Mixing Used Engine Oil in the Fuel?

[RWWinslow]

Our B Series Cummins was originally designed to allow used engine oil to be burned with the fuel at a rate of 10%. Does anyone do this and if so what affects, if any, have you noticed? (Assume that the used oil is properly filtered prior to introduction into the fuel system. )

I know there are some boat guys that do this..... and have been doing it for years... ... but they don't have VE pumps.

I am not sure what the difference between the in-line and VE pump would be with respect to a 5% to 10% mixture of oil in the fuel. If anything it should add lubricity to the pump, etc? My orignal concerns were on issues with additional carbon buildup in the chamber and on the upper ring. Any other ideas?

Making absolutely certain the used oil is CLEAN would be the major issue - but then, if it isn't clean enough for the engine, is it clean enough for your fuel system pumps?



THEN, there's the issue of carbon buildup in the combustion chambers and on valve stems - all that to save... what?

Now there's a name I haven't seen in the first gen section for a while!



How you doing Gary? Hope all is well with you. For the newer guys, Gary was here until a few years back when he stepped up to the 3rd gen section with a new truck.

Shucks Stan - I get over here pretty often - as you pointed out, I've got roots here!



NO, no 3rd gennie for me - the '02 I *do* have has far too many electronics as it is, let alone what the 3rd generation guys will be suffering with!

Oil? Man, I wouldn't put that in my fuel if I was payed to. Just like guys telling me to run ATF to clean out my injectors... bah!!!



If you want to run something in your fuel, run amalgamated or stanadyne.



I don't know what oil would do, other than carbon up your engine.

Mixing used lube oil with fuel

Burning fuel that has been contaminated with

used engine oil will clog your fuel filter

if nothing else.

The sut in the used lube oil will stop the

filter up long before it's normal service

interval, causing your pump to starve for

fuel needed for the engine and for pump cooling.

There is absolutely nothing economical in

this practice, especially if it has transmission

fluid mixed in it or even worse, anti freeze.

Yup... . I'm all in with the rest of the guys on this one bud.....

Do NOT do it.

Ok, ATF, motor oil, and all those related products were not meant to be burned. They were designed for lubrication purposes, NOT burning.

Soot, carbon deposits, fouling of injectors, delivery valves, and all related parts is a big possibility.

Besides you can go with a very cost effective additive like stanadyne or Howes meaner power cleaner even.

The cardinal rule, in my opinion is this... our pumps a lubed and cooled SOLELY by fuel.

You want to improve lubricity, and cetane ratings along with detergent properties and other items along this line and most of the modern additives will do that for you.

I'm getting to the point I cant keep a straight face when people mention this. They are usually older guys who have owned diesels longer than I've been alive, which makes it all the funnier. I dont bother to explain the differences in internal clearances and the greater injection pressures possibel as a result. I just try to make a speedy exit before I explode into uncontrollable laughter. :-laf

Some of us have enough issues on #2 alone, why add stuff from the oil dump to the mess? I wouldnt even put it in the Ford 5000 we have, circa 1965.

Is that a 5000 comander or the low profile tridishonal 5000. In the 50's and60's the big cummins and detroits in goverment aplications wer built to burn multi fuel's. Ther have true Injectors (we have nozzles). One inj per cylender acuated by the cam shaft. They could even burn crued oil. But not our little Ve pump engines.

 

[amsoilman]

Cummins Inc. has an engine oiling system that "burns" some oil, and then "adds" the same amount of oil that was burned, thereby reducing oil changes. I might add, our 5. 9 L engine is not one of them!

However, on the engines that have this system, they also have an EXTREMELY FINE FILTER that will filter the oil BEFORE it is burned!

Philips5, it is a Ford 5000, row crop version I think. It's almost as tall as the JD4020 he had till a few years ago. Nothing low profile about it. Beyond that, I just know it is a 4 cyl, non-turbo diesel, 60 HP sound right? Maybe a hair lower. Good haying/ feed grinding tractor.

I forgot to add that part the comander is a 6 cyl english style engine with sideways style inj. They are also whitsh gray hood and grill. yours is a regular style 5000 but flat deck. Most wrer sold utility version(at least in my part of the world).
