Can a normal diesel car run on cooking oil without any modification done to the engine?

i.e. new and used cooking oil, vegetable oil, used fish %26amp; chip oil from the local chippy etc.Can a normal diesel car run on cooking oil without any modification done to the engine?
Yes, it can, it will run very poorly though. You need to clean and dry the oil first (not gonna go into the details again) and then heat it to at least 160 degrees F.Can a normal diesel car run on cooking oil without any modification done to the engine?
I doubt it if that was the case why would we waste our money on expensive gas and just use oil?!?!?!
no but you can use tractor diesel thats way cheaper than the usual stuff
Yes it can, needs to go through a sieries of heaters so the oil is thin enough, then has special filters to achive the correct microns to pass through the injectors. Will only work through a diesel engine not a petrol engine.


There will be time wher farmers will grow their own fuel, and will be then sold to the public.
Yes. Just pour the oil directly into the Intake. But if its used cooking oil, It must be strained of its impurites first.
