Are there any downsides with converting my diesel truck to run on vegetable oil

that i get at a restaurant? I am looking at getting a diesel truck and converting it to run on vegetable oil that I will get at any local restaurant for free. I've heard that they are just as good as regular diesel but I was wondering if there are any downsides. Thanks!

One of the weird things that i saw on dirty jobs about that is that the exaust smells like the food they make. So the guy on dirt jobs got his oil at a taco place. So his exaust smelled like tacos. But that may not be a downside to you. It may not be as powerful. But it should be fine. You should look into it though.

The only downside is that the motor has to run at a slightly higher temperature than usual, but not much more, but other than that it will probably be better because there won't be as much carbon build up... and you'll always smell burgers and fries!

no this has been done by quite a few people and works perfectly well.
cost to do it will be recouped eventually.
and if you don't mind the smell of mc donald or kentucky fried chicken coming out of your tail pipe, you will be fine and green!

its better than regular diesel. you get better fuel economy AND better performance!!!


but here's the big downside, you have to refine the vege oil. you can't just put in straight vege oil because there are some chemicals in the oil that will contaminate your fuel lines or something. you also have to change your rubber hoses to something else because biodiesel and rubber don't work well with each other.

also, biodiesel starts to gel at higher temperatures than regular diesel, but the temperature is only like 10 degress.


but then there are some places that sells biodiesel...but it won't be free.


if you know how to refine vege oil into biodiesel, i'd say to go for it! you'll save money, the enviornment, and you'll have a much more powerful truck!!!
