September is about the time the winter formula is produced. Longer engine warm up time doesn't help either. Colder temps also mean lower tire pressure. A lot of little things add up.Don't laugh but I swear.....in the last few months, my V8's have been sipping extra thirsty. It's like it's being used up at 33% more than it's normal rate....
I don't track mielage per tank but this is more seat of the pants observation in all 3 of the 'V8s....
Am I going crazy but has anyone noticed the same or has something with fuel ....
I don't know what you have, if they can display fuel trims on a scanner, it would be worth seeing how well the engines are running.
