    Icon5 Experiences with Vegetable Oil Diesel in Old French Cars

    Anyone had experience with using Vegetable oil from Fish n Chips shops in an old Peugeot Diesel?

    I am guessing that Vegetable oild would cause havoc with a new Diesel. What about old 504s or 405s?

    It seems like an interesting thing to experiment with.

    Quite a lot of the to-and-froms use "WVO" in Xantia and 306 diesels.

    They are fussy about DIY bulk filtration, preheating and the type of injection pump (I can never remember if it's Bosch or Lucas that is unsuitable). Also a noted relatively frequent occurrence is clagging of the pick-up screen with gelled heavy oils. HDis and newer, aren't going to be happy.

    Do you want to deep or shallow fry them?

    Welcome to AF.

    There are some people around and especially a guy in Sydney who has done extensive work in this area. He ran/runs his 405 diesel on fuel he distils from chip oil. I wonder if seagulls follow him?

    The injector pump is the critical part.
    When I was looking into running a 504 diesel on biodiesel I found warnings not to run WVO if the car is fitted with a rotary injection pump. Apparently the extra drag will shear off the drive on the Rotodiesel injection pumps in 504s. In line injection pumps were said to be ok.

    If I put the oil from any of our local fish and chip shops in ANY car would spit it straight out at me!
    I might act like an idiot, and I might look like an idiot, but don't let that fool you: I really AM an idiot!

    What does "to-and-froms" mean?

    My nick name used to be seagull so I had better investigate this further.

    As I recall from my student days there were many fish and chip shops in the North of England that fried in Diesel oil.

    Taste that bad did they?

    Even though the emphasis these days is on healthy polyunsaturated oils a lot of "fish and chip" shops prefer to use animal fat. The most popular being "Frytol". Their justification being that the fried product drains better and the customers prefer the taste.
    Even when a shop uses vegetable oil for their frying it becomes contaminated with fat over time.
    Long gone are the days of shops peeling and chipping their own potatoes.
    Chips these days are purchased precooked and frozen.
    And what are they precooked in? Animal Fat as clearly stated on the label.
    I like to make my own chips and cook them in peanut oil.

    does the animal fat make the oil unsuitable for conversion into biodiesel, or just add some complications?

    Just further complications.
    The fat is harder to convert usually requiring a higher percentage of "methoxide" (sodium hydroxide dissolverd in methanol) and a longer processing (mixing) time.

    Biodiesel made from fat has different characteristics than that made from vegetable oil.
    It has a higher cetane value which gives a quieter engine, not so much diesel knock.
    Unfortunately it has a higher "cloud point" (gelling") so in winter it can cause filter plugging unless there is an inline fuel heater fitted.

    Most biodieselers try to source used vegetable oil.
    One of the best is Eta Salfry, a mixture of soy and canola oils.
    It processes very easily.
    Have done a bit of research on biodiesel, worked as a consultant for a rendering company setting up a biodiesel plant and have made biodiesel from all sorts of fats and oils ranging from grease trap waste to butter.
    The butter biodiesel was a lovely drop.

    I bought a 505 turbo diesel from a guy near me in Kyneton (where the temp is often below zero) and he ran it on straigh chip oil from the local chip shop.

    He didn't filter it or boil it, nothing, just had a few 44 gallon drums in his shed full and let them sit for a few weeks so all the crap settled and poured it in. Car had done over 300,000 when I got it and I used it as a tow car for a while and did a few thousand kms and never had a problem. He did tell me he changed the filter about every 5000km and the car had a distint smell about it but never had a problem.

    Lots of accounts of vehicles being run long distances on vegetable oil.
    Also lots of horror stories of sump oil contamination, clogged piston rings, injector pump failure and poor spray from unmodified injectors.
    Some vehicles respond better than others.
    The jury is still out in my opinion.
    Elsbert in Germany produces engines designed to run on SVO and also kits to convert existing diesel vehicles.
    Optimum conversion is a two tank system with heater for SVO.
    Start on petroleum diesel, switch over to SVO when same has warmed up, switch back to diesel before shutdown.

    There was a very interesting account of a journey through the USA to Mexico in a converted VW Golf,on one of the alternative fuel forums. It was titled "SVO to Mexico". Made great reading but can't testify to its veracity.
