I doubt the HMRC would ever pursue anything unless you were using the vehicle for business use, taxi, delivery's etc. In a 306 DT you would roughly get 25,000 miles out your yearly quota of veg oil. If you cover less than that in a year then i wonder, would MOT certificates be acceptable as proof of usage as it displays the vehicle mileage.?
