can you drain the oil from your truck into a clean container and just dump it right in your tank? or do u have to filter it through something, and if you do can you go through like a coffee filter?

 

you can if you want. but you'll be changing your fuel filter often.

 

Sure. If you change your fuel filter every other oil change you will probably never have it plug up.

I work my WMO off in the ol' Benz. The fuel pump is darn near bulletproof, and the IDI design doesn't seem to run any different even with nearly half a tank of WMO.

 

There is no straight answer .
To start , what filters are you using ?
Some ex streams to make a point , if you were using a cheap oil filter maybe 20+ micron , and a cheap fuel filter 15+ micron .
What you are filtering out is particles / mostly carbon = abrasives .
Imagine that you are going to sand some old barn wood , to make something out of , you do not want to start with 600 grit paper , it would take you forever to get it sanded , you would start with 30 or 80 grit , so you would not have to sand so long .
Now reverse that , how long do you want your pump to last ?
Use the fine git so it lasts longer .
I have 2 oil bypass filter systems , one new Amsoil , on the truck , an old one for cleaning what I use for fuel .
A main oil filter , around 10-15 micron , then through the bypass [ 2 micron ] , then after draining oil , run through my older bypass [ that has the old filters from the last change , then that is pumped into a centrifuge [ 1/10th micron ] .
You can do what ever you want , but also do you want to have your fuel system last a long time ?
I notice that the engine runs a little quieter & smother with wmo [ average 30% ] , but bio-diesel is even more quite & smother .
I also only collect wmo for other diesels , no gas engine wmo - because of more acid like .

 

I used to filter it first, but now I take the oil drain pan out from underneath my truck and pour it straight into the truck's tank. Never clogged a fuel filter, and I don't change it that often either.

 

For the last 5-6 years I've run WMO in various ratio's as high as 90% WMO/Dino but I've always filtered my oil prior to pumping it into my truck through a 2 micron filter. I do believe that if you are only talking about 2 1/2 gallons fresh out of the engine into a nearly full tank of Dino that you should be fine since the oil filter is also filtering if the pan you drain into is clean & it goes right into the tank so as not to catch dirt sitting in the shop.

 

I have recently checked my fuel pressure [ about 22lbs ] , that fuel pump was new about 20,000 miles ago .
So it is possible that , the WMO has warn away the seals in the LP .

 

John if all the WMO you use is prefiltered down to 2 microns then I would think it might be the acids in the WMO. I don't personally worry about the wear issue as the savings will more than offset the increased wear due to the use of WMO.

 

man, that just doesnt sound right. How would a seal resistant to diesel fuel succumb to motor oil? If waste motor oil was THAT acidic, it would be eating our engines up from the inside out. I am thinking that there has got to be something else coming into play here. Like, maybe the pump having to work harder to pump a more viscous fuel than straight diesel. Just a thought

 

we got a 50 gallon tank.we run 50/50 .of motor oil and diesel.but we filter it first in to portable diesel tank.then it get pumped in to tractors and diesel heaters.and so far its pretty good
