#184 of 221 Low Mileage/Should I get my car checked? by sm1 Aug 27, 2007 (4:30 pm)
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, Replies to this message: mrgold35 (Aug 28, 2007 9:58 am) kts62 (Sep 03, 2007 6:09 am)

Replying to: sm1 (Aug 27, 2007 4:30 pm) In heavy city stop and go traffic, 17-20 mpg sounds about normal for the TSX. You would get pretty much the same mpgs with 87 or +91 octane fuel.   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'm not sure I'd get my car checked, but I think better MPG is available to you. Mrgold35's reply sounds right on target. The TSX has good driving feel in part because its solid - which inevitably leads to at least a bit heavier. Accelerating from a stop takes much more gas than cruising at constant speed.   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.
#187 of 221 8000 mile update by thomcin Sep 05, 2007 (12:42 pm)
Total combined mileage to date (4 months) 8,000 miles 30.0 mpg   Total mpg highway 32 Total mpg city 26   Have used all three grades of gas with premium getting the best mileage by about 5%. What little you save getting another grade of gas (87 or 89) tends to be eaten up in less mpg using the lower grades.
#188 of 221 Best Mileage to date by mrgold35 Sep 05, 2007 (2:42 pm)
I took a weekend trip during Labor Day from Albuquerque to Bison Ranch in Northern Arizona. On the way back from Arizona, I average 42.5 mpg at 60 mph for 40 miles until I reached the interstate. I watched my mpgs decline on the interstate for 240 miles to an average of 35.3 mpg with the cruise set to 80 mph (used 91 octane, elevation between 5000-7700 feet, outside temp between 75-90 degrees, no wind, 3 passengers and lots of junk in the trunk, recent oil change of Mobil 1 5w-30 and cleaned my K/N filter before trip).

#192 of 221 Is frequent shifting the automatic in/out of neutral bad? by obladida1 Oct 18, 2007 (5:09 pm)
First off: You guys are my heros! I WISH I could get that kinda mileage out of my '07 auto/nav. I live in the L.A. Valley and I commute to the beach, so I have a big twisty hill to get over twice a day. My average for almost 4K miles is 26.9.   When I am going downhill, I sometimes drop the tranny to neutral and coast much of the way. Is it bad for the automatic transmission to be popped in/out of neutral and/or left in neutral for extended periods?
