2018 Suzuki Cultus VXR fuel efficiency has dropped

I have a 2018 VXR with 85,000 km on it, and lately, my fuel efficiency has dropped to 9-10 km/l in the city, even after regular maintenance. I used to get 17-18 km/l on long drives with A/C, but now Im only getting about 350 km on a full tank. For comparison, my 2020 Cultus VXL gets 16-17 km/l in the city. Any ideas on whats causing the ?

It seems like somethings off with your car, and the catalytic cleaning might have made it worse. Try switching to 5W30 oil and use a fuel system cleaner like Liqui Moly in a full tank, then drive it hard. Also, get your AC checked for low refrigerant o r clogs. A visit to a good EFI electrician might help too.
