Average MPG = 26.18 very good for an average. I think I average around 26 also. Highway I can do 32-33mpg.

Average Cost PG = $2.06 I'm paying $2.79 range.

 

i feel ya. i definitely don't miss california gas prices. i'm averaging about $2.25, but that's still pretty expensive for houston standards.

anyway, i'm looking at about 30mpg with about 90% highway driving. that goes down to about 28 when it's about 75% highway. with my current commute/schedule, i'm getting 31mpg. i'll post my mpg for the same exact commute with the injen cai. hope there's not too much difference.

 

Half fills are easy enough to accomodate. On the spreadsheet I used for years for my Civic, I just noted whether it was a fill or not (wrote this on the receipt at the time of fill). If the current fill was only a partial fill, the spreadsheet would just roll this amount forward until a complete fill, and do the fuel economy calculation at that time. So, in the example below, the 8.46 L/100km (27.80 MPG) result shown in row 21 is a result of using 27.83 + 35.43 = 63.26 litres to go 4875 - 4127 = 748 km. Make sense?



I don't have any results from my TSX yet, as I'm still on the first tank of fuel from the dealer!

P.S. Want to do quick and easy conversion back and forth between L/100km and MPG? Try the Google calculator:

don't alot of people average 400mi per tank?

 

Well, I finally put my fist tank of fuel into it! Following the break-in procedures described at the start of this thread, I got 24.1 MPG (9.8 L/100km). This was for 50% city driving, 50% mountain highway driving.

I expect this to improve as the engine loosens up, and when I stop the weird break-in driving (constantly varying the speed, running up the RPM, etc.) We'll see!

 

I used to drive on highway alot.. probably 20% city, 80% highway. In that case, I always had 32~35MPG

Now that I am taking summer school in a local college, I drive 90% city, 10% highway and get 25~26MPG. This sucks BUT compared to other cars, TSX gives out great MPG!!

 

90% City and still 25~26MPG?

That's great. I get 25~27MPG and I do 70 highway/30 city.

 

Yesterday I broke my personal best for amount of mileage out of 1 tank of gas. I hit 482.3 miles out of 1 tank of gas. I should have held out for 500 even but the light was already on and The trip meter read --- miles to go. Averaged 29.6 mpg

 

Keep it up.

 

Through 3 tanks in my 2005 AT, I am averaging 23.7 MPG. Unfortunately, my car is used almost entirely for commuting thus far, so I'm at about 90% city/stop and go and 10% open highway.

I just realized this week that I can turn off the AC and still have the rest of the system on auto, so I'll have the AC off for at least my morning drive. Between that and the engine breaking in, I'm hoping to get the average up to 25 MPG.

 

orginal tank of gas, provided by the dealer, gave me the best mileage so far...~530km's until the warning light pops up.

as i'm nearing the end of my second tank of gas, first fill-up from myself, i may be struggling to get ~500km's until the warning light.

i drive close 95-98% city...

 

How's this??? I always use premium and commute about 70 miles round trip daily to work, which is mostly highway driving. I guess I'd say I also do a reasonable amount of around town driving to run errands and visit friends. But overall, a lot of 70mph interstate.

ok, my pics aren't working

 

trying this again

yeah, ok... read the FAQs if you want to post pics... ha... anyway... sorry it's so small, i'm not really sure how to fix that...

 

Wow, those are some detailed chart. Good job...the gas prices are relatively cheap for LA.

 

donnie214,
Nice. I see where it started at around 25MPG and is trending more near 29MPG after 20K miles. What kind of driving do you do on average? %city/%hwy? What kind of oil do you use?

 

Good job Donnie!

 

I noticed the trend too. I'm pretty sure I did a lot of extra around town driving during my first month or so just to cruise in my new "ride" if you know what I mean; so the mileage during that time would naturally be lowered. But supposedly there is lower fuel mileage associated with break-in, so that may have factored in some also. Another thing to factor in is that after I broke it in, I probably floored it at least once a day during the week, but now I usually only do that when I pass someone, which may be only twice a week. I guess I've calmed down a little. I still drive "sporty" but I am fuel conscious; I usually don't go past 4000-4500 rpm when I accelerate.

One of the most curious trends that I noticed is what seems like a seasonal trend. If you noticed, during the cooler months my fuel mileage got better. For those of you from up north, winter months in south Louisiana are more mild than anything (probably average between 55-65 degrees), but summers are rather extreme on the heat end of things (over 90 degrees almost every day). From what I've read in my owners manual and other places, temperatures above 90 degrees and below something around 50 degrees (I can't really remember) are considered to be "extreme temperatures." Supposedly fuel mileage can suffer a lot in extreme temps; and it looks like that might be happening in the graphs.

I haven't consistently used the same brand oil, but I changed it at 7500, 11000, 15000, and 20,000. I changed my oil filter every other oil change (as specified in the owners' manual) which was at 11000 and 20,000. I thought I might go with the "regular maintenance schedule" listed in the manual, but looking at my oil at 7500, I decided to start following the sever maintenance schedule. I haven't used any synthetics, but I've always used brand name stuff. I think I've used castrol, halvoline, and pennsoil. I can't really say that one or the other has made a difference.

As far as my highway/city driving goes, I would say that I drive a lot on the highway. I really don't feel like I do much in town driving; although, I do probably make one or short in town trips a day, but even these are usually only 5 to 10 miles round trip. My highway driving consists of my 5 day a week commute from home to work. The commute is about 35 miles one way. There are about 10 stops the whole way. Around 20 of the miles are spent travelling 70 mph, and another 7 to 9 are spent going about 63 mph. The rest is about 30-40 mph stuff. Even at 30 mph, as long as I'm not accelerating, I put it in 6th gear. Every now and then I'll make a trip out of town on the weekend that's about 140 miles round trip.

