I change mine yearly, I cut the last one open and there was no sign of any buildup on the surface of the media. I was looking for big trash or metal on the surface and didn't find it. Basic cleanliness seems to be enough to keep the big trash out.

 

This is getting interesting. Do you think 1qt. used oil per tankful provides as much lubrication as 1/3 qt. of a popular fuel treatment? Seems like an old time toilet paper filter would remove any abrasive contaminants and near about anything else.

 

Anyone doing this in 3rd gens?

 

I dump all 3 gallons in the tank at once then go filler up

 

I'm too afraid to run waste oil in mine, especially of the HPCR, but I do run a non=detergant 30wt oil.

 

i have run rotella,hydraulic fluid and cutting oil from my buddies machine shop. i dump 3 gallons in every chance i get. i burned 10 gallon of hydraulic fluild on a 1500 mile trip in 26 hrs. the miliage stayed about the same. i have never had a problem burning it.

 

Gunracer:
How do you filter, especially the cutting oil before putting it in the tank ?

 

Get a remote fuel filter at Tractor Supply and a 12v pump... Put the pump so that you are sucking through the filter ( this will make the pump last a lot longer with having to slean it out... then you just need to add hoses and away you go!
I have one set up with a filter on both sides just for CYA reasons

anybody had any trouble usin burnt oil in 2nd gen 24v being they seem to have a moody injector pump

and is there and online publications cummins have out there sayin it is ok?

I would love to be able to do this being I have such a good supply of used oil as long as I can keep the old vp44 happy

 

Read Infidels post here. This is an older thread on running used oil.

the used oil is good for the pump,valves and it burns clean.
to see just how clean it burns just look at wannadiesel avitar

 

Here at the plant we have gone away from it due to concerns about particle contamination. The filters on the 980G are 5 micron I'm told. The concern is scoring the insides of the injection pump. Thinking is that there is no problem on the 20 year old dozer but the new 980G and the 771's not a chance worth taking.

 

5 microns ... the filters take anything out that will hurt the pump...anything that gets past them should not hurt it cus it will be less then 5 microns

 

Rotella T synthetic is not a true synthetic or PAO base stock, it's just super refined dino oil. Just wanted to throw that in there for the ones comparing dino to synthetic oil for burning purposes and different effects one or the other might have.

 

I just started using my old oil as a fuel. Just using 1gal per fillup so far no problems. As far as Cummins saying use no more than 5%.... I CANNOT FIND THIS INFO ON THEIR WEBSITE. They talk about not using more than 5% bio-diesel, but never mention waste oil...at least from what I can find. Can someone show me the quote.....PLEASE
