used engine oil as Fuel? - Chris_90 - 31-01-2014
Not sure we're to put this thread so thought I would ask here
So seems that people keep telling me I'm wrong by saying using used engine oil is illegal?
So is it legal or illegal?

Illegal you're car will get seized
RE: used engine oil as Fuel? - adamm306 - 31-01-2014
why would you lol
RE: used engine oil as Fuel? - powerandtorque - 31-01-2014
Given that I don't think that it's covered under the same excemption that veg / bio oil is, I would imagine that it is illegal to use as fuel on the public road unless you pay the appropriate duty on it.
Don't see any reason why you couldn't quite legally use it for off road use though, much like red diesel.
RE: used engine oil as Fuel? - THE_Liam - 31-01-2014
It's not duty paid, so if you get caught with it they could give you a bill for the duty on how much they think you've used...
However, I have it on good authority from a friend that an XUD runs amazingly on it

might not want to run it straight :p more likely to get pulled for the billowing clouds of white / blue smoke than suspected fuel duty evasion
RE: used engine oil as Fuel? - Tom - 31-01-2014
Sad how vat was was paid when whoever bought the oil, but to use it as fuel you have to pay more :/ But yeah i put it in my xud whenever i do an oil change just dump it in the tank with whatever else was in there, dont even notice :p
RE: used engine oil as Fuel? - Danny2009 - 31-01-2014
I ran about 100l through straight in tank was fine free fuel
RE: used engine oil as Fuel? - Piggy - 31-01-2014
Really...does it smoke like hell?
RE: used engine oil as Fuel? - Danny2009 - 31-01-2014
I expected it to cover the street in blue smoke but no it was fine obviously smelt like valve stem seals was shagged but it is burning pure oil.
Runs loads better than veg Dosent gel up and no lumpy starts/cutting out at junctions
RE: used engine oil as Fuel? - HDIkyle - 31-01-2014
I always put mine in from oil changes but not usually straight
RE: used engine oil as Fuel? - Danny2009 - 31-01-2014
I'm a mechanic so have shit loads of oil from services gearbox oil from clutches pas fluid removing engines ect
Got 60l saved up ATM need to buy something that will burn it again when I got a little more saved up
RE: used engine oil as Fuel? - Ruan - 31-01-2014
I know this from field cars and the legendary transit drifter.
It does run, yes..
It's a total arse to start from cold, oil doesn't atomize well when it's thick.
It gums up injectors.
It is 100% illegal to use on the road, no duty paid and no exemption.
Smells pretty horrific.
Drops power by at least 40hp.
Do not even attempt gearbox oil or diff oil or similar, doesn't burn, you end up with solid oil running out the exhaust.
If it's got any bits of bearing in which it inevitably will from general engine wear, it'll start wrecking the pump.
It doesn't cause blue smoke like you think it would as it's being injected at the correct time in the correct quantity... But it does haze especially on idle of the temperature isn't up, it just can't combust.
So all in all, yes it does run, but not well and is likely to shag the engine after a while - not to mention it's totally illegal to do it..

What Ruan said.
I run all my offroad vehicles and boiler off it.
It will work, but i wouldnt think about doing it on the road..its totally illegal..fairly smokey...and even though i couldnt recommend it more in old field cars etc..I wouldnt dare put it in my road car! it WILL detroy your pump / injectors in the end...whatever you do make sure you have good filtering if your running it..end of the day engine oil is FULL of tiny bits of metal...
But as OP asked, yes, they will run fine, infact once warm you will barely notice any difference, it works better than veg. but its doing nothing any good at all...
All the videos on my youtube of blown fields cars are all running on 100% waste motor oil.

That HAS to be Sam...
my 1.5D TUD runs on it
it's a pain in the arse filtering it though.
RE: used engine oil as Fuel? - Chris_90 - 31-01-2014
I don't have no plans on running it was just wondering if it's illegal or not
Thanks
RE: used engine oil as Fuel? - ally406 - 01-02-2014
Yes, illegal unless you find a way to pay duty on it. I tried it back in 2007 when duty was not payable on this fuel type. Bit of a bastard to start, but once running, I thought the engine actually had more torque (this makes sense, engine oil has a higher energy density). It burns a lot cleaner than some hysterical types will try and tell you, however there are many issues to consider like injector coking and metal particulates. It seems to be more common place in the US and centrifuging seems to be the way to do it (so called "black diesel"). If I didn't have a good source of WVO I might investigate paying duty to HMRC, you could still end up with fuel around 50ppl, and last time I looked, garages were delighted to have you take it away free of charge.
RE: used engine oil as Fuel? - n0v0s - 04-02-2014
mix 10/20% petrol to the engine oil and leave it for a while. Most of the free carbon / sludge mix will drop out. Then filter... Will run fine and save the pump. However, Chances are you will be poisoning yourself unknowingly from leaking manifolds and toxic gases seeping in to cabin.

What you thinned that out with? Is it ok in Ireland then?

It's illegal over there too, but you can see the car in that pic is off road use only.
