what is sad about this picture is that today i filled up my wifes X3 and it also took 19 gallons. it is about half the size of the LC with 50% better gas mileage at minimumOkay here's an interesting piece of information to add to this issue. I decided to let my tank run down past indicated empty and indicated zero range. I drove maybe another 20 to 25 miles but I didn't keep track of it exactly because I didn't notice exactly when the gauge went to zero.
But the point is I drove it for a while after empty and then just now I brimmed the tank until it's splashed out and put over 19 gallons in assuming I can trust a regulated/ inspected pump.
I usually pump in about 15 gallons if I'm down near empty so this extra reserve in the tank is significant. Also seem surprising that they rate the tank 17.9 but I got over a gallon more than that. I guess some is in the filler neck but still seems like a big discrepancy.
