Diesel additive, 2-stroke oil?

    I've been following a discussion in the Ford forum, regarding diesel additives. There's been an investigation by a German company and they are saying that most diesel additives are no use at all.

    What they say you should do is add about half a litre of mineral based 2-stroke oil to a full tank, and this will compensate for the reduced lubrication properties of low sulphur diesel.
    Also it will improve economy so they say...but this is always claimed with this type of thing.
    What do people think of this? I tried it in my Transit TDCi and it does seem smoother but I could be imagining it.

    In my opinion, the best doozel additive is vegetable oil.

    Oil is oil.

    your diesel engine hardly cares what sort of fuel it gets as long as it is OILY, and the viscosity is about right.

    Old engine oil cut (thinned) with kerosene is fine, but try to filter it first.

    If the viscosity (thickness) it too high, it may over-pressurise inside the injection pump and damage things.

    You guys with older diesel Landies could be running on free fuel if you work out the knack of old oils, filtering and viscosity, and you will find then performance is good too.

    Hi Sean,
    Kind words ....

    It seems it was an AOL problem shutting me out of some sites without explanation, and Landyzone was one.

    AOL is impossible to deal with nowadays. Ten years ago AOL was about the best, but it has gone completely down the drain.

    I changed to BT last month, and after a month of "negotiations" my broadband speed is now THIRTY TIMES faster than it was under AOL, or under BT to start with. BT assistance has been extremely good. I was amazed. To start with I thought they were winding me up!

    Back to the subject .... real diesel engines with fuel injection pumps and real mechanical injectors will run beautifully on ANY sort of oil, vegetable or mineral, provided that the "cetane rating" is high enough to allow compression ignition, and provided that you make sure the oil fuel never gets too thick. Glow plugs should be in good condition at all times so that starting-up is fast and clean.

    Used engine oil is fine but it would be a good plan to arrange a filtering system for it before tipping it in the tank. The local HYDRAULICS people can supply huge filters that will do the job well. FUEL filters for diesels are finer than ENGINE OIL filters, so even using a system of FUEL filters on the old engine oil would be good, and then you thin it down a tad with kerosene (probably never more than 10%) which gets the viscosity DOWN and the cetane rating UP. Even 5% kero makes a BIG difference to viscosity.

    Discomania and I used up 50 gallons of lube oil from a big factory machine a while back. We thinned it with a little Kero. Discomania tried 10 litres in his 2.5 NA Defender. "Rocket Fuel" he said. So I put 20 gallons in the Disco td5 and hooked on a caravan and set off down the motorway. Wow ... a real blast it was. Super performance. That fuel was soon used up!

    There has been more, and there's no red dye in it.

    Don't be scared to do this, and remember, you don't ned to add it all at once or run on neat old engine oils. It doesn't matter what the mix is, but every gallon of used oil you add to the tank saves the price of a gallon at the pumps, so going half-in-half saves as much in the long run. With most fuels being "low sulphur" these days, adding good lube oils to the fuel is positively good for the injection pump and injectors, which need the best lube going. Just make sure the oil you add is filtered (black is OK as long as it is filtered) and that there isn't WATER sloshing about in it. The black in engine oils is ultra-fine carbon dust (like copier or laser printer toner) and will pass through the system fine, and burn away in the cylinder.

    Just as a matter of interest, you engine oil users might like to know that cutting (thinning) the old engine oil with 10% kero BEFORE filtering it makes it much easier to filter.

    I think most of you would be surprised how many diesel owners are running along good style on used engine oil brews. It is just necessary to make sure you thin it down enough (too much won't matter) and filter it, and get any water out.

    In 1955 during the Suez Crisis (big British screw-up) when there was no fuel (petrol or diesel) my Uncle Hugh had a Merc Diesel that he ran for months on straight ReDeX which was and probably still is a petrol addidtive and upper cylinder lubricant. It went just fine and did no harm at all.

    What's the easiest and best way of filtering the used oil from one 5gall drum to another. Is there some kind of filter you can just put in the funnel?

    a old leccy fuel pump, connected inline with a standard filter + housing should work

    Strictly speaking, Kero is not a duty paid fuel... If they can detect it, I'd say you'd have some questions to answer!

    Super!

    So 8 x 15 litre cans is 120 litres of UNUSED veg oil which is the same as £120 cash to your pocket if you tank it! The 200 tdi is the perfect engine to make good use of this excellent fuel.

    The age of it doesn't matter. I suggest you do a little experiment to settle your nerves.

    Get a 3 litre plastic milk bottle, clean it and dry it, and put a litre of pump diesel in it. Now add a litre of your veg oil. You probably won't even need to shake it to get it mixed. Have a good look at it. Remember, Rudolph Diesel designed his engines to run on peanut oil. Examines your two litres / £2 of oil mix carefully. Then say the magic words .... "What the hell" and toss it into your tank. You just saved £1 cash.

    After this, why not throw in a gallon / 5 litres of your veg for every two gallons / 10 litres of pump fuel? That way you save the whole £1 on every litre, but just over a slightly longer period.

    THIS IS LEGAL - anyone can use up to 2,500 litres of veg / bio every year without a problem.

    By the way, at the one-third mix I suggest, I bet you notice the engine runs smoother, and pulls better. It's quite noticeable. My TD5 runs MUCH sweeter on bio than on any pump fuel.

    Enjoy.

    I've just about used up the 28 sec heating oil that was left in the domestic tank when I installed a gas heating system.
    Ran it 50/50 with pump fuel and no ill effects.
    I've got about 5 gallons of old engine oil which will be getting filtered shortly.
    Am I right in saying I should mix it with 10% kero?
    If this is correct I'll start to fill the old heating tank with used engine oil as and when I come across it.
    CharlseY My mate runs an injection moulding firm that has hundreds of litres of hydraulic oil to dispose of every three months. Could this be used as fuel ???

    what are my options regarding the waste oil into fuel scenario

    cheers in advance
