40 litres of diesel @ £1.43.9
+ 20 litres of new and unused cooking oil @ £20.00
gives the cost of a tank @ £77.56 (this is equivalent to £1.29.3/litre)
Mileage has gone up too 😀 so we now get 690 miles out of a tank before the warning light comes on. This equates to almost 55 mpg, a 10% increase on the best we’ve seen previously, which was already a pretty good figure. Renault quote 48 mpg for the combined cycle, which is usually a pretty accurate figure for the most you can eke out of a tank, despite what Which? magazine has to say on the subject…
So, all in all, my wife and I usually do about 1500 miles or more each month, (we live in the country, so everything’s flippin’ miles away).
1500 miles at 50 mpg and £1.43.9/litre costs £ 196.16 – (13.1 pence per mile)
1500 miles at 55 mpg and £1.29.3/litre costs £ 160.24 – (10.7 pence per mile)
A grand saving of £35.92 a month or 2.4 pence every mile or £431.04 annually. Not bad, considering the car cost less than £600 in the first place.
Perhaps I should put that amount aside every month. So long as the car lasts 18 months with no veg oil related problems, then I think we’re on to a winner…
