Can confirm that this works. My dad had a Toyota Hilux, and he used to make biodiesel with used vegetable oil from restaurants and mixed a little ethanol and caustic soda in to balance out the PH and clear out the imperfections. The trick was to let it stand and precipitate for about a week it get a clean mixture and not clog up your filter in your engine. When he drove it smelled like you deep frying chips. Restaurants would just throw the oil away and he'd just collect it from them each week for free and save thousands on diesel costs each year. This was back in 2000s though. He eventually got tired of doing it, because it involves a lot of work physically carting and tipping 25 L buckets of oil, though he made it easier by converting two old 1500 L propane tanks and pool pump into a kinda diesel brewing station.

An old Diesel will run on anything that provides lubrication and is flammable. Ran my old Diesel for years on used hydraulic oil. As we had cranes and diggers there was always enough waste oil. I was happy I didn't have to pay for fuel and they didn't have to pay the waste fee. Only in winter is was hard to run it a 100%. Also the diesel filter tend to clog up nmore regularly. Adjusted injection time and amount slightly and it was all fine even without massive amounts of soot. Without that there was loads of soot. Did that from 2002 all the way to 2014. Sadly it was just all rotten then. The last 6 years only a talented welder kept the car alive but then even my colleague said, get rid of it, I am tired of welding it and there's nothing left I can weld anything to it. So of course I failed state inspection but just for the amusement to see the inspector in shock I went there. Best times

[@gunnarbrunstig8377]

Hydralic oil tend to smell awefull and raise The engine temp 5-10 celcius. Used Engine oil is better. NO smell and does not affect The temp that much, but on The downside you have to change filter more often.

[@no-damn-alias]

To begin with I had hydraulic oil to hand and not used motor oil. So even if I wanted to I couldn't. Moreover engine oil has a much higher viscosity than hydraulic oil, which makes it even harder to use as a fuel. Even the lightes 0w-16 is thicker than hydraulic oil and moreover most oils are a thicker grade. Further there's a lot of junk, soot and dirt in used engine oil which would strain the pump even more and most of those particles are finer than the filter so they will get into the pump. Have you ever burned used motor oil? It just smells horrible and it will smell the same out of the exhaust as hydraulic oil. I don't see any advantages and at least on my engine hydraulic oil would also start with one cylinder that had rather bad compression as one glow plug broke during change out and the tip fell into the cylinder. It kept running like that for four more years. Before it went to junk I took the head of and the cylinder wall was heavily scratched and there was massive amount of soot around the spray holes on the injectors. Took the head of before scrapping it.

The thing is how many old diesels are about now, in the uk. Most are common rail. Which can be a little funny with this sort of thing sadly. But i remember a few people doing this to the old Turbo diesel 306s, a few used to mix a little bit of diesel in, just to thin it.

[@themightydash1714]

Yep, people think it's a diesel engine, but it's not, diesel engines are just compression engines, they will run on literally anything that explodes under heat and pressure.

[@WillowLiv]

That you said is a little stupid considering every single car engine is a compression engine, be it diesel or gasoline. The fuel is always compressed, the difference being that diesel engines don't require any ignition to run and as such they skip a huge timing element. Which is the reason it can burn with so many different fuels. While in a gasoline engine its very easy for the mix to knock, that means it detonates prematurely. I believe you should be very careful about what you use to run your diesel engine. If its combustion speed is too slow it could keep burning all the way trough the exhaust. Another problem is it could leave soot and other particles behind. Wouldnt run it on anything thats not the specified fuel if I care about long term reliablity.

And now vegetable oil is worth the same as Diesel

[@ConnorNolanTech]

The real appeal of vegetable oil is being able to get it for free from restaurants who normally have to pay a disposal fee. Yes, it costs more or less the same as diesel if you go to the store, but it's more than possible to pay zero for it and only be out the time it takes you to strain it.

