I'm getting a bit concerned about my focus and its petrol consumption. I put £20 of sainsburys unleaded in and I got only 120 miles urban driving a mix of 30/40/60 roads. I drive smoothly and change up in time and am gentle on the left foot yet this seems a bit rubbish.
I did a bit og googling and it says the AFM may be at fault. I only have a maxiscan ms509 (autel) it shows live data and shows the AFM (air flow meter) at 0.0077 no idea if this is a good or bad reading ?
Could this extreme heat cause more petrol consumption. I am not using anything else in the car like air con etc its just basic driving, although all windows are open so I guess that doesn't help.
Correct tyre pressure aswell. I guess super market fuel is not the best but to be fair I use it usually and get 370 out of a 55litre tank if I'm lucky more than likely 350 urban and 200 miles motorway driving.
Any ideas what else I could have a look at or do ?
thanks Hope you all enjoying this heat, its a bit much for me so I'm hiding inside :)
