Just been to my local tesco (cheetham hill, manchester) when i saw stacks of 20l containers of vegetable oil. it had £15 on the box so i picked one up. i saw a lady walked passed with 3 and she said what a great price it was £7.50 so i went back to the pile and there was a sign saying was £15, now £7.50 so i got 2 more so i have 60 litres for £22.50.
dont know if online or nationwide but definitely £7.50 for 20 litres in my tesco.
Anyone intending to use this in their car - remember you will destroy your engine or oys components if your car is unsuitable.
Do some research first.
