I went into the garage today to buy petrol. First I filled two cans for the mower with E5 at £174.9/litre. Then I came to fill the car and the thought struck me that with E10 at £169.9/litre, the better mileage per gallon offered by the E10 would outweigh the 5p/litre difference in price.

Long term, the car has been doing almost 40mpg. Now it is doing 36.3mpg. If I assume I am only losing 3mpg by use of E10, I am still losing 7.5% of my mpg. At £1.70 per litre for E10, plus 7.5%, the equivalent cost of E10 is £1.83. So my E5 at £1.75 was 8p per litre cheaper. Putting it another way, if the difference in cost between E5 and E10 is less than 13p/litre, I am going to be better off using E5.

We were out riding near Cambridge in Gloucestershire on Sunday , and came across a small garage selling 4 star ! I only needed 3 litres to top up, good job as it was £2:30 a litre !

hi E10 unleaded petrol is cheaper than E5 that is known as the super unleaded petrol in London , and the 4 star petrol in Cambridge and Northampton is mainly used by the drag racing boys etc

What ever way, we are still being robbed at those prices, E5 or E10. Shameful.

the oil company's can do what they like and no one in power does anything about it , we are just getting took for a ride
