Bad fuel mileage
I’m getting TERRIBLE fuel mileage, like a 5km drive will run me 20km worth of fuel. I don’t drive it hard, I let it warm up, and I keep it maintenanced. My car will run anywhere from 12.9-40.9L/100km when it should be from 7-9. For reference I have a 2023 VW Taos Highline AWD (~72—-km), and I’ve already taken it to VW to get looked at and they said they couldn’t find any problems. Some days the car will run perfectly and fuel little to no fuel but other days it will run horribly and guzzle fuel. As a comparison my 3/4 ton Duramax Diesel truck runs at about 16L/100km for average mileage. Just wondering if anyone else is having this problem??
Just to add here as an edit: this car has never had any issues with anything ever, never needed repair, just bad fuel economy. The lowest I’ve ever seen my mileage after 3 years of owning it new from the dealership was 7.2L/100km.