[@Professional_Youtube_Commenter]

@@ConnorNolanTech this is the other reason when running a car on veg oil is no longer all that beneficial. Big industries are buying up used veg oil from restaurants, there are commercial biodiesel operations that pay restaurants for their oil, some get rebate from their oil supplier such as makro, bookers. So its quite difficult to convince restaurants to give you their oil for free. You need to match bookers and give them 20p a litre. You also need to do regular collections, you can go i as and when you want to. You gotto go and collect regularly without fail.

[@Savagetechie]

Higher injector pressures prevented people running on straight veg oil but pretty much every pump in the UK is minimum 5% bio.

[@beemoh]

You don't get a lot of crops specifically grown for Biodiesel because there's a certain amount of (not unreasonable) hesitancy from farmers to spend their limited amount of land suited to growing food on growing engine fuel when there's so many parts of the world suffering from famine. There's also the problem where if you're using recycled cooking oil, like in this video, you don't really see a lot of cooking oil in one place- a one or two litre bottle of oil will last most families ages in the kitchen, certainly significantly longer than it'd last in an engine. It's really only the preserve of large fast food chains who run their own fleet of vehicles to be able to have enough to make it worthwhile, McDonald's UK being a good real-world example.

Did a project for chemistry on bio diesels I compared peanut oil, canola oil, corn oil, and vegetable oil. Based on how hot they made a container of water while burning using the same amount of each liquid, I determined the best bio diesel and I also compared the US prices per gallon of each liquid. Take a look at the excel data results of around 200 experiments. Average energy produced for vegetable oil was 16000 J/g. The second best was around 15900 J/g which was from canola oil. The average price per gallon of Vegetable oil was $6.90 per gallon and $6.80 per gallon of canola. Corn and peanut oil were a lot more expensive. All in all, if you do the math, vegetable oil burns the most energy per gram and can be bought for as cheap as $5.00 a gallon from Walmart and other places

With the first and second generation TDIs, having BOSCH distributor pumps VP37 and 44, it was really quite common in Germany to run on rape oil, the sort CHM tried to grow in one episode. It was better than the scalled bio diesel, cause this was not only estered and therefor saur (which ate your fuel pipes and seals up), but also hell a lot more expensive due to taxes. The gallon canister of rape/canola oil was 50p equivalent (1,50 DM). The rozzers couldn't do something if they smelled a rollin' chippie ahead, cause else as tanking coloured heating oil it simply was not no fiscal offence. Later the stuff became more expensive, but with one Pound a gallon driving was still quite cheap. The only problem was the danger of thining the lubrication oil when the motor was cold. But most Taxi drivers didn't have to give a shit and for me, who I had to travel 300 miles with and to my former employer, it was no problem to arrange the tanking around the trips, so that I could start and drive the engine warm with a neary empty tank of fossil diesel and then changed to veg-oil. And in Africa the children didn't know what to eat. Today it is even more cynical. While more and more people on the planet can't afford cereals anymore, we mix it with faeces and waste the stuff in biogas reactors. So if you have one of the old 1,9 oder 2,5 TDI with VP37 or 44 or older (with Bimmers and Mercs and all the others it works until they have Common Rail Injection (the pump needs to be lubricated by the fuel and veg-oil does simply not support the job)), feel free to run on chips oil!

[@Fetii]

It does work on Audi's with the 1.9 TDI engine with common rail injection?

[@MrDarg4]

Vegetable oil lubricates better then diesel. The problem is viscosity, but if vegetable oil is heated to 60-70 celcius its basically identical. When it's cold, the vegetable oil can easily clog up fuel lines. So the ideal scenario : diesel on start, warming up the engine and the fuel and switching to vegetable oil later.

My personal experience of these old Volvo 740s is they are superb. I had one that had passed 400,000 on the clock and still going. Very comfortable.. Nice size and steers great too. The AA or any breakdown service involved in pouring fuel no widely used into a vehicle would never be allowed on todays telly.

A few years ago I ran my diesel land rover on a 50/50 mix of veg oil and diesel, once you added the veg oil you just had to drive it around the block very jerkily and swerve about to mix them up, but as it got cold in winter you needed to switch back to neat diesel!

