I used to get around 29mpg with my 1.4 petrol, 8L=60 miles, I mostly do urban driving and ~15/20min drives, so meanwhile wasn't great mpg, it was okay.
Last month it has suddenly gone to 23mpg, 10L=60 miles, which is bad, especially it's summer time. I mostly drive the same distances too.
I'd changed the fuel filter, still the same.
I didn't notice any change with the car, the oil consumption is very low like before, reaching coolant temp like normally. I'd used valve/piston cleaners from time to time for years and cataclean around 4 month ago.
Any idea what to check? The spark plugs are 4 years old, I'd checked them last year and looked fine, battery is 6 months old.
Thanks
