Diesel Heater testing filtered waste oil - undiluted - part 1 

I chuckle when you apologize for the rain. The rain is good, it’s a little added ASMR

I filtered it and mixed it 50/50 and within 10days of 10 hours work it started to backfire through the intake chamber and flamed out it self and wouldnt restart. Took it apart and it was full of ash. I reckon its the antiware additive within the oil that form the heavy ash. The positive side for running oil is the immense amount of heat comparing to diesel that the heater generate it.

I tried this last winter with my shed heater , I tried lots of different ratios and always the same result flame out and build up of ash in burn chamber. This year my shed heater has run flawlessly on heating oil so far this winter.

Thank you for sharing your awesome diesel heater video. U run mine on straight diesel. I have seen them run on a 25% MOGAS with good results. Everyone stay safe, warm, happy and healthy. From Henrico County Virginia

A very interesting experiment. Looking forward to seeing the next ones. Happy Christmas !

I am really glad you made these videos, and I can't wait to find out what happens next!

Thanks David, great series of videos. I was pondering getting one of these heaters to burn off my waste engine oil and heat the shop a bit. You've saved me a bunch of trouble, thank you sir. I'll just continue heating with propane amd taking my waste oil to the recycling depot. Far less hassle.

sooooooo excited you are now doing this

Have a great Christmas Dave

Love these sorts of videos!

Last winter I ran my CDH with the Afterburner for weeks on hydraulic oil, the "32" hydraulic oil, worked great, I used a 50/50 mix with DPF cleaner additive added.

heres an idea with it being used oil and obviously with that less burn factor than fresh oil or diesel etc might be an idea to coil the fuel supply line (copper) round the exhaust whether that be 5-10-20 cold round the exhaust and of course ideally start and stop the heater on diesel/kerosene. bet that would make ALL the difference

Would be interesting to see same test done on brand new engine oil to see how much they clogg up inside if any. Have a good christmas an new year, all your vids are great an very informative

Nice burner you build 💪you can use a t paece and a extra ball valve to control the amount of air that is going thru the burner

ive run hundreds of litres through my 12v diesel, 50-70% waste oil cut with diesel, smoked more but ran fine well worth the savings at the time diesel was near 2$ a litre

Love the heater videos ! Also 15:20... That looks very familiar. I spent 4 months last year burning waste motor oil and has this same result, sometimes multiple times each day, haha. It's great entertainment if you really like experimenting and trying out viewer suggestions.... but you will get a lot of people (who have never done it) claiming that you are an idiot because you didn't _______ and then you try that thing and oddly they have no follow up response 🤣

4:20 "ill give it a wee nip" proceeds to hoof on it till the plastic strains 🤣🤣

Looking forward to this

That‘s exactly what I also had with my heater. I discovered it took longer to flame out if run on higher heat (which probably burns it off better). How about adding some DPF cleaner additive- which is supposed to lower the ignition temperature of diesel…and oil perhaps too? And next one with pure waste vegoil?

Good video - I look forward to seeing the results of the next videos! I've tended to conclude that the cost of white or red diesel is worth it for the reliablity & lack of hassle. However, I'm open to being convinced otherwise! Hope Santa brings you something cool, fun or embarrasing!

Yep, you can't run ANY motor oil in a heater, new or used, quick way to block it up unless it's designed to burn motor oil. Dilluted with diesel it will still leave deposits, it just takes longer.

My forced air garage furnace runs 50/25/25 of waste oil / petrol / diesel. 2:1 seems to be the right viscosity but anything over 25% petrol changed the combustion properties too much. I went with a smaller nozzle because it pumps out way more heat on the blend

Helloooo Cuzin across the pond lol have a Merry Christmas !

great videos love what you do , saw your key ring with 2 big skeleton keys what do they go to they look big , and queston you might be able to help wonder if its possible to put 2 same controllers on the same mob but one like 75 feet away in my shed using like cat 5 wire ?

Great video and I have learned a lot from your other ones. One thing i noticed was that when you were filming it the next day and you said that it had flamed out, it appeared that there was air in you pump suction tube. Had some drained back into the tank or had you lifted the pipe out of the tank for some reason?

@David McLuckie , what about burning new motor oil, as a test, to check how much tar and ash there is as a baseline. If it gunks up the chamber with new oil, then no matter how much you filter used oil, the results will be the same or worse. Thanks for testing and sharing the results with us.

What about other exotic fuels? I was at an auction recently and saw an entire pallet of i think it was either tiki torch oil or lamp oil. Was easily a couple hundred gallons of what is probably kerosene for like a dollar or less per gallon.

Try 4 pints oil, to 1 pint diesel, also see if 4 pint oil, 1 pint gasoline (or paint thinner) if it will burn or burn too hot... The soot buildup is due to the burn chamber not turning red hot (or staying red hot) burning off the crap buildup. I guess it just needs VERY VERY refined oil to make it burn properly w/o the buildup I guess the pipe dream of seeing waste oil being able to be burnt in that thing is a pipe dream...we shall see Keep em coming!!!!

