i just started running wmo today was the first long drive with it,
more black smoke and some blueish at start up when cold,
i did a 70/30 mix 70 gallons of diesel and 30 gallons of wmo.
that is the blackest fuel i have ever seen.

thanks for the great info!
so you've ran 100% waste oil with no problems. I may try 50% waste oil...
buying a spare set of injectors just in case..

I know for a fact you can run straight motor oil in a 1st gen because I've done it. Over the years I've run quite a bit of waste oil and very old heating oil in my various diesels and I've never had a problem. Cummins, Perkins, Isuzu and Mercedes have all run just fine. I've also never been careful as to the percentage. Just run what you want and all is well. Mine has all been on mechanical injection systems and not on common rail systems.
One night I ran my 1st gen out of fuel way out in the country. I coaxed it along as far as I could and finally it quit and was completely out of fuel. I poured in a couple gallons or so of motor oil that I had with me, bled the system and started it up. Well, it ran just the same as always and I drove on for miles.
To all the naysayers out there I simply ask you to show any damage that can be traced to running oil. I've asked this before and never got a response. No need for any guessing or theorizing, just tell us what failed because of running oil. If anyone can show damage it would be a great service to the members here and save them a lot of trouble. Meanwhile, I think it's a great way to dispose of and get some benefit from used oil.

what's your procedure for acquiring WMO, filters used, % of WMO used, etc?
any difference winter vs summer usage?

How about something other than motor oil. I have a large supply of used gear oil. I know it is a but heavier, and may have to be cut with more diesel. What do you guys think. I am running a 3rd genner, and have been using b100 for about 100k miles.
Thanks,

I'd be very careful about running that in a CR. 2micron filtration would be a must as well as a low mix ratio. Zero water is a must.

just poured in 3 gal of hydraulic oils from my buddy who services hydraulic lifts.
consistently have been running 85%+ waste oils
I'd really carefully running too heavy of oils like rear end lube. I'd thin it down heavily before using. our cummins will burn just about any oil, so long it's the correct consistency/purity to get thru fuel inj.

Ive got a 99 and Ive been running 50-75% WMO filtered down to 2 mic So far Ive had no trouble, I notice if I get much past 75% my MPG starts to go down so I am trying to find the breakpoint to not lose MPG's, also I dyno'd at IRP this weekend with 60% WMO i laid down 405Hp

i heard a bad story last week
a guy was on his way to lowes and a idot car pulled out behind him got right up on his tailgate then pulled him over and asked him what he was running diesel and the guy said no well the cop said he could smell his exhaust and that he could write him a $3000 \dollar ticket for fuel tax fraud the cop was nice and gave a warning told they guy to drain his tank and put diesel back in it makes me want an aux fuel tank for wmo,wvo

The cop will never write a ticket by his nose, and if he does and the person that got the ticket pays it they deserve it. Waste oil smells just like pump fuel. The worst case senario they will hold you up, call DMV, have officer come and dip tank, then write the ticket. Once again even if they do this they have to prove what was in the tank and give you a sample to have analyzed by your independent lab.
