#174 of 221 Re: Gas Mileage Test [biker4] by fedlawman Jul 11, 2007 (5:39 am)
Replying to: biker4 (Jul 11, 2007 5:21 am) It was a good effort, but I saw a few issues with that test you linked. Here are a couple off the top of my head:   Test 1 and Test 3 were both done at 55 MPH, but one had cooler temps and a headwind, and the other had warmer temps and a tailwind.   Test 1 and Test 2 appear to be from the same stretch of road (on the same day even), but Test 2 was done at a slower road speed.   I agree with your thinking though. The only way to compare 87 octane and 91 octane economy is to do it with the same car, on the same road, under the same environmental conditions.   It's meaningless to try and compare a TSX in NJ that gets 41 MPG on 87 octane and a TSX in San Francisco that gets 22 MPG on 91 octane.

Replying to: nj2pa2nc (Jul 10, 2007 5:24 am) For shame. "I can't drive 55" is NOT a Van Halen song, it's a solo by that sham of a lead singer they hired after David Lee Roth left the band. NEVER confuse solo Sammy Hagar with Van Halen. Further, with him at the helm, the band was "Van Hagar" and only a shell of its former incarnation.

#177 of 221 Reg -vs- Pre fuel by mrgold35 Jul 30, 2007 (12:35 pm)
If you drive the TSX well below its performance envelope (around town, cruise control on level highway, light loads in the car, etc) all you need is regular fuel. You will not see much of a difference in mpgs.   If you drive your car closer to its performance envelope (sprints to redline, very spirited driving on mountain switchbacks, full load in the car, etc), then you need 89 or 91 octane to squeeze the max performance from the k24 engine.   I do most of my traveling in New Mexico, Arizona, and Colorado at altitudes from 1100 feet to +11,000 feet. I-70 westbound mountain pass around Clear Creek, west of Denver, is at 11,013 feet. Put 87 octane in your TSX and hit that stretch of road. Run your mileage test in this environment and then you will see a “statistically significant” change in your mpgs/power/performance.   Choose the fuel that best fits for your driving environment/habits.

Replying to: mrgold35 (Jul 30, 2007 12:35 pm) thanks-that is what I have been trying to say-regular gas works for me but maybe not for others-

#182 of 221 Re: 4500 Mile Update [thomcin] by kts62 Aug 21, 2007 (5:37 pm)
Replying to: thomcin (Jul 10, 2007 7:51 am) This MAtches my very slight experience as I only picked up my TSX a couple days ago...   Mine is an 2008 and just one tank of gas. I'm getting 34 peak highway and 31 +/- on commute (mix Hwy, Local)   Incidentally, the 2008 brochure says 91 Octane REQUIRED and the manual simply says specifies "91 Octane" without any recommended or required language... I followed up with both GM and Service Mgr at the selling dealer and then hadn't noticed the change as yet and admitted it was change to te documentaiton. Then at delivery, I found out that they filled it with 87 octane ! Go Figure !!!
