    i went on a few different websites and i keep hearing both good and bad things about converting to veggie oil... make sure it has no perservitives etc.. and its better to go with 70% diesel and 30% veggie oil. but nowhere does it say how i can do this or where!

    so i have two questions:

    1) How do i convert? do iget a new engine? do i buy new parts etc..

    2) Where is the nearest place to get this done? (i live in northern delware)

    i would love to have the potential person converting my car to answer some common questions i might have i just have to find him. most of the places i do find are on the west coast or as far as florida... i can drive that far.. if you know of anything please let me know threw here or message me =)

    • Start with a modern diesel engine. Nearly any newer diesel engine can be converted to run on vegetable oil as long as it doesn’t have rubber seals in its fuel system (only older diesels use rubber seals). The rubber seals will deteriorate when exposed to vegetable oil over time because vegetable oil acts as a solvent.

    • Install a vegetable oil fuel conversion kit or have a mechanic do it. You should keep the original gas tank to hold regular diesel or biodiesel fuel for cold weather. Install a second tank for vegetable oil; these sometimes go in the trunk. The conversion kit should include hoses from the car's radiator to the vegetable oil tank to heat the oil via a heat exchanger before it enters the final fuel filter and injectors inside the engine compartment.

    • Get vegetable oil. New vegetable oil is easiest to acquire but very expensive. Restaurants will often give you their waste oil for free. Chinese and Japanese restaurants are best because their oils comes out cleanest. The oil should be amber in color. Oil from other types of restaurants may also be suitable but could require more filtering to remove food particles. You will need a few containers for transferring the oil from the source to your filtering destination. The five gallon jugs that the restaurants receive the fresh oil in work fine. Restaurants are usually happy to give you these containers since it saves them disposal fees.

    • Filter the oil. Use filter bags that are rated to 0.5 microns thick. To increase the life of your filter bags, first allow the oil to sit in a barrel for about a week to let particulate matter settle to the bottom. Then, pump or scoop the oil into a filter bag suspended above a fresh empty barrel from the top of the barrel (since most of the food particles matter and possible water is at the bottom). Start your engine using regular diesel or biodiesel fuel from the normal gas tank. Once the engine and vegetable oil are warm (after about 15 minutes depending on weather), switch to allow the vegetable oil to flow into the fuel source.

    • Switch back to diesel or biodiesel a few minutes before you stop your engine for any time (about 10 minutes depending on the temperature) to make sure the vegetable oil is purged from the fuel line and injectors so that they don't become clogged when the engine cools.

    google: vegetable oil fuel conversion kit, or look at greasecar.com
    as for where to get it done. i have no idea. u can buy kits on the net. got any restaurants around, i'd ask them about they're oil disposal.

    theres places in pa ny and de that do conversions but u can do it yourself
    the best is not a 70/30 mix if u want to run straight veggie i think thats best

    best method is a dual tank
    1 small tank for deisel to get it running, and up to temp .you want the cooling system to be connected to a heat exchanger in the second tank to heat the veg oi
    u want fuel lines that have the fuel go thru an inner tube thats surrounded by a outter tube of coolant to warm the lines
    u want heated heavy duty fuel filters
    prefferablyt 3 in a series
    and u may or may not need a stronger lift pump ajnd bigger injectors

    last thing u want is a guage measuruing fuel temp an fuel tank switch


    when u shut it off u also want to switchy back to deisel to clear the lines

    theres thousands of sitres if u google swo/wvo conversion
