Replying to: wise1 (Jun 24, 2007 5:21 pm) 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.

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.... |

Replying to: seekingperfect (Mar 31, 2008 3:50 pm) 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).

Replying to: davidd3 (Mar 31, 2008 6:06 pm) 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). |

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. |

6.000 miles currently and getting avg of 17 mpg local city dirve and 24 mpg highway. Little use of AC. NY area driving. Any suggestions for improving mpg? |

Replying to: garrick (Apr 02, 2008 5:21 am) 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.

Interesting article on speed and how it affects fuel economy. For the average sedan, every 10mph over 60mph adds 54 cents a gallon. . . . http://finance.yahoo.com/family-home/article/104752/Slow-Down-a-Lttle-Save-a-Lot- -of-Gas |
