Well....let the tank run down to 1/4 today then filled up with Shell vpower.
1.32p. a litre 😡😡😡
Got straight on the motorway and gave it a 50 mile "blast"(Will give it a shorter run every couple of weeks).
Will let you know if I notice any difference in the next couple of weeks.(fuel consumption etc).
Getting about 26mpg at the moment around town.
Sometimes its been as high as 32-36 in the past but will have to wait and see.
25+ around town for a 2 tonne 4wd SUV is to be expected