My prediction is there will be no way to burn straight waste oil in a SUSTAINED fashion, say 100 hours , ( likely a LOT less) in these burners. I don't even thing additives are going to work. The reason is exactly what was shown here. The lighter fractions will burn off first and leave the carbon/ clinker. The burn chamber has to be up around 600C to get that to fully burn and turn to ash as could be seen at the end. I also don't believe there is sufficent air flow and turbulance to blow the ash out and it will build up. Furthermore, because the housing only runs sub 200C, the incomplete combustion products will condense out onto the housing walls and that section will block up. Fundamentally, the combustion process in these heaters is incorrect for waste oils. With an additive, petrol, Diesel, etc, I believe there will be some extension of the total amount of waste oil burned, IE, will burn more before they clog but again, won't do sustained hours and the amount of oil which can be burned over a decent time frame, tens of hours, will be so minimal as to be not worth while. Having said that, I very much hope I am proven completely wrong as the ability to run these on waste oil ( hope you try Veg as well) would be game changer. I am sure hundreds of people can get all the waste oil they want and it would be fantastic to have a free fuel source. I just don't think it's viable in these heaters simply because the way they are designed and the properties of the fuel are incompatible. the only way I can see this working is to modify the fuel by cracking ( pyrolising) all the carbon forming elements out of it just like refined fuels are treated and why they will work in these burners. Please prove me wrong!

Hi David, when you come to trying cutting the oil with other fuels can you possibly try a sample of kerosene please as a lot of people seem to be burning kerosene to save on costs during the winter as its a fair bit cheaper than diesel? It is also said that Kero burns hotter than diesel and is slightly less efficient, Im wondering if mixing it with waste engine oil would increase the efficiency and also burn the waste oil at a hotter temperature possibly reducing the coking effect in the burn chamber? I add strawberry scented two stroke oil to the Kerosene as my neighbour can smell the kero on start up and doesnt like the smell and I dont have any coking issues with the small quantities I add to the fuel ie 50ml to 10 litres of kero, this also seems to silence the pump a little adding some lubrication. Merry Christmas.

not expecting great results, I have tried just about every mix, whilst it ran fine I am still trying to clean the exaust residue off my wall - I am sticking to red diesel

You should try a 5050 mix of filtered oil and diesel fuel. Or maybe a 6040 mix. I have been running filtered vegetable oil and a diesel mix in my diesel heaters. And I've never had a probably at a 60% diesel fuel to 40% waste oil or sometimes maybe 5050.

The second that people figure out how to run these heaters for very little to no money the goverment will instantly ban them

was running used filtered veg oil and kero 50/50 but burn chamber kept clogging, can you take a old chamber apart so we can see how its made? also thinking of cleaning with caustic soda or cooker cleaner as carb and brake cleaner dont seem to be good enough, great vids

What did you wrap the exhaust pipe with? Could you please leave a link for where to purchase the exhaust covering? Thanks, enjoyed your video.

Someone should make one with a burn chamber that pops off easily so you can scrape the ash out. Also redesign it a bit so it's less prone to clogging when illegally burning used oil.😂

Wonder if you can you try the ignite wifi controller. Id also like to ask what's the minimum pump speed hz in afterburner tuning settings?

Need to design a burn chamber that has non stick walls, so the Ash just gets ejected out the exhaust. Maybe like a chromed cylinder bore on aircraft engines, or a different grade of stainless that stays shiny at temperature.

Could you use waste cooking oil?

Has anybody ever said that you sound like Billy Connolly, thats a compliment by the way..

what is your proposed series of test? PS- you can remove much of the additives.... least expensive less dangerous is to introduce Acidic Acid to the oil to cause the additives to drop out. You can the add a base (if needed) to bring acidity down.

I think you might have seen the pump size setting when viewing the WiFi screen settings

It it possible to run 2 pumps? 1 in diesel and 1 in waste oil. And a 1 hour switch to run pump 1 OR 2. Run 1 hour free heat waste motor oil and switch to 1 hour of diesel heat. After 48 hour of running and the last hour of diesel , disassemble the heater and check inside.

Just get a smudge pot and use your old oil in that it's made for it

warm oil to reduce viscosity - easier more efficient filtering and easier to inject into heater. the problem is heating the oil - could create an accumulation chamber (between tank and heater) for heating oil before filter before oil is used. Could use 30 watt heating mat to wrap around accumulation chamber that holds 300 to 400 ml of oil and then filter prior to injection.

I'm curious whether the oil you are using for these experiments is conventional, full synthetic, or a blend. I'm assuming by the weight and vehicle it's probably full synthetic. A mechanic that I know here where I live heats his garage with a heater designed to burn used engine oil. However, his heater performs very poorly when he attempts to run synthetic oil through it. It needs to be mixed at a ratio 7:1 conventional to synthetic in order to burn properly.

Did not even make it through the night! Interesting!

