veggie oil burners

[messerschmitt owner]

I have second dibs on Mr Welfare's 405 estate (and hoping I get it) but I was thinking, if a 405 runs on a veg oil mix, does the BX with the same engine (and I assume, Bosch fuel pump) also run veggie?Just asking as I am currently thinking about a 120,000 mile BX 19RD I have seen.

[dollywobbler]

Yes, but expect to change fuel filters on a fairly frequent basis at first.

[messerschmitt owner]

my thinking is 1. changing the fuel filter is really easy on a BX2. Will start off with a 20% oil/80% diseasel mix then build up to 40%/60% over timeHave had three 17 Diesels, a GTi and a 19 Diesel so am used to them.

[dollywobbler]

Should be ok then. Get yerself signed up on BXclub.co.uk and have a search about. Veg oil gets discussed there pretty often. I should get another load for my BX, but I've not managed to get around to it yet.

not all pug/cits had a Bosch pump some had a Lucas CAV pumpthose ones had a roller bearing main bearingif the bearing on a bosch pump wears I think it starts leaking fuel and the timing belt can start to not run trueif the bearing on the Lucas CAV pump wears it breaks up and causes the timing belt to break distroying the engineMy sisters 309 had a Lucas CAV pump that broke up but luckily a piece of the bearing got wedged in the idle mechanism causing it to idle at 2500rpm, which meant that it got looked at before it totally seized up

I worked as a Pizza delivery driver at the end of last year and they had a big drum full of used veggie oil. If I had a diesel, I would've had it as they couldn't get rid of it.

It is this one on the BX forum

Sounding like a complete thick twat here, but I do find it bizarre/odd/incredible that an engine that is basically set up to run on diesel can run on veggie oil. The two products, scientifically can't be that similar, surely? Tsssshk, science eh......

the diseisel was invented to run on coconut oil originally

[j-j]

true, I ran my Xantia 1.9 NON turbo Diseasel on 50%-100% SVO for a year before the price of veg oil went up to (at the time) the same as diesel.It ran perfectly at all times and started on one crank of the starter every morning, even in winter! Had the Bosch fuel pump.I enjoyed tipping veg oil straight into the fuel filler in supermarket crap parks in view of everyone staring - quietly freaking out. Was a good memory but at the time veg oil was still 45ppl out of LIdl - why would you wanna do it nowadaze?

[Milford Cubicle]

It wasn't invented to run on any specific fuel, it was intended to be a multi-fuel engine - running on all sorts, including coal dust with some explosive results.Because of that a diesel can in theory run on almost anything, but what limits them is the increasingly fragile and complicated methods of injection.I think most turbo diesel BXs use the Lucas CAV pump, so a non-turdo will be your best bet, though I reckon a lot of these use the Lucas pump too.

New oil is creeping down in price again, probably about 70ppl in cash 'n' carry type places, and 84ppl in Tesco. A decent saving when diesel is £1.20pplOf course if you can be arsed dealing with old oil it's often completely free.

[dollywobbler]

Because it smells nice!(it was peanut oil that the first diesels used though, not coconut oil (milk?). Well, as far as I know...

yes you are correct good job i wasnt cooking then note to self engage brain before replying

[meggersdog]

I ran my Xantia TD on cooking oil and Kerosene for nine months until the suppy of Kero' ran out.At that time Tesco's oil was 54p a litre now it's 83p or six litres for a fiver.An XUD engine will run fine on waste engine oil aslong as you change the filter every couple of weeks.It does smoke on first start up then it's fine.With used cooking oil I find mixing 10% parafin in thins it enough to cold filter.I use a 10 micron washable sock filter and an inline fuel filter.For waste engine oil I used to use an old fridge with a light socket at the bottom,put a five gallon barrel in and leave the light on and shut the door.Leave it overnight and it's ready to filter in the morning.My Discovery smokes too much as it is so it's on Tesco's finest and the real stuff.

[Cavcraft]

BX with Bosch pumps love 'em and actually run better, quicker and claner with it.

[messerschmitt owner]

must check costco price in 25l drums

Direct injection engines are no use for running veg oil unless modified.

[dollywobbler]

Not sure that's right Milf. Common rail diesels are certainly no good on it due to the massive fuel pressures involved, but direct injection itself isn't a barrier. Pretty sure I've heard of Montegos running on the stuff.

[Lukas]

Old TDI-engines are running on it too.

Transit DIs are fine on it, as long as they have a Bosch pump.

[meggersdog]

Not had a problem in three years running 50/50 mix.I don't put veg oil in during the really cold weather though.Mixing parafin in with used cooking oil keeps it thin and doesn't seem to seperate when left standing.When I ran a Xantia a mate of mine had a Maestro diesel (about five years ago) and upon smelling mine did the same with the Maestro.He was doing 500 miles a week and never had a problem either.

Has anyone else used Millers Diesel PowerPlus diesel additive?I'm using it on the R5GTD (175k miles) and although it still smokes on startup, this stuff has stopped it smoking anywhere near as much after 5mins running. Plus as it's a cethane booster the veg oil isn't noticably smokier or less powerful (I really Like using the word 'Powerful when refering to this car ). No I don't sell the stuff and yes the above is all 'In My Opinion'.

[FredTransit]

Veg oil is actually a higher calorific value than regular derv, and burns cleaner too.

[Milford Cubicle]

Some DI engines are better than others, but still have a potential for catastrophe that pre-combustion chamber indirect injection diesels don't suffer from unless seriously neglected.This is coming from someone who blew up a Rover 220Di finding that out...

[jonny69]

Glad someone answered my question about using old engine oil. I figured it would work even if you just tipped some into the existing fuel.What about waste paint thinners and old gunwash in with the oil? Diesels ought to be able to cope with any of that old crap as long as the tank, pump and fuel lines can take it.What happens when you put petrol in with diesel? Not loads of it but say you had some from a drained tank where someone had stuck petrol in by mistake and you added a bit to your tank of oil or whatever. Surely it would still run ok?

[Milford Cubicle]

Older diesels will run fine on a fairly weak petrol/diesel mix, anything strong (more than 30/70) and I think you'll be losing vital lubrication.I've recycled my own used engine oil into fuel and it's pretty grim stuff, it turns the in-car filter black, causes a lot of smoke and must coke up the injectors because of all the contaminates.

[meggersdog]

Before the modern diesel fuel with it's anti waxing properties lorry drivers would add 10-20% petrol to stop the fuel freezing in winter.Anyone remember lorries at the side of the road in winter with a fire underneath the fuel tank to thaw out the diesel ?

[Milford Cubicle]

The diesel in the school buses regularly gelled in the winter here, no fires required - just no school. :DI'm not sure if diesel sold in the UK has any anti-waxing properties, plenty of diesels broke down when it was down to almost -30 here.
