Hi, probably worth a new topic but incase something I've done here is relavent- I thought it worth mentioning.

My fuel consumption seems super high. I drive very conservatively (no hard accelerating).

Maybe this is normal, but it seems my fuel gauge is dropping super quickly.

I'm getting roughly:

18 liters per 100km / 13Miles per gallon


I am using P98 fuel (highest here in Australia)

Could it be because the fuel was sitting there unused for 6 months?

Is anything I've done likely to have caused it? The mechanic told me I've got a few air leaks, and my CCV needs to be done again. Is this likely to cause inefficiencies?
