WMO fuel, any long term damage or issues with soot buildup in cylinders?

[norbilla]

I am very interested in using a 50/50 to 60/40 diesel/WMO mix in my M109A3. Was told by someone who says they understand engines and that WMO will cause damage to cylinders/pistons due to soot/carbon build up. I don't think they have much experience with multifuel motors, and I don't know enough to really argue with them. Any good advice?

You will find many guys on here who run straight filterd WMO with no problems.
I think as long as you cut it with Gasoline or Diesel every few tankfulls to keep things clean you should be good.

Same as General Mcgregor just said. I once every 5 or 6 tanks run a 60% diesel mix to help keep things clean and its been running for years like this.

Been running WMO as a primary fuel for the least year and a half. From September to April, I mix it 50/50 with either gas or diesel(what ever is cheaper at the pump). Rest of the year its more of a 90-100% WMO to gas/diesel. Yet to see any side effects.

I hate to do it, I'll probably get my arse chewed but here it goes.

Does anyone know where I can get a 2 Micron spin on oil filter for my WMO filtering system.
Right now I have a 10 micron filter but before I use the oil for fuel I want to run it through a 2 micron filter.
please give part number and where you got it.
Thanks

I don't mean to High jack your thread either.

Thanks to everyone for the information. donttreadonmebmg, no worries, look at it more as more in depth information to the original question.
What about synthetic WMO? Will it cause any problems?

I ran a tank of $26/quart Syn race oil. The deuce loved it. I nabbed a 55gallon drum of it because someone dumped less then 4 quarts of WMO in it on accident. They thought it was the WMO drum.

4000 miles in one year on mine running 90% most of the time,still going strong.

Nice!


I picked up another 20 gallons of waste oil from a friend of a friend on my way home from work. I have been filling my tank up with wmo for 2 months now. I figured with the diesel and gasoline that is already in the tank will be a good enough mix for me to run 100% wmo now that it is warming up again. I thought I would stick in some diesel once in a while over the summer 10 gallons here or there, but for the most part, I plan to run 100% wmo.

At 3.85 a gallon for diesel, I will try to drive my pickup only when I am getting paid to do so for my job, otherwise on personal time, drive my deuce.

I've been running 90% WMO (filtered to 5 microns) and 10% gas per tankful for the last few months (1000 miles), I drive my truck to work and back almost everyday and have had no issues.

i havnt run any in mine yet, but my uncle has run a 80/20 mix for the last 7 years as a almost daily driver. he does run every fifth tank or so straight diesel with two quarts of atf in it. he only adds the atf because a old army mechanic friend of his told him it helps. no problems so far

one of the points I've seen Doghead raise on WMO being used, and the effects thereof: Waste motor oil is not listed as an acceptable alternative fuel.

Also, the multifuel engine was designed with a bit different purpose than a toyota sedan engine, they're not going to go 400k miles with minimal maintenance. I've seen new guys advised to stock up on as many spare parts as possible; that advice has to have good reason behind it.

That being said, I run WMO, and pay taxes on the amount that I use. The only issues that I could possibly, recklessly blame on WMO for engine component breakdown would maybe be an o-ring on my manifold heater, the O-ring was made out of Buna-N, which is described as having less-than-desirable tolerances to alternative fuels (such as brake fluid, gasoline, etc). The failure of the o-ring on the end of the injector caused oil to jettison onto the top of the turbo. O-ring replaced by Kelrez type O-ring. Now my heater has an O-ring that wasn't made by the lowest bidder.