One of the biggest impacts on my mileage seems to be the length of my trips. If I get in my car and drive for 5 minutes, shut it down for an hour, then drive for 5 more minutes, a few times a day, it seems like my mileage really takes a hit. But if I can go around town and only stop for a minute, even if it's around town, the mileage doesn't seem to get as bad. So I really try to run my errands all at once, rather than spreading them out during the day. I've read that when the engine is cold, fuel mileage really sucks, so by keeping it warm it should help; plus I guess the A/C doesn't have to work as hard to cool the car down if it doesn't sit in the sun very long. I'm sure some of that could result in less in town miles as well, so that can be hard to rule out.

Anyway... hope that helps...

 

Oh yeah, and if you noticed that the first tank of gas had over 30 mpg, that was mainly because I purchased the car out of state. I drove over 350 miles from the dealership to my home.

 

thanks for your very detailed response. 29MPG is pretty darn good for an average. Your summers are not only hot but humid too. The humidity probably affects your mileage as well.

 

My TSX


Just for fun... My Vette

Looks like I need to update my chart

 

Forgot to add acurazine.com to my hotlinkable sites list. Should be showing up fine now.

 

nope, still don't see them.

 

Is it still red-x'ing? I just cleared my cached, and refreshed the page and they came up fine. I'm stumped, and I don't see anyway to delete my post. Sorry guys, I really am not a noob to this stuff!

Is this forum hosted on any other URLS other than acurazine.com?

 

As you can see, my break-in period didn't help my MPG much

 

mine since last reset,

 

THe speed really matters....
My average daily commute is 72 miles highway (@ 80-90mph) and 8 miles city (@30mph or so, depending on traffic). And my trip computer is showing 23.5mpg now and about 22.0-22.7 when I am on the highway. I am only on my second tank though (got a 1 year old car).

 

Just to post a little update... i found an alternate route to work (I commute 35 miles one way) that's giving me about another 2-3 mpg. My new route is roughly the same distance, but has a lower speed limit. My overall travel time is almost the same as before because there are fewer stops and less in-town driving. It might take me another 3 minutes to get to work now (never really used a stopwatch or anything)... 3 minutes isn't a big deal to me.

I do about a third of the 70mph interstate driving that I used to and now i'm doing a lot more 55 mph back road driving. It's really nice, b/c there is usually a lot less traffic on the roads too. I haven't updated my fuel mileage charts yet, but I'm getting around 31 mpg now, where I used to get about 28-29 mpg. I think the best I've had with my new route was like 31.5 mpg so far.

However, these results could possibly be a little higher, b/c i'm only commuting 4 days a week now (I used to commute 5 days a week). So that gives me one extra day of non-highway travel. Even though I don't do a lot of around town driving on the day i'm not commuting anymore, I can imagine this making at least a 1/2 to 1 mpg difference, so if I did start commuting 5 days a week again, maybe I'd start to see some 32 mpg plus figures. Hopefully I'll never find out! I really like working from home that day.

Something else I did about a month before I changed my route was to switch my A/C onto the recirculate mode. I figure the A/C doesn't have to work as hard if it's recirculating air that has already been mostly cooled instead of sucking in 90+ degree air from outside the car. Plus I don't have to smell everyones shitty exhaust fumes coming from their 1990 Chevy Cavaliers that never had their oil changed.

I also cranked up the air pressure in my tires to like 36 psi for the fronts but I left the rears at 30. -- The rears, IMO, don't need any extra pressure b/c of the reduced weight on them... even with the 36/30 front/rear setup, my front tires are still squatted down a lot more than the rear tires. As far as results go (the A/C and the tire pressure), this was really tuff to tell. I mean, hell... we're talking about maybe 1 mpg.. a change of weather or a gas pump that decides to shut off a little later than normal can throw you off almost that much. With all that said, yeah, it "seemed like" the mpg got a little better. I'd guess something like a 1/2 mpg difference, but like I said, it's pretty hard to tell with all of the other factors.

Anyway, when I get a chance, I'll update and post my MPG chart again. Hope ya'll can use my "data."

 

Great transportation planification Donnie.

 

I can't find this screen on my 2006.
Is it an '04-'05 option only since the '06's have the MID?

 

ive only had the car for about 5 days but right now the average mpg is 32.5 mpg

 

 

Such a mileage so early is GREAT. Just make sure you don't run the engine too smoothly during the breakin.

 

Yes, Trip Computer option is in the '04 - '05 Navi.

 

An update:

Last 5 fill ups were:
2/16/06 - 28.6mpg
2/19/06 - 29.1mpg
2/24/06 - 31.4mpg
3/12/06 - 25.6mpg
4/08/06 - 25.8mpg

Overall, since I've owned the car:

Total Fuel Purchased: 441.69gal
Avg. Fuel Purchased: 11.62gal
Avg. Fuel Efficiency: 27.2mpg

 

Well, that sucks. I wish they kept that feature in the '06.
It's easier to read than the MID.

 

I've been getting a consistent 22 mpg, driving either stop and go or 8.5 miles one way to work, mostly on the Interstate. I could probably get better than that, but I tend to take the term "acceleration lane" literally. I have an automatic and run the a/c constantly (living in Florida), and I use premium gas.

I haven't had the opportunity to take any kind of trip as of yet, so we'll see how it does then. I tend to cruise at about 80-85, but the FHP has been heavily patrolling a major interchange I pas through every day so I don't go above 70. I figure that if I'm not the fastest car on the road my chances of getting nabbed should be reduced.

I should add that I compute the mpg manually rather than rely on the on-board computer. In any event, I'm satisfied. The car is really quick and fun to drive and I'm happy I got it...
