Hi I just bought a 2013 rx350 ultra premium from a Lexus dealership. It's my third day with the car and I noticed it said I'm using 15.6L/100km which seems terrible.

The car is rated for
City 11.8 L/100km
Highway 8.3 L/100km
Combined 10.2 L/100km

I know it's a few years old and numbers tend to be a little higher than that. I was expecting 12-13 city but 15.6 is alarming.

The car was inspected and everything at the dealership and runs fine. So I don't know if this is normal or not.

The car currently has 98000km, always been serviced regularly at dealerships according to the Car proof report
