Running Waste Veg Oil As Diesel 

I have a very similar setup. Haven't used it for a long time but with recent fuel prices I will be getting it up and running again. Only problem I've had running it for a long time was the tank pickup tubes and pre-filter(sock). Several trucks with quite different tank setups but same issue. However it took 3-4 years for the problem to show. Also adding a biocide is very important. Thats why you're going thru numerous filters on the truck.

Really nice system!!! I ran that in my waste oil furnace and it smelled like frying chicken. It made me hungry!! Thanks!!

Well that was interesting! Yep I think in the future the 353 will be on veg oil , early Detroit's were designed as multi fuel engines !

the main issue with veggie oil on common rails is polymerization of the veg oil when it gets squeezed to 30k PSI... makes a nice snotty mix that seems to resist everything but muriatic acid :)

Ran 1000s of gallons of home made biodiesel and 90/10 WVO/gasoline in my 1996 7.3. Biodiesel that truck ran clean oil was still amber colored after 1000 miles. 0 power or mileage issues with biodiesel. I would suggest running some of that after settling oil through that centrifuge and see what you pull out if it. I would settle the oil in totes for years sometimes before getting around to using it and draw off the top, I bet you will be surprised what you find in the centrifuge after running clear clean lookin out through it. I just settled pulled through a rough filter into my fuel barrel and pumped through filter into truck with the blended wvo / gas. never had any issues. but I never wanted to spend the $$$ on a centrifuge if I had found a good deal I would definitely have used one. if you use the centrifuge the slower the oil goes through the better.

Remember to turn the saturated fat fractions into biodiesel, mix that back into the unsaturated veggie oil fractions and use up to 20% pure gum turpentine or 30% gasoline with a cetane additive to mix into the final mix. It works pretty good, also be sure you filter it out we and preheat the fuel as it goes through the lines into the injectors before burning it.

The truck fleet I worked for would add 5 gallons of JP-4 ( jet propulsion ) fuel to their 20,000 gallon underground tank for its anti-gelling properties .

stainless steel reusable mesh filters for water filtration will work and save spending money on filters having a disposable filter at the end seems to be needed the trick is making it last as long as possible with reusable filters

If the veg oil gets hard to find you can always add a centrifuge inline and start processing waste motor oil. I’m working on a set up now and have just found a source for some high end waste oil even though it’s synthetic everyone says it should run fine with the correct rug mix. Hopefully I will be up and running this spring.

I used to burn WVO in my 1993 6.5. Thinned it 30% with kerosene, and added cetane boost. Other than installing a pre-spin-on filter on the frame, I used the factory fuel filter up top. However, it got cutthroat out there getting the oil so I stopped. I used whole house water filters on my holding tank then the last one being a Goldenrod water separator filter. It was fun while it lasted.

Yes, u can rig an onboard heat exchanger in your truck also that will help out, especially during cold. Instead of tapping your radiator lines, adapt your eng oil filter with a sandwich plate to an10 or pipe thread input/output. Run an insulated hydraulic hose to a liquid to liquid 60 plate chiller, maybe another in series, but parallel the hot loop. Send the eng oil back to the eng bay where u relocate your eng filter, finally route back to the sandwich plate. Add a pump inline somewhere to assist flow. Oh and I guess u might need to make a switchable valve bypass for the engine oil cooler during moments that you want to heat wvo.

Thanks for sharing.

That is badass

Just a suggestion a poly cone bottom tank is so much nicer for settling and draining off

"Black" diesel is the go.............centrifuge clean the sump oil, blend it with JetA1 or gasoline to get the right density, and then filter it at 2 micron. The market for used cooking oil and other " yellow grease" products is pretty hot, and nobody will give it away. However, sump oil is much cheaper and easier to get.

Good stuff, thanks for sharing.

Very interesting thanks for sharing

I was thinking about converting a 2003 sprinter van to veggie oil, Is their a fuel sensor and if so would I have any issue's with the fuel sensor? And if so how would I go about bypassing the fuel sensor? I also want to run straight 100% veggie oil, So if I use a 2 tank system would 100% veggie oil work If I start on diesel and flush before I turn the truck off or would I still have to add gas or diesel?

From the UK, apologies but such an interesting post got me thinking (too much again). Over here you have to pay duties/taxes on such products, is it the same in Canada? What's the difference in fuel consumption with straight diesel?

is salt content-chloride--high in the veg oil fuel?

Im just getting into this uco

i would run waste atf. I did this on my 82 300sd. just find a trans shop that will let you take the oil. You will have to filter it. It works better than any other fuel. you can filter it thru a 5 micron bag and it will be fine.

Here in Australia, can't get waste vegie oil. They keep it under lock and key.

Neat, ez system. Seems to run fine in mechanical high pressure fuel pumps. Anyone try it so far through CP3? Duramax especially. Thanks. Quite a hoot. ⛽ 🦉

Great job on the conversion. You covered all the bases. I remember seeing a home set up where you can make your own biodiesel from waste vegetable oil. Comes with the tank and all the stuff you need. The only caveat is that if you sell the biodiesel to others, then you have to pay fuel taxes. The high diesel prices is one reason why the company fleet is all gas. $3.89 is cheaper than $4.79 diesel. Looking forward to the next video.

can you use that sameway but useing used motor oil

Neat system you have going. It would be interesting to me to calculate cost per 100,000 miles driven on diesel assuming a filter lasts 25,000 miles versus cost per 100,000 miles on WVO changing the filters on the truck and treatment system as required. I’m sure there’s still a significant savings, but with filter costs added in my intuition says maybe more like 50% savings vs 80%. Curious your thoughts! As an aside, how many miles since the re-ring now and how many total on the silver?

wow i imagine i can use this in my 692 boat engine

Thanks. Are you using any waste motor oil?

I wanna see a oldsmobile 5.7/350 diesel engine run on waste vegetable oil.

I watched the video you linked about the settling system. I am wondering how you slow down the flow into the first tank when adding oil? Does the filter over the bucket slow it down sufficiently?

Do you use any additives?

👍

I want to see those results from black stone labs on your engine lubrication oil!

Does it run any different with higher octane gasoline? We use a lot of donaldson filters p558010(20microns) witch is a secondary water separator. And with a p551313 primary filter (2 microns)

so do you start your truck on diesel and switch to veg oil when its warmed up? if so do you use 2 different tanks ? thanks

Have you tried waste motor oil?

That so called biodiesel sux I drove for Walmart and there Arizona DC used biodiesel I quit fueling at that year because my horsepower went to crap and my fuel milage was crap on that garbage also,just like the flex fuel in my suburban I used the methanol once my fuel milage was about half and the horsepower was way less.

Thank you for the video very helpful

Could you mix waste oil and vegetable oil and diesel?
