Has anyone tried used motor oil as a fule in the 7.3 engine?

 

Not a good idea, but read this anyway: https://www.ford-trucks.com/forums/4...motor-oil.html

 

While I don't run used oil in my 7.3, I do run a 25% mixture in my 6-71 Detroit.(the old 6-71 really doesn't like this new fuel) When I have clean hydraulic fluid, I will run as much as 50% mixture of it. I have run this engine for several years at these rates with no adverse affects.

I have a friend who is running an older Mecedes 4cylinder non turbo on 75% used oil and 25% gasoline. He has run this car for over 2 years like this, and has no problems with it. He does have a mixing system which filters down to 2 microns.

 

Coincidence that I just posted a similiar question here:
http://biodiesel.infopop.cc/eve/forums/a/tpc/f/9751014871/m/5101055591

In reading the above link from Fabmandelux, it seems that some have run UMO with next to no filtering. In my query on the other forum I am talking about processing it just as I do my WVO, which many call overkill in the steps I take. This would include a mistwash for acids, settling, heating to seperate water and filtering down to 1 micron nominal.

 

I have a friend they run 50/50 on the farm.

I think they only run 25/75 in the trucks if they do though.

If you are going to mix in motoroil, Filter it good. There are metal particles in the oil, injectors probablywont like them much.

I would Mix it slow. start out with a small mixture if your serious with it. only 10/90.
To much and they get a little cranky. Anotehr guy on here tried it though, he said that his ford took a dump. =*( poor truck.

 

Do you recall some keywords in the thread so I can find it? This is something I've been seriously considering as I'll be picking up an older diesel soon....maybe today

Thnx.

what kinda look is that?! haha

 

That's the look that I posted that I didn't see where his motor blew up but where it only clogged the filter then after posting my response here I realized I hadn't clicked to page 3....since I can't delete posts here just dropped it to an embarassed look.
