Lots of opinions with little in the way of facts.
The practice of burning used diesel engine crankcase oil as fuel has been popular with fleet users for many years. The main caution is that the oil must not have been contaminated by coolant. The practice will not void the warranties of any of the major engine manufacturers. The lube oil is burned completely and, BTW, has a higher BTU content than fuel oil. The process should be done carefully in order not to "over oil" the fuel. Racor, the filter manufacturer, used to sell a system for the purpose. I bought several for a fleet of large EMD, Cummins, and CAT generators. The systems made us a lot of money by saving the cost of disposal of used lube oil and avoiding the cost of thousands of gallons of fuel oil. The Racor kits were in several sizes to accomodate small to large applications. I don't know if Racor continues to market the systems. Butch wrote in message oups.com...

But weren't these mostly mechanical fuel injection?

Bill,
I'm not sure I understand your question. But, all diesel fuel injection systems are mechanical. They are also hydraulic. New systems use digitial electronics to more perfectly control the hydraulic/mechanical action to more perfectly inject the precise quantity of fuel required at the precise time it is required. This serves to more completely burn the fuel and to eliminate the unburned hydrocarbons so problematic with older poorly maintained systems. The byproduct of these improved systems is vastly improved fuel economy and improved longevity of engine upper deck components. I continue to advocate recycling used diesel engine lube oil as fuel. YMMV. Butch "Bill McKee" wrote in message nk.net... But weren't these mostly mechanical fuel injection? "Butch Davis" wrote in message ink.net... Lots of opinions with little in the way of facts.

Butch, how do you filter it before adding it to the fuel?

John,
In the fleet application I used Racor's system which included filtration. On my personal diesel vehicles I simply added the oil directly from the crankcase to a nearly full fuel tank. My reasoning was that the lube oil was well filtered by the oil filter and that the after market Racor filter I always installed in my vehicles' fuel lines would do a good enough job of removing anything harmful. The Racor systems were not inexpensive but paid for themselves over time several times over. If I had a diesel boat I would have a Racor system or make up an installed one with a pump, some tubing and fittings, a valve or two, and a filter. Can you imagine an oil change on a boat with no mess, no oil disposal issues, and improvment to your fuel economy. The only issue would be the filter change. You could do it just like the pros.

In article ,
"johnhh" wrote: Butch, how do you filter it before adding it to the fuel? John The correct way is to run the used BaseOil thru a Centrifuge first, then thru a 2 micron filter. We have this system in our 2.5 Megawatt Powerhouse, and burn the resulting lubeoil in a Waste Oil Burner/Heater in the Port Engineers shop. The residue that comes out of the centrifuge is Classed as Hazardous Material, and we ship it to a recycler. Bruce in alaska -- add a 2 before @ |

All diesel inject is not mechanical. The new engines, like my Duramax or
Eisbocks Ford 6.0 are electronic FI. There is a high pressure, precision pump that generates the high fuel pressure to a single fuel block, the single rail. The Electronics pull the solenoid and allow a precise amount of fuel to inject. My duramax does 3 shots per power stroke. The old Detroit Diesels, etc had a mechanical piston to inject the fuel. You adjusted the "Racks" to get the best fuel burn on average. Was to early at idle, why lots of rattle (pinging) at low RPM's. Probably bigger jets in the injector also. Only one shot per power stroke. The new pumps will be close tolerance and smaller holes in the injectors. You would have to save a lot of money on diesel to pay for the repair of either the pump or the injector. Lots more for the pump. "Butch Davis" wrote in message ink.net...

Bill,
I understand. IMO, the system you're talking about is a system I first saw used on CAT diesels. I attended a CAT school in Peoria on the system and am familiar with it in an earlier generation. By my definition the system is hydromechanical with electronic control. The digital system decides when and for how long to actuate the solenoid which permits the already pressurized fuel to flow through the injector to be atomized and burned. BTW, virtually all high pressure diesel pumps are precision pumps. Detroits and EMDs were the only engines in my experience that used the rack control and unit injector system. Cummins used the PT system and CAT used an injector pump operated by a cam which pressurized the fuel in a timed fashion until the pressure required to cause the injector to "pop off" was reached. Roosamaster (Stanadyne (sp?)) used a distributor type rotary pump with injectors similar to the CAT pop off injectors. YMMV.