There's a video of a guy claiming that he runs his heater on filtered waste oil cut with 30% E85. E85 is 15% petrol and 85% ethanol. Search RU-vid for this title; "Chinese Diesel Heater burning Black Diesel - Waste Motor Oil" Seems to work well after some thorough filtering.

i think there is also an opportunity to see what else can be done to treat waste oil before use. could look to add some kind of ceramic filter material (broken teraccota) to remove metals and other ionic salt particles. what are you using in the filter? could put 30 watt heating mat round the filter to keep oil moving freely.

Probably straining the oil with a centrifuge would be the best chance of a positive result. So all the heavier additives aren't in the oil any more.

Hello there. Would you like to run through my dated Eberspacher? Iy's hot water only .prob 1990s ish.

Use an old Ipad or Android tablet for monitoring. You can have both apps open on screen at the same time then.

I bashed my head on a brick wall for far too long trying everything people suggest to use old oil in a standard heater. I have a idea I haven't tried yet making a larger heater using part of a diesel heater running on diesel to feed very hot air to a larger burn chamber for the oil that is easier to clean

I'd be interested to know how those big waste-oil burners that mechanics have get around the gumming-up conundrum. I've seen them run on absolutely foul oil, and not make much smoke in the doing of it. I know that running an engine on old waste oil is contraindicated unless it's been through a centrifugal filter. However, an old boy I knew ran all his big trucks on the oil from his scrap yard. He centrifuged everything that came out of the vehicles that came in, and bunged it into his artics. He said it can gum things up if you let it run too cool, but that's not a problem if you use the accelerator like a switch, as it's intended.

Please can I ask what pump you used to pump the old oil?

used vegetable oil? maby some tests?

Does the afterburner allow for a second metering pump so you can start with fuel oil and then switch to waste oil once warmed up?

Safe & sound rock wool will solve your rain noise from the tin roof.

Can you tweak the glow plug to come on periodically and prevent a flameout? Can you tweak it to run on highest power periodically to burn off the deposits? That‘d be what happens in a DPF of a vehicle exhaust…

what about 50% petrol and 50% filtered oil would that help?

so many people say that you can run these on waste oil and you just cant, ive made a load of my own oil burners before and know how carboned up they become, there is no way to run these on pure engine oil

Helllooooo!!

I ordered the 2kw heater and received the larger body heater. I am told this is a tuned down 5kw heater. I actually wanted the smaller 2kw heater with the smaller body I was looking to use it in a minivan. I think the large body heater will cause me issues trying to run it on low. Thinking I should return it and get the heater with the small body. The van is only 35 sqft. I am curious about your opinions and the opinions of others here. Should I install the large body heater or would it be a lot smarter to use the actual smaller body 2kw heater???? Any help would be greatly appreciated...

use old automatic transmission flouid ?

A messy game😊

I would guess bringing fuelrate right down to lean out to cause hotter combustion and burn off the crap.

Centrifuge?

may be you can put 60% oil 30% diesel and 10% gasoline so you can get your heather to higher termperature

Hi David, I am enjoying your videos. I am getting a vevor 5kw tomorrow, is there a best/cheapest fuel? I’m considering kerosene.. Thanks

The only waste fluid I've heard being successful is transmission fluid because it doesn't have things in it to plug them up

All the lovely additives getting burned and belched out is really good for the lungs too I'm sure, especially if someone's chucked in some zinc-additives for older engines... :P

It's

This gets done to death - the answer is no. In order to run waste oil at any dilution level, you need to be able to influence the ignition process. I.E you need to use heat (a blowtorch) in order to get a diesel/kerosene heater to start up when being run on waste oil/diluted waste oil. The factory glow-plug won't be up to the job. With these types of heaters, there's no practical way to introduce heat to initiate combustion - you will be relying on the factory glow plug. It won't do the job. Period. It doesn't glow hard enough. You will end up having to clean out the combustion chamber manually & it will be a pita. Run it on diesel. Torpedo heaters run alright on diluted waste oil - use it in those. Mainly as you can use a blowtorch to initiate those.

Ive seen a guy that uses a £300 centrifugal filter to get the oil super filtery...then uses 10% petrol and alegedly hasnt cleaned machine in 2 years.

Heavy oil steam boilers use a electric pre heater before pumping into the burner.

Sadly, reusing waste oil is illegal - just saying!

Waste oil better stick to natural and not engine oil lol . I did the same with brandnew 10w40 mixed with diesel 3/4 and it burned great but after three days poof lotta white smoke and it left a white crusty residu in my burnchamber it was a bit like perlite and it totally clogged it up . Probb the aditives in the oil that dont burn off .

QUERIDO DAVID, PORQUE NO LO ALIMENTAS CON ACEITE USADO Y HIDROGENO.UNA CELULA DE FABRICACION DE HIDROGENO Y SE ALIMENTA POR LA TOMA DE AIRE ASPIRADO.GRACIAS POR TU TRABAJO.
