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: thomcin (Jul 10, 2007 7:51 am) 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 !!! |

Hi, I bought my new 2007 TSX 2 months back and am getting only 18 MPG for about 1500 miles of mainly city driving (75% city/25% highway). I use 89 Octane fuel. It is summer in DC and so the AC is working overtime but, this appears really low. Anyone else with the same experience? Should I call the dealer? Thanks,

Replying to: sm1 (Aug 27, 2007 4:30 pm) The TSX really hates city driving. Stop/go traffic in an I-4 pulling +3500 lbs from a dead stop every 300-600 feet(car's mass, gasoline weight, passenger(s), junk in the trunk, A/C, etc). Maybe a longer route with less lights might be better compared to a shorter route with more lights? Take a drive on the hwy with the cruise set between 70-75 mph, you will see around 30-34 mpgs on average.

Replying to: mrgold35 (Aug 28, 2007 9:58 am) I use my TSX for commuter driving which here in greater Boston means congested Highway miles with Urban Stop-n-Go at both ends (80 Hwy/20 City). I am averaging 31.3 - 32.5 for my first few tanks and I can't tell the difference between the 87 Octane the dealer filled it with and the Shell V-Power 93 I have now filled it with 3 Times. |
