I've been noticing a drop in my mileage on my 2001-9-5 Aero as well. I've got 56-k on it, and recently had to have the plugs replaced because they were "fuel fouled" or so the dealer told me. Except for occassionally using 89 octane, I've always bit the price bullet and put it 92/93 octane. I check the tires every 4-6 weeks. The car seems to run fine. Any filters or other simple mechanicals we should check that might make a difference?
