Hi everyone, I drive a 2005 MDX Touring with about 220K on it. Now that it is getting warm outside and have been running the a/c more, still not constantly, my MPG have dropped from a low 18 mpg to (the lowest) 9mpg! I don’t drive the vehicle hard, try to keep the a/c off whenever possible because of this issue, but I’ve had 3 Acura’s and 2 Honda’s and even the one 4 cylinder I had didn’t lose that much mpg when running the air full blast. What gives? Thanks!
