Anyone ran their car on cooking oil

Potentially. The main thing is that it is thicker than diesel and can have problems with clogging if the weather is cold. A blend of oil and diesel would be better.

Yes, it does have a distinctive smell.

Technically, not - as you're bypassing the tax paid for regular fuels.

Probably. Diesel logbooks simply show 'heavy oil' as the fuel type, and I'm not sure if there is a technical difference between using sunflower oil/diesel mix and fuel sold as biofuel.

Depends on the engine. Some cars run perfectly on it with not issues what so ever, others will get trashed by just one litre of veg oil. Do some research into it.

A little bit, also smells like a bbq abit too. Better then the smell of diesel.

Yes perfectly legal to use. If you use less then 2500ltr per year then you dont have to do anything. If you use more then that then you have to register with HMRC and pay the duty on it.

Yes. In fact aanectodatally a fully operational car running on veg oil will as a rule produce lower emisssions then on standard diesel fo the mot.
