How much difference can it really make? It feels like my instantaneous MPG readout is broken, does it take time for it to readjust?
Sitting at 60mph with cruise control on with a warmed up engine it was sitting around the 75mpg mark which I find hard to believe... |
Go off your average mpg, not instantaneous. Even then, I’d take the readings with a pinch of salt. Its very rare that they’re bang on accurate.
