View Full Version : For those lucky enough to drive cars that can use veggie oil
Tesco have an offer on for 3 litre sunflower oil at effectively 50p a litre.........................
wow thats cheep, diesel engines do need to be adaped right?
YES diesel engines need adapting! "From the Fryer to the Fuel Tank" by Joshua Tickell lis probably the best book you can read on the subject.
Actually, mine hasn't been adapted at all. It's a Ssangyong Musso with a 5-cylinder Mercedes 2.9 turbodiesel. Many in the Ssangyong Owners club run veggie oil (sunflower is best -DON'T use olive oil!). In winter its advisable to use a diesel/veggie oil mix as otherwise there can be starting problems because of the viscosity. You can install pre-heaters etc, but not worth the trouble in my book - just run 25-50% diesel.
However, its NOT a common rail diesel - those don't take kindly to veggie oil at all!
It's when you go down the route of using used oil that the problems arise, trying to filter out all the black bits and dissolved fats which will clog the injectors and fuel lines.
I have been kicking myself for selling my Mitsubishi Delica 2.8Td a couple of years back seemingly they dont need any adjusting , especially when the price of fuel is rumoured to rise by upto 30p a litre by the summer .i still have a diesel honda ctdi and an old smiley transit,does anyone know if they can run on veggie oil?
does any one know if you need to make adjustments to a Suzuki Grand Vitara 2.0TD to run on veg oil, or can i mix it 50 / 50 with regular deisel ?
thanks for any help.
I don't know about the specific models referred to, but if you join the relevant owners club you'll get your answers there. Or there may be a group online that specialises in veggie oil for diesels.
(Or buy a Ssangyong or Daewoo Musso diesel or turbodiesel - I know those work well with veggie oil!)
Toyota Surfs and 4-Runners work perfectly well on vegoil :D
I'm driving around smelling like a barbeque at the mo' ;)
im not too keen on the idea now after thinking of what happens to chainsaws when you use vegy oil in them (seperate tank for lubricating the bar and chain, not the fuel tank!). at work for many of our contacts we have to use this bio degradable oil which is basicly vegtable oil with added preservatives to stop it going moldy (still does after a while) and it leaves a thick gunky residue in the tank and all other asociated parts after a while. luckily i borrow work's saws not mine because you wouldnt catch me useing it! as its lubrication properties are pretty poor compaired to regular oil. this wears out guide bars, chains and sprockers twice as fast on top of the huge cost of this bio degradeable rubbish!
anyway... im not certain what type of vegy oil it is made from but i can imagine the havoc it could cause in an engine. fuel filters, pumps, injectors, valves etc. also vegy oil cannot be pure fuel so it must make some dirty fumes?
I think we're talking about two different things - I presume your chainsaw is not a diesel? As for fumes, club members report substantially reduced emissions at MOT time, so bonus there too! And you seem to be using your veggie oil as lubricating oil - that's certainlty not what I'm talking about. Veggie oil replaces the diesel, not the 20-50, or 10-40 or whatever engine oil. It would be pretty hopeless for that (as would diesel) - I can't believe anyone actually tried to use it for this purpose!
As for residues, none reported so far by Ssangyong club members, and they've used this fuel for 10s of thousands of miles. (This is with fresh veggie oil though - used oil has all sorts of problems and I'd always avoid it like the plague). I've only done about 3k miles so far on mine, and report no issues, and in-line fuel filter is still spotless! However, I will make sure to change my normal engine oil at 4-6,000 miles
Used to use SVO in my Pajero. Rule of thumb for SVO use- if it isn't common rail or pump duse and has a Bosch fuel pump it should run without ANY mods.
Remember the diesel engine was named after the Dr Diesel that invented it to run on peanut oil. The petroleum companies invented what is now called diesel as a cheaper more cost efficient fuel- how ironic is that?! Since that day though the engines and fuel have become more refined so now it's the older technology that wins out and can use SVO. FYI it dropped my smoke emission from borderline on diesel to being thrashed to death by the tester 3 times as the reading was so low he thought the machine was faulty.
The only possible problem is initially - apparently veggie oil can stir up a lot of sediment in the tank the first thousand miles or so, so its a good idea to put a secondary fuel-line filter in if there isn't one already. If there is, keep a close eye on it and be prepared to replace if necessary. These are dirt cheap though - I bought 10 for a tenner off ebay! (not needed as yet...)
I've run my 200tdi Landrover on veg for a couple of years or so now as many do.....
There are a couple of ther things worth mentioning......on start up when the veg is and engine is cold, unburned residue in the cyclinders work it's way into the sump....not a huge pproblem if you change you're engine oil a little more frequently.....guess what i do with that engine oil after I've filtered it....
also, in the colder months I use petrol to thin the vegoil instead of just diesel.....why? well petrol is cheaper than diesel and its thinner too, so you don't need as much.....I believe you can add up to 10% petrol to the veg oil but I only ever add 5% to be safe and then add diesel if needs be.
I also like to run at least a quater of a tank of neat diesel throu the system periodically....this has two effects, firstly it helps clean any residue build up out of the system and I usually put injector cleaner through at the same time.....the other benefit is to ensure any seals though out the system IP pump etc are lubricated correctly, veg oil doesn't do this, they are designed to be lubed by the diesel.....none of the above are major issues but doing so at intervals you are happy with give a certain peace of mind. It's also worth noting that every engine is different, and may run better with adifferent mix or more regular cleaning as outlined above.
There is an extremely good site including forum for veg oil and bio users which is "the" place to go in my opinion to have you're questions answered re other makes and motors.....www.vegetableoildie sel.co.uk.....check out the discussion board.
