They probably let the air out of your tires if you were running high, or even recommended pressure.

Every mechanic would let air out of my tires even when I was running the factory recommended 38/38 in my I1... when I started running max sidewall, they would come running saying "whew, I fixed your car, it was about to blow up" and let it down to 30/30 or 32/32.

I keep my tires at 44psi and when Honda did my first oil change I was very surprised that they left them at 44. I did pull out my 30% radiator block before I brought it in.

no, the tires have the same pressure b4 and after ... i was thinking that the blockiness of the rears brought forward could perhaps equal more friction and hence lower mpg ... it's no biggie either way

I guess I never answered the original ? My mileage increased after the first oil change and tire rotation, not decreased. I read in this forum to expect that and it did for me anyway.

MPG increases from an oil change when you leave it in too long. The oil gets too dirty and stop lubricating like it use to. I havent seen a mpg change in cvt fluid change, just the way it performs.

In my case this happens as I have -3 degrees of camber. The front wheels wear slightly unevenly so for the first thousand or so the mpg is a tad lower, then as they wear it comes back.

Not suprised.
Regardless of alignment, after a while, wear patterns develop.
Cobb is correct, camber is effecting it. Each wheel will be slightly different.
Rotating evens tire wear.
Give em 1000k mi, and tell us what MPG is.
Suspect that after a little wear, MPG will be back!!

didn't even take that long ... with about 500 miles since the rotation the mpg is back to (and above) where it was before
