Full tank?
Wondering if someone can enlighten me about this. When I first bought my kia Niro 2023 in Sept this year I was able to fill up the petrol tank to 507 miles max. Now, just a couple of months after, I'm only able to fill it up to 486 miles. Why have I lost these 20 miles? This morning after filling up the tank to the very top which again was 486 miles I went to a second petrol station just to see if I could top up some more. I was able to add a further £4.70. But then when I started the car it still read 486 miles. Doesn't seem right to me. Anyone else with this issue? I appreciate it.
The range estimate isn't super precise to begin with, and it can change based on driving style, weather, and even the fuel's blend. Adding a few quid after a full tank is normal, it's just topping off the vapor space. But the 20-mile drop in the displayed range is odd. Maybe check your tire pressure, underinflation can affect fuel economy and thus the range estimate.
