Howdy! New to the forum...
Just traded my 01 F250 PSD for a 04.5 CTD 2500 4X4!
I love the truck but miss the room!

I ran used waste oil in my PSD for about 30K miles at a 45% mix. No Loss of power or mileage. I mixed diesel and motor oil in a 55 gal drum and used a 12v pump to circulate it through a TP Bypass filter for a couple of hours and then through a regular fuel filter into my 60 Gal auxiliary fuel tank. I just started mixing different %'s until a got to 50% and noticed some smoke during acceleration (more than normal) and then backed off a notch.. Bam! 1/2 priced Fuel!
I just installed the tank in the Dodge and I am going to rig it up so that the stock fuel gauge will work when I switch over to the aux tank... Sweet Setup from Northern Tool >> But cost a bunch!

I love the Forum... Very informative and not as many poeple complaining about ther truck!! To Tell you the truth... That is the main Reason I Choose the Ram!

Cummins says 5%, and the old rule of thumb was 10% max. My 3208 will start banging at 20%. I would not think of going over 5%. It will give a bit more mileage with it in.

I get about 600 gallons of used oil a week, never heard of dumping it in the tank. Other than geting rid of waste oil what are the main advantages of this?

Now ya'll got me excited about this.... I have 15 gallons of oil in the garage now trying to figure out what to do with it

Oilguy

I originally got the idea from a dodge forum thread (not this one) where people were mixing 30 to 50% in their truck with some that have gone 80+K Miles and if I remember right there was one that had closer to 200K miles with no related problems. I will dig around to see if I can find it again but I was looking for WVO information... Also you can Googe "Black Diesel" and get some information. I have an endless supply of waste oil (Quick lube business) and got really excited when I found this!

How would this work in cold climates? Would we need to heat the tank to avoid clogging or does oil and diesel have similar characteristics in the winter?

I know 15W40 is thick when its cold. Wondering what issues I might encounter if I did this.

If you were to try running a high percentage in cold weather you would have problems. Oilguy doesn't have winter as such.

Scotty, if that truck still has a cat the extreme pressure additives in the oil will cause it to stop working. I feel like if it's gonna be on there you shouldn't ruin it.

Oilguy

Yup... No winter here... Hot and dam hot are the seasons here in Texas. However I try to only run lighter weigh oils and as little syn as possible.. Too many friction modifiers >> They don't burn very well... I also run the aux tank and leave the stock tank with pure diesel so if my blend causes smoke I just run it on the highway and then switch when I get in town to keep it from smoking at idle. Then after I run the tank down a bid... I top it back off with pure diesel to dilute it. This is probably not a project for eveyone... just those of you that can deal with everyone thinking you are crazy!...

WannaDiesel... I see that you have a water/meth setup on your rig... Do you like it??.. I am thinking of puting that on mine before I go back with the fuel/oil mixture.

Seems to be a confusion here between WO and WVO. I have been talking about drain oil from the engine.

rebal

I have been running drain oil in my 90 for as long as i have had it (bought new)
it now has over 300k with the same IP and Injectors ,and runs like a champ, but i think its time for new injectors cuz my MPG is way low

wannadiesel

Very much! 200 degree EGT drop, and you can see the power/torque gains in my sig.

Ok guys, Im kind of new to this. I drive an old gmc diesel but, next month im buying a used but new to me 98 to 03 dodge CTD. This is the first ive heard of this. so tell me if i have this right? You can actually add a percentage of used filterd diesel oil into the fuel and run the truck on this as long as the truck does not have a cat on it?

wannadiesel

Yep, that's it in a nutshell. Cummins says not more than 5%. The oil doesn't have to be out of a diesel, oil out of a gasser will do just fine.
