I think it's fuel.

Im not very far in but my MPG calculation test didnt last long on Vpower!

200 miles in, weird no power-not-quite-limp-mode issue comes back.

Next fill, I stick in some Tesco fuel - all ok.

Next mpg test, BP ultimate, 600 miles no issues

Next BP standard fuel, 600 miles no issues.

Next, Shell city diesel - 600 miles no issues, mpg recorded - difference felt in engine noise but power feels down, yet less clattery, doesnt shift down a gear as quick.

No issues on normal fuel but still, even the types of fuel for 300+ miles is noticable.


Im now trying to find which fuel gets best mpg for the £, nice to know BP's premium doesnt cause it but vpowers liquid gas does.
