I would never buy a french car.
The Delphi equipped smaller versions, yes, just as they do in Fords, Hyundais, Renaults and various others too. The larger PSA HDI stuff is Bosch or Siemens and nothing like as bad. Picasso will probably be Bosch.

Well its been a while since i have been back on, but i can report my car is STILL going strong!

I have tried all sorts since then and the Mitsuibishi 1.5 turbo Cdi laps the stuff up smile, dont get me wrong i wouldnt put straight heating oil in as that WOULD cause problems as its a dry oil, but as long as you mix it its a no brainer.

Ignore all the internet rubbish about it breaking your car, proof is in the testing and i have done just that :P

All you have to do is just mix it and not run it straight, be it using vegetable oil as the lubricant or just simply normal derv.

Yes, but what have you gained, if anything?

I came across this thread when researching using diesel engines in aircraft, and how a modern lump performs on JET-A1 (which is essentially Kerosene, or straight Heating Oil... but the JET-A1 has additives to prevent it from freezing at high altitude). Note, if anybody else is using heating oil which isn't kerosene you need to pipe up, but as I understand it all heating oil is kerosene.

Anyway, it's interesting that the most successful user here is using the diesel engine out of the Smart car. Because that engine has been used in airplane engine conversions: http://flyeco.net

I'm not sure what (if any) modifications they do for the engine to run on JET-A1 instead of forecourt diesel. The engine is expected to have a 1500 TBO, which is basically 1500hrs at very high revs before it needs an overhaul. No prices, but they probably charge in excess of £10k, it's uncommon for anybody to charge much less than that (the Rotax 912 petrol engine sells for the best part of £17k, and that started life as a snowmobile unit!). Clearly I'm in the wrong industry... wink

There's also the Diamond aircraft that now use converted Mercedes diesel engines... at £60k per engine! Though I suspect there's more modifications gone into those as it's a certified unit... but still somewhat crazy.

I've not used heating oil, but I have used pure veg oil in an Escort van which I use for business.

My post is re the duty payable. HMRC allow you to use 2500 litres duty free per tax year. If you use 2501 litres, you need to pay duty on ALL the 2501 litres. Duty rate is around 56p per litre.

Section 2.4 tells you your obligations...

HMRC page

I asked HMRC, and it is the amount that you USE per tax year, not the amount that you BUY. This means, you can buy 10,000 litres in one go if you want.

Hi folks, first time posting on the forum. The 35 second diesel is used for diesel engines because it has better lubricating properties, ie it is a heavier oil. 28 second diesel is too light (inadequate viscosity) and using it as fuel for your vehicle will result in damage to the internal moving parts of the engine in the long-term. This is much the same as a two stroke petrol engine in that the engine needs lubrication in the fuel though in the case of a two stroke engine it is because there is no reservoir for engine oil.

Also the difference between petrol and diesel engines should be noted. Petrol engines have sparks plugs which create a spark which ignites the petrol. Diesel engines have glow plugs which heat the diesel. A diesel engine works on the principle of suck, squeeze, bang, blow. As the piston falls it sucks diesel into the combustion chamber and compresses it on the upstroke until it explodes, driving the piston back down and sucking more diesel in to repeat the process. Diesel doesn't ignite or burn as quickly as petrol but is more explosive when compressed.

Red diesel is agricultural grade 35 second diesel and is not usually allowed within city limits because is dirtier than white diesel and pollutes more. The give-away sign is the dirty black exhaust fumes.

In short stick to 35 second diesel for your vehicle.

In a complete aside I wonder how much 28 second heating oil a petrol engine can cope with by percentage. I have unlimited amounts of that at 60p per litre compared to nearly 140p for petrol so if I could add 10% to the petrol in the tank without the engine blowing up it would save a few quid.

Heating oil or diesel will end up in the sump, diluting the oil with obvious consequences

Wont be any different to putting contaminated petrol into the tank and running it.
As did this years ago after draining a friends tank who put some diesel into their petrol tank.
We drained it and just used the fuel in an old junker MK5 Escort
After a few days the oil light started flickering at idle. Oil level in sump had risen dramatically, and it was very very thin

At a garage the other day chap comes in with a LR, reckons he runs it 50/50 diesel/chip fat (picked up from local Chinese) in summer but drops it a bit in winter as the LR won't start because the oil becomes too viscous in the cold.

I can't go 50/50. I go for 10% veg oil during the summer. I have run a twin-tank system. 22-litre auxilliary diesel tank and the main tank was for the vegetable oil. That ran on 100% veg oil after the engine had been warmed up using diesel.

I'm New here . But old wrench. I can say happily running heating fuel regardless of weight in my audi Rs3 and passat she clicked 250k before sub frame became Swiss cheese.
I put a few galloins in from the pump once a month but if your using modern heating oil it's fine. A shot of 2 stroke in a tank but at .40 a ltr delivered no waiting in the line for me!🤔

Strueth. Thread resurrection or what.

Sadly I’m not quite sure what you are saying. Can you reword it for us imbeciles.

An old diesel would probably run you know one from the 80's with no turbo and basic injection. A modern diesel however runs to high a comression ratio and the high pressure injection system will die with the wrong fuel.

Add to that the ecu won't be able to fuel it properly due to the different energy content of the fuel.

A non turbo charged diesel with a vane style afm could run on almost anything for time or a long time.

Probably the only joy I have of running an old Escort van biggrin

I was an Esso tanker driver at Bowling, west of Glasgow. In those days we loaded the trailer standing on top of the tank trailer. Having several "pots" in the same truck, we would deliver red diesel to a school oil fired heating tank and then petrol and white diesel to roadside petrol stations on the same run.

The loading gantry at the terminal supplied petrol, white diesel (and Jet A1 for Glasgow Airport). The white diesel became red diesel at the loading gantry above the trailer. There was a 20 litre cistern in the roof that dispensed highly concentrated red dye via a dosing valve into the white diesel loading pipe. Every so often the on-site Customs representative would arrive unannounced on top of the trailer to check the quantity of fuel loaded with dip sticks and take a sample of red diesel from the trailer pot to test it had the correct concentration of red dye.

I was expecting a tale of when you turned petrol red smile .

My irrelevant tale ...

I've heard of units taking 15 tanks on exercise and allowing a few to just idle the engines while the others did some hard graft. Of course, an idling engine uses less fuel than one shifting 70 tonnes of metal over rough terrain. At the end of the weekend, all the tanks had used the same number of litres per hour. Strangely, those with smoky engines in their cars didn't need to refuel at Tesco on the way home wink . I'd like to emphasise that this is only hearsay and has nothing to do with why my old Montego was never the same after a trip to Tidworth.

Hi, my first posting and a second restart of this thread. I've mused quite a bit over heating oil in a diesel engine and have read many inputs on the internet, this thread has gone the way of other discussions. Some are for and some against. I take on board the lubrication issue but isn't that similar to a 2 stroke petrol engine? Put some oil in the petrol and ... no problem. Has anybody tried putting say 10:1 or 20:1 engine oil in the heating oil?

BTW as an aside an alternative would be to use what some call 'black diesel' ... old engine oil diluted with about 15% petrol. The reason why I've not tried the heating oil option myself is that I use black diesel in my lawn mower and tractor. I find a call for old engine oil in my local facebook page keeps me well supplied, some so keen to get rid of it they deliver it to me! smile
