As for most of the other factors; none of them are relevant to me (if anything, I bias my driving to get as much fuel economy as possible), religously check tire inflation, minimize a/c use, we have short rainy seasons, and the roads are neither hilly, windy, coarse, or other unusuals. The engine tune has been checked, thoroughly, by a dealer. I have no information on what you mean by "tire type"; mine are the original tires (bridgestone potenza I believe, which I have had balanced and rotated every 5,000 miles); if you have a specific suggestion on a tire type that could increase mpg, please provide. |

Something must be wrong with your vehicle then. How many rpm's are you turning at 60 mph - maybe your toque converter is not locking up. Are you using ethonol blended fuel - that will reduce mileage by about 5%. Tires are quite important. I would try about 34-36 psi if you are running lower. As for tires with reduced rolling resistance, one of the best is the Michelin energy (so named because of low rolling resistance). Just changing the tires won't do miracles, but could add as much as 2 mpg. Speaking of tires, it is possible that one or more of your tires is mildly defective, and this could increase rolling resistance. Another way to add a little mpg is to use synthetic oil - maybe up to 1 mpg on the highway, with the added benefit of slightly longer change intervals and more protection in the cold as synthetic flows better. It just doesn't seem right that you can't top 30 mpg. My Sienna with a V-6 and lots of wind drag gets about 26 mpg going 70. If I drop to 65 or slightly lower I can top 30. Once had a tailwind on a long trip and got nearly 30 mpg averaging about 73 mph. When I get up to 80 mph though, I am in the low 20's - just too much air to push. The worst I have ever measured was about 20.5 mpg going 80 mph into a strong headwind - lots of wind in SD. BTW - have you every checked the accuracy of your odometer? Maybe it is not ticking off the miles fast enough. The markers on the highway should be a good guide.

Replying to: phd86 (Feb 27, 2006 9:19 pm) 210delray #7926 - 05 LE - 26 mpg freeway 210delray #7432 - 04 LE - 26.9 mpg (supecedes msg #7926) I didn't know what your post numbers meant -- we're only up to #103 with my post here. And by saying 26.9 mpg supersedes the earlier post "26 mpg freeway," I took it you meant I reported 26.9 mpg in freeway driving. Now I get it: 26.9 was my overall average at the time. And that improved slightly to 27.3 mpg by 15,802 miles, when my son took the car. Sorry, I don't keep track of percentage of city vs. highway driving; I just note when the car was used on a long trip. Besides, my wife drove both Camrys most of the time when we were not on a trip, and she's not about to keep such records! However, now that I've begun using the '04 Camry for my daily commute, it will be interesting to see the kind of mileage I get. In my '98 Nissan Frontier, with pretty much the same routine day after day, I got 26 mpg time after time. We'll see how the '04 Camry fares under the same conditions -- I would expect better, but who knows? |

Replying to: phd86 (Feb 27, 2006 9:19 pm) The trip itself (LA to central VA): 30.3 mpg (3767 miles, 124.32 gallons, 10 consecutive tankfuls) mostly 2-lane roads, 3 people, full trunk, cold temps a good deal of the way, and high altitudes in NV, UT, and CO. Also stopping and touring in towns and national parks along the way. This is as good as it gets for real-world long-trip driving, at least in the winter on 2-lane roads. (This was in the '04 Camry 4-cyl 4A). I suppose coast-to-coast at a steady 65 mph on I-80 with two people and light luggage in the summertime would do better, no?

Replying to: dudleyr (Feb 28, 2006 12:38 pm) 2. Ethanol blended fuel is available and I have tried it at least 5 times (I also keep track of the brand of fuel). It has no effect. 3. I know about the low rolling resistance tires and have used them on my other car. On that car, also a camry, I should tell you there was no difference in mileage on the cheapo dunlops versus the $600 MXV4's. They are quieter tires IMHO and wear better. 4. Tried a couple oils. Mainly castrol. I change every 3,000 and since it's not cold here, I doubt I'd save enough gas money with synthetics to make it worthwhile. 5. Odometer - I've not checked it specifically. Doubt that three camry's (two 2004, and one 2005) would all have errant odometers. I'll do that on both my cars and report back soon. Have you checked yours? 6. Can't respond to Sienna V6 - different animal. |

Replying to: 210delray (Feb 28, 2006 6:58 pm) I think what you are trying to say you would get some ungodly much greater mileage than 30 mpg, if you did similar driving that I do (no luggage constant 65 mph). My other thoughts are: a) that this thing about weight probably makes little difference, b) you didn't do as much driving in city as you think you did, perhaps a couple hundred miles, but not a whole lot; and c) your definition of winter means you probably didn't use the A/C, but weren't really driving in mountains with snow and ice. Just some cool temperatures in southern parts of those states. I could be all wrong on that, but those are my thoughts. BTW, do you have a favorite brand of gasoline, or recall the dominant brand on this trip of yours?

Replying to: phd86 (Feb 28, 2006 8:50 pm) On my cross-country trip: a) I don't see how the extra weight could not have bogged down the mileage: about 470 pounds for the 3 people, plus the trunk was fully loaded (including heavy items like a nightstand and books), as was the left rear seat (upholstered dining-room type chair, small end table, and more books). I would not be surprised if we were close to the max payload of the car (900 pounds). b) We accumulated 90 miles in Arches Nat'l Park alone (admittedly not a city, but all speed limits there were 45 mph or less, with lots of starts and stops for overlooks and short walks). We also spent lots of time touring small towns for their architectural glories, including in CO alone the towns of Delta, Montrose, Gunnison, Salida, Canon City, and Pueblo. So a LOT more than 200 miles was accumulated in towns. c) We saw temps as low as +10 degrees (F) in eastern NV, +15 in eastern Utah, +14 on Monarch Pass, CO, and closer to home, +24 on Cheat Mountain, WV. There most definitely was snow and ice present, generally not ON the road, because of excellent salting and snow plowing, in all of the higher altitude areas of NV, UT, CO, and WV, as well as western KS. We first traveled north out of the LA basin and then basically east along US routes 6, 50, 56, and farther on, I-70, SR 32 (Ohio), and US 250. Only on one day did temps exceed 60 degrees. The most common brand of gas we used happened to be Shell, using the lowest grade of 87 (except midgrade 87 or 88 in the high-altitude areas of NV, UT, and CO).

| After 105,000 miles, the overall average in 28.3 MPG, adjusted for the 3.2% odo error (low). Highest observed over at least 1,000 miles is 32 MPG, running at a steady 65-70 MPH with non-ethanol gas and no A/C. The mileage is very sensitive to tire pressure; I keep it at 32 LB. A/C reduces mileage by about 1.5 MPG. Lowest observed is winter driving where it drops to about 22 MPG. | |

I'm getting pretty consistant 27 MPG. 80% city 20 % highway. Actually maybe even more city then 80%. I keep the wheels full of air. I just started running Mobil 1 synthetic not sure if it has upped the mileage any, it may have. Also it's an automatic with 77,000 miles in Florida Ac running all of its life. |
