used engine oil

[cfrizzy]

we had a delivery to the site the other day and I was helping the driver unload and as I did I got talking to him as you do, and he was telling me that he gets used engine oil from a garage mixes it with diesel to thin it then filters it before putting it into his escort diesel van, from what he was telling me it runs a treat on it with no smoke, just have to keep changing the filter more often.
apparently its done alot in america just wondered what anyones thoughts are about this

[charvell]

dont think its legal ove here mate. Had a friend of a friend do it he got dipped at roadside and got fined. check the revenue and customs web site out it might tell you on there

[dieselboy]

I thought that this was bad because the engine oil pics up particules which then are air bourne out the exhaust. Of course, I could have dreamt this whole thing and could be completely and utterly wrong. So, just take no notice and pretend I wasn't here

[cfrizzy]

I did think it sounded a bit iffy when this guy was telling me about it but thought it could be worth mentioning.
the other thing I have been looking at today on the difflock site is adding about 1/2 litre of 2 stroke to a tank of diesel there is alot of talk of mpg gains and better running, could be worth a try

found this on another website, does anyone have any comment on this one? I believe adding of 2-stroke oil is a regular thing in the States.

Due to the pollution control measures of the EC diesel-oil is nearly sulphur free and contains up to 5% of bio-diesel. Sulphur has the property to grease the high pressure injection pump and the injectors. Without sulphur, the reduced greasing property of the new diesel has already shown negativ impacts on the long-term stability of the injectors and the high pressure pump. The pump manufacturers have tried to react by lining the moving parts of the pumps with teflon or other suitable material. However, the long term stability is still not achieved as with the old (sulphor contained) diesel.

The engine-research centre of a well known German car manufacurer has conducted some long term tests of diesel additives to find out whether any one of them will have an impact on the long term reliability of the diesel engine components. This introduction to explain were my information comes from.
The results of this research: any diesel additive of any manufacturer presently on the market is not worth the money!

BUT: 2-stroke oil, which we use in our motor saws, lawn mower or in 2-stroke motor engines has shown to have an extreme positive impact on diesel engines, if such 2-stroke oil is added to the diesel in a homoeophatic dosis of 1:200. In practical terms: 0,300 litre of 2-stroke oil into the 70l diesel tank. The 2-stroke oil will be absorbed by the diesel (emulsion) and grease every moving part of the high pressure pump and the injectors.

Besides this, the 2-stroke oil will keep the diesel engine clean, as it burnes cleaner as the diesel itself.

In other words, the 2-stroke oil has a much lower ash-content as diesel, when burned. This proven fact delays the DPF (diesel particulate (soot) filter) to clogg, and the "burn free" process of the DPF will be much less.
One more information: in Germany we have to present our cars every 2 years to the TUV -Technical Supervision Organisation - who will check, amongs others, the pollution of petrol and diesel engines.
The measured cloud-factor of a diesel engine without use of 2-stroke oil has been 0,95.
The same factor with the use of 2-stroke oil has been 0,47 - reduction of nearly half of the soot particles.
Besides this, the use of 2-stroke oil in the diesel will increase the milage by 3-5%.



I also dug this up from another forum, apologies for plagiarism to the original author.



I did a lot of reasearch on 2 stroke oil in diesel engines.

It seems our american cousins are already wise to the benefits of a drop of 2 stroke oil.

Anyway the science is well proven , it burns more completely than diesel , reduces engine smoke to virtually nothing , cleans the combustion chamber , it appears to lubricate the egr valves to close more evenly.
(I had a lazy egr valve one side but it's not lazy any more)

You can buy 2 stroke oil cheap enough on ebay , from wilkinsons or b+q.

I've used it for a few months now in my RRS and the wifes A4 tdi.
Much quieter when cold ,much better throttle response . no smoke unless I drive like a test pilot when I get a light haze from the pipes instead of the smoke I used to get.The throttle response is thebig difference.
It is more lively and the gearbox doesnt hunt up and down at all.

just 300mL of 2 stroke oil in a full tank really does give you wings.

I've got my dad using it in his Mitsi L200 navvy wagon , same story.
Neighbours ford focus , different motor!!
Mates escort diesel van 1.8 , much smoother +quieter.

Any questions ask away , I've had such success I thought it was my duty to report it.

I've done a fair bit of research for bulk buying , I wont post it as it might be construed as commercial posting.

It's such a small percentage of the full tank it can do no damage and dissolves completely.

I dont see how we can lose.

Think I will try it when I can next afford to fill the tank!

[cfrizzy]

I bought a litre this morning and bunged half of it in on a tankfull shouldnt do any harm so I thought I would give it a try.

So REDUCING the specific impulse of your fuel (albeit by a tiny amount) INCREASES how far it takes you? O.... K....

Try snake oil next?

weeeeeellll........ you are reducing the cetane rating, but as 2 stroke oil is used as a lubricant . We used to have lead as a petroleum lubricant. In the same way we have a much reduced availability of sulphurous diesel. When you crack crude into its constituent parts, you may find that the heavy oils have a high sulpher content. this has been exploited by manufacturers, to lubricate things like injection equipment. when you heat the sulpher. you you get co2, sulphurous free radicals and sulpher dioxide...or acid. by reducing the cetane rating, but increasing lubricity AND cutting down on the sulpher output, you should, theoretically burn cleaner....theoretically. I suppose it would take a lot of usage and data collection to figure out any benefits.
