenty of power and almost zero smoke except at cold start up and heavy acceleration (IP turned up). The amount of smoke appears to be the same whether I'm running D2 or W85. Since I have now saved more than enough money to REBUILD the entire engine I'm not gonna even bother listening to people who swear I will ruin my engine. If on the odd chance it does wear out I'll just rebuild it or buy a junkyard engine with the money I have saved. By my estimation I have saved close to $6000 running waste oils in this engine alone. That is including paying for my waste oil, cost of filters and my setup, the thinning agent (D2 or RUG), and little things like disposable gloves and paper towels for cleanup. [/QUOTE]
