    Question WGO twin tank conversion?

    Hi I have a 2004 2.0L DTI Vectra and was thinking of fitting the waste veg oil twin tank system to it.
    Has anyone tried this yet who can reply with results on things like how the car is running and mpg on the wvo.
    This is the kit i was looking at:-

    Not sure if this will be any help but.....

    My mate runs his Toyota Hi-Lux on veg oil (2.4 lt) with no trouble. He just buys it in the shop then drops it straight in. Smells like a BBQ from behind though..

    Gets a tad less mpg then he does with diesel...

    Personally, (in the case of Vxl’s DTI’s & CDTI’s at least) I would have great concerns for the life expectancy of the fuel pump if running on anything other than quality diesel, and considering the cost of a replacement, it is just not worth the risk IMO.

    Check this system out as well, its a bit cheaper than the one on the other site. I have read that the main problems are with the lucas pumps, and the bosh type are ok, and the life is extended if the oil is heated prior to the pump. And with the start from diesel 2 tank mod it means the pump isn't trying to force thick wvo through on cold start up.

    link, just - the spaces.

    Good point, he did have to change the seals on the pump, but we thought this down to the age of the car and perished rubber seals.

    thats just the 'cooking oil' way of doing it.. you can convert veg oil into a crude fuel that runs 'better' in the DTi's by brewing it with methanol and caustic soda.. that runs far better and doesn't need the preheater...

    the bottom line is, if it's a CDTi engine folks, forget any form of Bio Fuel.. the high pressure pumps just die.. The DTi's will run on it thou, but don't run neat..blend it to a max of 50/50 bio/DERV and it should be just fine..

    I was under the impression that it tended to rot the diesel pump seals a lot quicker, and that can be quite an expensive fix.. My m8 is running veg oil in his pajero, runs very well until tesco doubled the price of veg oil!. he has new injectors fitted as well which helps, but now it runs fine on veggie oil, but drinks diesel!
