Burning drain oil

[SEmerson]

What is the highest level of drain oil anyone has ran. I have ran over 50% myself. I just got a endless suppley and would love to go 100%.

Hello semerson,



there is a thread running on that very subject at https://www.turbodieselregister.com/forums/showthread.php?s=&threadid=105140



I also have been up to 50%

I consistently run WMO in both my trucks. The old '92 smokes pretty badly if you go richer than about 40 to 1. The 01. 5 makes no noticeable smoke even at 20 to 1. I have over 70,000 miles on the '01. 5 and have been adding oil since it was new... no problems noticed yet. The old '92 is at 325,000 miles... also without problems.



You can filter WMO better and faster if you add some diesel to it to thin it down. It makes it more of a pain to carry on long trips, but around home it doesn't matter much.



Also, I run a two quart spin on filter under the chassis on both trucks as a pre filter. I run my filters until the fuel pressure starts to drop... that is often over 30,000 miles. I must not be getting too much dirt in with the WMO!

"I must not be getting too much dirt in with the WMO!"



Sorta depends on the filtering ability of the specific filter you are using - some will pass some pretty big stuff...



The older injection pumps seemed more tolerant of contaminents - but I'd sure be cautious with a newer close-tolerance pump type like the VP-44...

good info re: adding diesel to the oil to thin it a little for filtering

Geez, the most I've ever put in was 1 gallon in a full 35 gallon tank.

I put the other 2 gals in the aux (60 gal) tank.

I've heard of this WMO-burning keimmo guy before



I finally got the nerve to try a little in my '03 but didn't put much in, maybe 2-3 quarts. I also added 5 gallons of veggie oil to the tank tonight.



I heard that if you run more than 20-30% you should cut it with a little gasoline, maybe 5-10% of the oil volume you add (not 5-10% of the tank volume). This will help thin it down to be closer to diesel in viscosity for better atomization without hurting lubricity to speak of. I wouldn't worry about adding gas unless the weather is cool.



I would NOT run WMO or WVO in cold weather or if you mostly run around town, save it for warm-->hot weather and road trips. And add some good fuel additive to keep things clean!



I ran many gallons through my '01, when I pulled the injectors at 50k they were clean as a whistle.

never cut with gas. Use diesel or keresen

You guys are just now facing what I have faced for years... high fuel prices. I am American born and raised but have lived in central Mexico for almost 17 years. We have paid around $2. 00 per gallon for diesel for years! Kind of makes you think of cheaper ways to do things!



I talked the the filter manufactor before installing my pre-filter. I am running what I am running based on their suggestions. The pre-filter is about 1 micron bigger than the factory filter. When the fuel pressure starts to drop, I change BOTH filters.



I do not worry about cold temperatures down here. But, when I go north in cold weather, I cut back on the percentage of WMO I use... don't want a gelling problem.



Cost of filtration is a concern. I built a manifold with 4 filters on it. Do not run the filters in series... running the oil through one then another. Run them so the oil can go through any one that will flow and flows through only one filter. Used filters that are partly plugged will filter out finer particles than a new filter... and used filters are free. I have filter bases for a variety of filters. As the flow gets slow, I change a filter or two. This system is virtually free! It is not fast since I gravity feed the oil, but it filters oil faster than I can use it!



Heat will also thin the oil and make it flow better.

This thread has some interesting discussion but when someone mention pouring Gasoline in Diesel I had to reply in case someone new to Diesels is reading this.



Octane and Cetane are opposites. If you add Gasoline to Diesel fuel it lowers the Cetane in the Diesel fuel. (lowers power)



Gasoline is considered a solvent.

Diesel fuel is considered to be a lubricate.



The main problem is Gasoline lowers the lubrication qualities of Diesel fuel which is not what the injectors and injection pump need. If it doesn't gall and seize it will aleast accelerate wear on injectors and injection pumps.



If cold weather gelling is a problem there are plenty of good addvitives out there that won't do the damage gasoline will.

NEVER put gas into diesel!!!!

Ditto's, Kent!!!



Never, never, never mix gas into diesel. The flash point is lower when mixed than either of the two separately, the lubrication is gone, (we have a hard enough time lubricating fuel pumps and injectors now with the low sulfur diesel) and since there is less BTU content per pound, you will lose power and economy. It's not worth it! Use the correct tool for the job!
