First of this is my first post on here and I am relatively new to forums, but here is my problem and hopefully someone with much more experience than me will have a solution.

I drive a 2002 Dodge 5.9 4X4, 6 speed, stock other than a K&N air filter. Recently I had been reading about using WMO in a vehicle so I bought the pump, filters and several barrels and began to filter the oil down to 2 microns. I did mix it prior to running it through the filters and it was mixed at a 60% WMO and 40% D2. When I filled my tank up with this mixture I had about 1/2 a tank of fresh diesel. The truck ran fine for several days, and then began to smoke white smoke at idle, and extremely heavy grayish smoke even under the slightest throttle/load. My immediate response was to add more D2 in an attempt to dilute it, and it had a minimal effect even when I added 17 gallons of D2. Since this time I have 1/2 a tank and I am trying to run it all the way out and fill up with fresh D2 to make sure nothing is permanently wrong because this is scarying me. The truck can be driven w/o really bad smoke, but you have to be extremely gently and have a feather foot.....to me this is not normal. I hear people on this forum saying they are running 90% WMO and it blows my mind, does everyone's trucks smoke this badly? I have also noticed quite a loss of power, the same hills I use to take in 5th or 6th gear I am dropping to 4th. I did just change the fuel filter for a safe measure and noticed the old one seemed pretty clean, and did not notice any difference with a new fuel filter. Someone please shed some insight on this. Thankyou.

Are you sure it is only motor oil and not mixed with trans fluid as well? lots of garages use the same tank to drop ALL their fluids in...oil, trans, gear oil, anti freeze, water etc........

White smoke can be injectors and things like trans fluid and anti freeze and water can be hard on them. I would not use waste oil unless I knew precisely what it was.

You may have a point, I do know there was some hydro oil in the waste oil I got, but there is a possibility it had some other unknown chemicals in it as well. So if you are burning pure WMO does the truck smoke as bad as I've described?

I would say run it with more D2 until you get her running like stock. Then start with a 30/70 WMO/D2 & work up till you start getting black smoke & a slight loss of power. Then back off a little bit.

You're going to realize that when it's colder out that you can't run as high WMO as you do durning the hot summer.

Also if there was synthenic in the WMO you'll be running lower percentages as well. I know that when I use Kerosene instead of D2 (use 1/2 the amount of Kerosene than D2), that I was able to run synthenic better and at higher ratios. Also putting some PowerService in your blend helps running the higher concentrations of WMO (> 30%). But this is all in a HPCR. Your GenII may handle a little higher concentrations.
