Hi, all.
We had a big family gathering at the weekend, which involved several fondues.
Consequently, I now have several litres of used groundnut oil for disposal.
I was considering pouring it into the LR Discovery's diesel tank, at a ratio of say 2 litres waste oil to 80 litres of real diesel.
Or if I was shy of that, then into the 500 Litre tank of our big generator at work.
Comments?
OK on TDi200 & TDi300, not too happy with TD5 as it's semi common rail. However at that dilution it'd probably be ok anyway.
AWEM
OK, I don't know about the designations. It's a 2006 Disco3 V6 2.7ish Turbo-Diesel.
I don't know the details of how the injection system works.
I may play safe and dump it in the Agrekko genny 500l tank anyways, it sucks fuel at a furious rate.
Do it at the start of a long run. And give the machine a chance to clean itself with a drop of the good stuff afterwards. How did you filter it?
Gravity.
I let it sit overnight, and decanted it like a fine wine.
We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Ron Lowe saying something like:
Filter, filter, filter. Down to 5 microns, if possible. No problem with running clean, dewatered waste veg oil in an older IDI or even DI system, but I don't and wouldn't do it on a modern CR system.

I have a 2 cylinder Lister on a generator, what are your thoughts on cooking oil in that? Not that I have a lot of it, but it would be good to find a use for the old stuff. How easy is it to filter down to 5 microns? Start and warm up on diesel first or is their a %mix of derv and cooking oil that is OK?

Jeez, they'll run on anything.
Easy in the first stages, coarse filtering can be done with cloth doubled or tripled over; requires actually buying a filter for the final ones. 5 micron filters aren't hard to find. At the end stages you really need to start pumping it if you want it within a reasonable time.
For a stationary engine I'd start and stop on diesel, and for normal running, 100% vegoil will be ok once the engine and fuel system are up to temp. If this is in an unheated outbuilding or outside in the winter, a heated fuel system is a must for the vegoil pipery. Of course, it will run perfectly fine on a 50/50 mix in the summer,
60/40 (dino/vegoil) in the winter, but be ready for unreliable starting in the winter.In message , Grimly Curmudgeon writes
Thought that maybe the case. :-)
I'm not that desperate, not yet anyway, so it won't be heated. Be good to feel a bit "green" though. The smell of the exhaust should "interest" the neighbours too.
OK thanks for that, I'll start thinking about change over taps.
At the Golf Club I was a mechanic at a few lives ago we used to run 4 cyl Massey 235s on a mix of 60% chip oil (From the restaurants) mixed with 30% Dino and the last 10% was a drop of 4 star. Mixed up thoroughly in a 45 gal drum, left for a week to settle and siphoned off to a clean 5 gal plastic drum.
Filter?....... That's what the inline ones used to do innit?
As a low revving DI engine they ran well, and I only changed the filters annually to nothing lost on performance or cost.
Got some increased patronage at the restaurants though as the chippy smell used to make the golfers hungry ;-)
We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "Me Here" saying something like:
Oh yes, that's a good point. I mix in a cupful of petrol (boosts the cetane rating, supposedly) and a cupful of ATF (keeps injectors clean) every 60L batch.
I find settling is a good and cheap way, if you've got the time, but the inline filters on many cars and vans aren't cheap, so pre-filtering is best.
That's the Ford/Jaguar/LandRover/Peugeot/Citroen common rail V6 diesel engine.
Fine. It's not going in the Disco.
It's done, 3 litres in the big generator, diluted into 500l of red diesel. This big engine has a mechanically-driven injector pump with a series of pipes coming out of it distributor-style to the individual injectors. Looks like all old diesels to me.
Filtering will be handled by the in-line fuel filters.
