Replying to: dudleyr (Jul 26, 2008 1:54 pm) I'm not sure who dudleyr is talking about; I didn't say the "data" here are irrelevant, I said that the information here is not "data". It is relevant to talk about, because what is reported here is subject to biases due to incomplete refill which are enlarged when gas volumes are low, discontinuous measurements, selective reporting (i.e., only higher calculated mpg's), lack of ability to authenticate, and various other sources of bias towards reporting of high mpg's.. The other thing that seems to be talked about, alot, is the feeling that a camry a) routinely achieves 30 mpg; and b) a camry is capable of achieving extraordinary efficiencies of 35+ mpg. I respectully submit that: (a) does not happen - on a routine basis; and that (b) has never, ever happened, anywhere, by any 2002-2008 camry in existence (with an automatic transmission). 26-28 mpg is what a camry gets, and that's it.

Replying to: troylikesbikes (Jul 25, 2008 12:13 pm) When the light came on in both my 2005 auto and my current 2007 manual, it takes approximately 15.5 gallons to fill the tank. So there is certainly more than 3.0 gallons in the tank when the gauge is showing 1/4 full." The operative word being "approximately": You probably didn't completely top off the tank. I get 16 gallons in when the light first comes on, and have done this dozens of times in my car, and several times, in other camrys. It is 2.5 gallons left when the light first comes on, almost right on the money.

Replying to: phd86 (Jul 28, 2008 7:41 pm) Talking about data quality and bias is a completely reasonable topic. For some reason, you focus on issues which you have decided only give artificially HIGH results. What about all the reasons included in this data which give artificially LOW results? Remember, bias exists in both directions, and a random distribution of bias means you still end up at the same answer. Lets start with the basics, dirty air filters, low tire pressures, a hole in someone's gas tank, people who drive their automatic with 2 feet, dragging emergency brakes or poorly functioing regular brake system, improperly functioning transmission ( common in more modern Camrys ) general warranty issues which go unfixed and affect efficiency, wheel bearings, CV boot issues, etc etc. So there are as many reasons, some might venture MORE, for why a normal Camry reported mileage should be LESS than it is...and I'm sure we have some of those issues reported here, demonstrated by people who took their car in and demanded it be "fixed" by the dealer when it doesn't give them the results they expect. And my 2005 2AZ-FE auto tranny Camry regularly returned 33 mpg, check out post #636 for the odometer readings, mileage, gallons, wind, weather and load. Not exceptional at all, and verified by the data here in the forum, as well as the EPA. |

It is 2.5 gallons left when the light first comes on, almost right on the money. Why do you assume something is wrong? It sounds like you are agreeing with me. Your numbers and mine sounds like it is perfectly within reason for 2 different Camrys. And of COURSE when the gauge is on 1/4 of a tank I have more than 3 gallons, I know this because my light comes on well below the 1/4 of a tank mark, and it takes some driving, some more driving, and then some more driving to get it there, and I certainly wasn't using air as fuel during the time and miles it took to get from the 1/4 tank mark to the light coming on. |

"The other thing that seems to be talked about, alot, is the feeling that a camry a) routinely achieves 30 mpg; and b) a camry is capable of achieving extraordinary efficiencies of 35+ mpg. I respectully submit that: (a) does not happen - on a routine basis; and that (b) has never, ever happened, anywhere, by any 2002-2008 camry in existence (with an automatic transmission). " We really need an icon with a car rolling its eyes. So people that get 35+ mpg are lying? At least the bar has been raised at one time it was "impossible" for any Camry to get 30 mpg on the highway.  I wonder how many pure highway (not even 5 miles of city) tanks it takes a person to reach a conclusion about everybody elses Camrys?  phd86 - How is the scangauge install going? Let us know how it helps. |

>> The other thing that seems to be talked about, alot, is the feeling that a camry a) routinely achieves 30 mpg; and b) a camry is capable of achieving extraordinary efficiencies of 35+ mpg. > a) If the speed is between 40 and 75 mph, no net elevation gain, light winds, mild to warm temps, and few brake applications- it is trivially easy to get 30+ MPG on a late model 4 cylinder Camry. b) Efficiencies in excess of 35 MPG are not extraordinary for a car this size/weight under optimal conditions (60 mph cruise, light wind, mild temps, few brake applications). In fact I'd expect similar configured fwd cars to achieve the same fuel economy. A four cylinder Accord would be the most directly comparable. There are reports of mid 30's fuel economy out of GM FWD V6 vehicles at steady low cruise speeds. The efficiency of the Camry is competitive and first rate, but not extraordinary. |

Replying to: caaz (Jul 29, 2008 3:18 pm) Well - a) unless you have a manual transmission, you aren't going 35 mpg in any automatic camry. If you do, like Troy's manual, you might. b) 200 miles driving of trying to "hypermile" at 60 mph doesn't show anything due to gross errors in refill volume of such a short trip; and you wouldn't be able to get "well over 35 mpg" in that or any other situation. The claims here are made for people going 65-70 mph and getting 30, 35, or 40 in routine driving. Sure, you might come up with an "apparent" 30 or 35 in one tank, but that isn't the true mileage. I don't put any stock whatsoever in a 200 mile drive, so no thanks. Now, if you were to drive 5,000 consecutive miles (mostly freeway, not throwing out the lower mpg tank records)- and keep the records (odometer readings, every receipt of gas), and show 35 mpg, then that's another story. But claiming something on 200 miles is not a true test of "real world" mpg. Lots of people drive 90% freeway - but none of them claim such long term high mileages as their average mpg. What people do claim is that every once in a while they calculate on single tankful that they get thirty this and that. c) I'm not "doubting" - I am making a statement of fact, such as the sun rising in the east and setting in the west, so does a camry get 26-28 on pure freeway. Perhaps a little more (or less, if you are so unlucky to have bought those 5 speed automatics), but not much. Maybe 32 on a pale minority of a few vehicles, and that's a rarity, attributed to some factor about those particular cars that has yet to be identified. But not 35, and not 40 mpg. Not on an automatic.

caaz Please read my posts. I know the Camry can get 40 mpg and 35 is a piece of cake. No need to convince me.
