Not sure. To be honest, it's old, and since I have been working from home, I don't drive it nearly as often as I did when I was commuting to work (pre-Covid). Back then, it got better gas mileage, probably closer to 21 to 23 mpg on my commute (45 minutes in DFW). Now, it sits a lot, and the last time I checked the mileage, it was around 14 to 16 or so (that's per the dashboard monitor, not with me calculating it via a spreadsheet or other manual way). These days my trips are less than five miles around town, and I rarely take it past that, so it is now doing a lot of stop-and-go driving where before the majority of my work commute was on George Bush Tollway, so I was doing 75 mph most of the trip. That is probably the reason for the bad gas mileage now. I imagine the AWD would make the gas mileage worse than a Pilot. How old is the Pilot?
