Question

How do you make home-made fuel for your car that is environmentally friendly (i.e. using old veg. oil ect.)?

Answer 1

I'm amazed at the BS put out on the subject...? where do u get gallons of old oil...all the fast food places i know get paid by a renderer ..they go from restaurant to rest.picking it up...its not just free for the asking,,,its also a mess,,,unless u set up cleaning and storage in garage,,, and anything that burns produces carbon emissions...a lot of trouble for no gain in my view.

Answer 2

IF you have a diesel car, then you need a kit, approx $800 from greasecar.com, and then you can put filtered vegetable oil in the 2nd tank.  The kit costs about another $800 to install.

Answer 3

This works only with a diesel engine.

Answer 4

Filter the heck out of the used veg oil (get only oil used to fry non meat stuff). Once its filtered dump it in the tank of any old diesel car and if the temps are above 60 it will run just fine in an emergency. If you want to make this a habit then get a second tank put in splice the fuel line just before the fuel pump with a switchable valve, start your car on diesel let it warm up, switch to veg oil, before you get to 10 miles of your destination switch back to diesel.

It helps if you can prewarm the veg oil via a heater (if you are using a twin fuel sys, then you can use the radiator heat via pipe etc).

There are variations to the above process and some go pure veg oil with electric heaters etc. (when oil cools it thickens). See web site and others like it.

Answer 5

i think you have to get a mechanic to change your gas tank in some way so that it can take other things....then you can just dump the vegetable oil in how it is

Answer 6

The kits from greasecar are for burning straight vegetable oil. You would be better to make the oil into biodiesel by treating it with lye and methanol.  Biodiesel can be used anywhere you can use number 2 fuel oil.  I have used it in my oil furnace for three years with no problems. It can be used in an unmodified diesel engine.  Vegetable oil does have one major down side. It gels at about 32 degrees so it is not a good fuel in the winter.
