Tried WMO heres results

This is all 6 injectors out of my 91 cummins motor. These were rebuilt about 6 months ago. For experementing I tried to run 50/50 diesel and waste motor oil. heated and filtered to 5 micron. On a 700 mile pull the truck got so weak it would slow down to 50 MPH on small hills. 1st Changed filters still no power, 2nd removed pump took it to tallulah injection 45 minutes on test stand no problems. Reinstalled pump and pulled injectors 3 were stuck open. on a pop tester thet wouldnt even chatter they just let diesel flow through.

How far was it filtered down? That looks pretty rough, how many miles did you run it? were you running it straight or cut with diesel?

Question

Man, that is weird. I've never heard of that happening, especially after only 700 miles! I've known guys who've run WMO for tens of thousands of miles in their 12 valve Cummins with nary a hiccup. Then again, I'm not sure at what ratio they ran it, maybe it was thinner mixture than yours? I am waiting for somebody "more in the know" to weigh in here with an opinion or two.

Is this your first time using WMO at this ratio? Did you use any synthetic oil? This was a perfectly running vehicle before you added the WMO?

Are you going to give up on WMO all together or just the high ratio's? I would call 50% a high ratio. I have been burning WMO for lots of years at 5% or less, including gear oil and synthetics, and still feel it's profitable. I'm surprised more WMO burners haven't chimed in.

with the injectors stuck open like that would you think over time your cylinder walls might get washed down, or any other possible scenarios?

This should be a alternative fuels sticky, can you give us an idea of your total costs to get your truck fixed and back to running normal. As well as down time. Were you able to limp back home to fix it,or did it have to be fixed on the road trip.

Truck drove back home on its own. One day of removing Injection pump. drive 40 miles to run on test stand at Tallulah Injection for 45 minutes. No problems with pump That cost me JB80 (being a chemical rep has advantages) Leave Tallulah drive 80 miles to wrecking yard to pull 6 used injectors for $10 each out of 95 cummins truck. drive back home 30 miles. tear all 12 injectors down to swap injector bodies. mine have 12mm threads for the fuel lines and the injectors I bought have 14mm so I just used the tips on my old bodies. To sum it up this cost me $60 in cash 5 cans of JB80 1 lost day of work. All the fuel I burned was in a customers Powerstroke. I had just built the rearend for. He told me to drive it and make sure he wouldnt have any problems so I did.