Top tip guys. When you fill-up from empty put a teacup full of two-stroke oil in and another teacup full of super unleaded petrol and your car will have a much more powerful engine will be quieter and if you go for a mot test the emissions will be better than new. Keep smiling boys.

[@HoseysUtube]

I heard 'put a drop of petrol in with the diesel' is good

[@radionutio81ij79]

50% to 50% summer and winter mix is best as it requires no tank and fuel filter heaters to use in winter temperature. As you increase veg oil from 50% mix the viscosity gets thicker, summer driving a 70% veg to 30% diesel is aok but reduce veg quantity as the weather gets colder. Been using 50/50 mix in my 2.8 4x4 since 2006 without problems.

[@MrVonKruger]

Wow, in all the months people have replied to that question, yours is a new one. Did you read this some place or could you provide a source? I've actually, over these months, become very educated on this subject, even to calling and talking with many Oil Companies.

[@ethanelliott1832]

“On the newspapers and radio” before modern social media. I wish it hasn’t changed

[@t60njw]

I would really love to try this in my diesel car but there is one thing that i'm worried about. As we all know that veg oil thickens when it gets cold and could cause a blockage in the pipes. Then that would mean hassle and money. So the money that I was trying to save in the first place would be used to clean the engine and depending on what car you have could be costly. I mean, the answer could be, just use Veg Oil in the summer.. I did hear that if you mix 50% diesel and 50% oil then it may not thicken. Still a bit nervous doing it though.. Anyone have any suggestions?? Or anyone that is actually doing this.. I just think it's such a GREAT idea..

[@PizzarooThePizza]

Late to the party but 50/50 is fine. Iif you're really worried it could be 70 diesel/30 WVO

[@TheSuperBoyProject]

You shouldn't do this in any modern engine, let alone in the UK. I live in the Mediterranean and I have a car from 2013 and I don't dare try anything other than standard diesel any time of the year because the repair bill will be more than any savings you end up making. You need to do an actual vegetable oil conversion to have something like this run and it is a lot of work. You need a second tank to start up the engine with regular diesel and heat up the oil in the regular fuel tank before feeding it to the engine, with separate fuel lines, filters and fuel feedbacks back to the tank.

As far as I understand, diesel was originally designed to run on vegetable oil. But the thing about diesel is theoretically, if it explodes with enough heat, and you can get it into the cylinders, you can run your car on it. That's why I love diesel, it's just a really good design (the engine lifespan is also a lot longer than a gasoline engine, since the diesel lubricates the engine).

[@jayswarrow1196]

Diesel lubricated only fuel pump parts (which are not present in petrol cars, therefore no need for fuel to lubricate anything). The crankshaft and cam gears are still oil lubricated. Diesel engines last longer simply because they're built for way way larger compression, and the expansion of the oil-based fuels is "softer" on the cylinders. But you're not far from right: Rudolph Diesel (the man, who invented the stuff) originally aimed to run it on the lamp oil, so he danced around high-compression detonation principles, thus, creating "flexfuel", way before that became a thing.

@Gray Jedi I think you need help mate, you seem to have a few screws loose

[@carlosandleon]

@Gray Jedi they give off more pollution because they have more people. But if you divide their emissions by the population you will find they operate 10x more efficiently than the western population having a per capita emission 10x less. So really replacing the western people with Indians and Chinese will reduce the emissions of the west lol

[@rhythmaster2350]

Banning deisel cars in Germany? I did Nazi that coming?

[@CarlG84mm]

Carlos Leon It’s not as black and white as you say it is. Per capita emissions in India and China are lower (not nearly 10x but still lower) mostly because people are much poorer on average in those countries than in western countries, and thus use less resources. So your suggestion here is really that if we all become much poorer global emissions will go down. Not sure about India but definitely if the average Chinese person lived like a westerner their emissions per capita would be significantly higher than any western country since China relies heavily on coal for power generation.

It's very popular in Poland among taxi drivers, but they are using fresh oil from discounts.
