I love my michelins on my 06 SE, yes, it is a little stiff, especially when they are going over bumps... I like the stiffer ride though. I do think having them aired with a little higher psi is better... and I can tell the difference too. I love the mileage, I am not sure what I get, I have never really checked, but I can drive 7 out of the 7 days and drive about 1 hour or so total each day and use a tank. So if I fill up monday, I can typically fill back up that next monday or tuesday, perhaps even on that wednesday. I never have taken the time to check my actual mileage... seems normal, does excellent on highway, which makes all the difference.
 
Another things with the michelins, they wear very well!!! They literally still look like new, the tred and side walls look great, although I keep them shined all the time.
Keep them rotated and they last!! I have only 32k on them.

Amen, bro...........
 
The Mich MXM4 pilot a/s 215/50-17 tars on my 6M measure 6/32 remaining (that's at 49k). Yes, indeed..................they aren't the best rain tars, but the wear index is something to write home about..............
 
best, ez....

Anyone ever test to see if premium improves mileage? I know it's not recommended but I'm curious if it's a fact. I would do it, but I'm still trying to baseline by 08 4 cylinder on normal gas. So far it looks like I"m right in the middle of the range- I'll report actual numbers at my second fillup.

My understanding (not based on personal tests) is as follows:
 
1. If you put premium gas into a car that calls for regular, you're wasting your money because it won't improve fuel efficiency or performance.
 
2. If you put regular gas into a car that calls for premium, you're not actually saving money because your gas mileage will be worse (as will
your performance).

Not necessarily true. Instead, it will likely reduce peak power. Our 2000 Odyssey ran with the same mileage on regular as it did on premium (it recommended 91 octane).

From what I understand, elevation can be a factor in the utility of high octane gas. At high elevations, I've been told that there simply isn't enough oxygen in the combustion air to take advantage of the higher octane levels. I live at 6500 feet and get to run my I4 08 Accord on 85 octane gas (rather than 87). I understand that this octane is not available at lower elevations.

I think the cut off is 3,000 ft. I get 85 in western SD and 87 in the east. Some of my best mpg has been with 85. Remember that octane is the resistance to combustion. Higher octane means less energy. Of course higher octane allows for advanced timing which helps with hp and efficiency.
 
Off topic, but back in the old days I had a stick shift Scirocco (1980) with breaker point ignition. You have to manually set the timing when you change the points. I advanced the **** out of it once to see the effects. I had to be really careful not to accelerate too fast because of pinging, but my mpg went from about 37 to about 47. 10 gallon tank took me from D.C. to Rochester NY and I was not too much below the halfway mark. I backed it off and found a nice compromise where I got about 42 mpg and the engine almost never pinged. Wasn't going too fast back then as the national speed limit was 55.
 
Back to today and my much larger, 1,100 lb heavier, 90 more hp Accord gets about the same mpg. It is constantly adjusting timing to optimum levels for efficiency (unlike the fixed timing of the past) and that makes a huge difference.

Move away from NY. Seriously though there isn't enough information about your driving style for anybody to guess. Also, mileage should be starting to improve within the next couple of months as "winter-blend" gasoline starts to be phased out and they start to phase "summer-blend" back in. "Winter-blend" really hurts mileage on most cars. Have you had to use to defrost a lot this winter, I know that I have, living in MN? The defrost for this generation turns the A/C on automatically. There is a hack to override that function in this discussion. Search for A/C Hack. That could be part of what is bring your mileage down.
 
Somebody who has a little more knowledge on why "winter-blend" hurts mileage I'd love to hear it. I tried to find a link that I looked at a long time ago, but was unsuccessful.

Speed and fuel economy by bug4

Interesting article on speed and how it affects fuel economy. For the average sedan, every 10mph over 60mph adds 54 cents a gallon. . . .
