nice to see you back here Mr CharlesY, your words of wisdom have been missed
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.
