Replying to: flicmod (Jun 03, 2005 6:18 am) Thanks for the info on running the tank empty. Like I said, I didn't know if there was a risk by running the tank low. I guess it is just fine. I appreciate the post.

Replying to: rko2 (Jun 03, 2005 6:35 am) I was more interested in throwing out maybe a urban legend out for discussion...and perhaps dispell an ingrained thought perpetuated by the oil marketeers (make sure to READ the USAToday article which I linked to)   Where I was at is that over a course of a year...the $2 a tank savings would be generate $125-$150+ over 12 months.   $150 savings could go towards other toys.   And if the performance issue is reducing the measurable horsepower from 200 to 190...not sure if the performance would be noticable.   I still question whether MPG truly improve by 2 by switching grades. Maybe I am wrong.   Where I am personally. I use premium and don't anticipate to go down to a lower grade. Here in Southern California...premium is $0.20 to $0.25 more. Of course...I use a gas rebate card. 5% cash back with Discover. 3% with my Chase Visa.   So once again...the question to consider is the urban legend truth?
#13 of 221 TSX mileage by manavi Jun 03, 2005 (2:59 pm)
I'm getting about 26.5 MPG in my 2005 TSX. I'm only on the highway about 20% of the time.   Regarding the premium gas versus regular gas:   We have one TSX driver who already experimented with using regular gas and stated his mileage was reduced from 420 miles on a tank to 320 miles on a tank. That equates to roughly a 30% increase in mileage by using premium gas in the TSX.   It seems like one would actually spend more money by using regular gas in the TSX. Does anyone have any data showing that using regular gas in the TSX will save you money?

We seriously considered an 04 TSX, but ended up with an A4 for the more comfortable seating. Glad we did when looking at the mileage figures posted here.   We use 89 octain in 04 A4 1.8T that calls for 91. Consistently beat EPAs handily (27-29 around town; 33-35 highway).   On the other hand, I have a 92 Civic Si that specifies 87 octane, but use I 89 because with 169,000 it knocks w lower octane.   I cannot detect performance difference in either car as describe above.   However we loaned our A4 & it came back with a full tank & ran poorly until we topped if off with 91 octane. I suspect that it was filled with a low grade low octane gas. Replies to this message: mreed (Jun 06, 2005 5:59 am)

15947 miles / 549.946 gallons (almost exclusively 93 octane) = 28.997 mpg.   Best tank: 34.442 Worst tank: 21.205   I
#16 of 221 Phenomenal Highway Mileage! by ronabi Jun 05, 2005 (10:49 pm)
With almost 5000 miles on my 05 TSX with auto, my overall average is 27.7 in mixed driving. My lowest was my second fill-up at 24.5 in 90% around town driving. Highest was my last fill-up at 37.8 in nearly 100% highway driving at an average speed of 70 mph. The second highest was 34.8 a week earlier in around 95%+ highway driving with highway speed averaging 70 mph.   Mileage has been increasing as time passes and the miles add up. I was ecstatic at the 34.8 figure and certainly never expected the 37.8 result. I'm curious if that will ever happen again. Fill-ups after mostly highway mileage have always been 30 or better, usually between 32 & 34 in recent weeks.   These calculations assume that the pump cuts off at the same point on all fill-ups, which is probably not so, but averaging over several tanks should correct for that. I am more than happy to buy premium fuel (mostly Exxon 91 octane plus a couple of tanks of 93 octane) when it results in mileage like this!

Replying to: 204meca (Jun 03, 2005 9:44 pm) That's awesome that you are saving some cash at the pump. You'll need it to make up for the 50% increase in expected repairs, and $2700 increase in depreciation vs. a TSX.   Enjoy!   (Figures quoted from Edmund's TCO for both cars)
#18 of 221 Mileage by stillageek Jun 06, 2005 (6:12 am)
I just finished a 550 mile round trip with 90% highway at speeds between 70-85 MPH the entire way. I averaged 32 MPG on the first leg and 33.2 on the return trip. Not bad at all. I am very pleased at the handling and ride of the TSX on the highway. The low amount of wind and road noise (compared to my last car Toyota Matrix XRS 6 speed) was also nice. Of course when I compare my mileage to my wifes car, 2004 Toyota Prius (which has averaged over 52 MPG since we got it) it doesn't seem so great. I have a 2005 Auto TSX and use only 93 Octane. What's with the 50% increase in expected repairs you are referring to? With a 4 year/50K warranty I will never need a repair while I drive it. Replies to this message: flicmod (Jun 06, 2005 10:53 am)

Replying to: stillageek (Jun 06, 2005 6:12 am) I think you mistaked his post. The 50% repair rating is comparing the A4 to the TSX. I believe he was referring to the poster that said he was getting better gas mileage with his A4 (since he decided to purchase that instead of a TSX). With 50% more repairs done to the A4 than the TSX, that extra gas money goes to the repairs. I believe he was harrassing our Audi fan
#20 of 221 harrassing our Audi fan by 204meca Jun 08, 2005 (9:27 pm)
flicmod, I agree that I was the one "harassed - no offense taken! I realize that earlier A4s have a checkered repair record, especially compared to the stellar record Acura/Honda. I really liked the TSX and am a long time Honda fine owning about half a dozen Civic variants the past 20 years My current daily driver is an 92 Civic Si with 170,000 miles! But my wife was simply stuck on the A4 - her fussy back found the seats unbeatable. I was dubious due to its repair reputation, but am still loving it after 20,000 trouble free miles.   Regarding A4 problems; most of the problems are atributable to the window regulators and the bum coil packs in the 02-03 models. Word is that Audi has those corrected in the 04 model and that they have extended warranty on those parts. Maybe I can make up some of the projected repair costs by the totally free maintenance that Audi provides for the 1st 4 yrs / 50, 000 miles.
