I have noticed the last two months or so that I haven't quite been getting the same gas milage as I usually do. I figured perhaps the car needs a bit of a tune up, though I've owned it for 7 years and it's needed tune ups before and I never noticed a dip in fuel efficiency. When I mentioned this to Steve, he said he and Mike had been noticing this as well. They both have sizable commutes where losing a couple of miles per gallon starts to add up and become apparent. When Betty was visiting a few weeks ago, I asked her, and she said she had noticed it as well.

Is there something going on? Yesterday Steve emails me this.

I'm not quite sure that this is the answer, though it has been unseasonably warm the past month or two. I never noticed a difference before during the hottest summer months, and since that is notoriously the time of year when gas prices are the highest, I'm usually keeping a close eye on it all.

Anyone else notice a mile or two per gallon shaved off of their fuel efficiency?
