Bought my Camry SE in July, 2007--4 cyl. w/ auto. transmission.
Traded in a V-10 Dodge 4x4 for mileage reasons--went in to get a
Corolla, but figured for a little less mileage, I'd get a larger car
with more comfort and a body style that I find much more attractive than
the Nissan or Honda "equivalents." Anyway, on to the mileage
question.....

At the time of purchase, I had a 77 mile round trip to make daily for
work--about 7 of it city driving, 10 of it highway, and the remaining 60
interstate highway. Because I figured out the time differentials, the
difference between driving 75 on the freeway (70 limit) and 65 was about
3.5-4 minutes difference; I kept it cruise-controlled to 65 mph for the
trip and let the cars pass me (3 lanes on the interstate for 50 of the
60 miles). This being said, 30-31 mpg avg.......Trips outside of this
steady "study," and using speeds of 70-75 (not many of them to make a
definite "claim") usually knocked it down to 28-29 mpg.

I have since moved and my driving is now primarily city driving (7
mile round trip to work) where the car does not get properly warmed
before it is time to shut down and go into work--it has cut my mileage
dramatically. I have been doing this new routine for four months now,
and have been getting 3-4 weeks between fillups (as opposed to every 4-6
days before), and have been seeing 20-24 mpg.......Still much better
than the 8.5-10 mpg I would've been getting with the V-10........

Hope you find this helpful........

Just a caution about your current driving regime: it's very bad for
the car. You can help some by using synthetic oil, but you really need
to find a way to get the car fully warmed up before shutting it off.
Idling it isn't usually recommended, but in this case try idling it for
5 minutes before leaving for work, then running it at 3k RPM for 1
minute when you arrive, then let it drop back to idle for 5 seconds
before shutting it off. You need to get rid of all water vapor and
condensate in the oil.

How many minutes does it take you to drive the 3.5 miles (one way) to
your work?

How much water vapor is in the oil anyway, and how much vapor is taken
in once you drive the car or park it for a long time? Perhaps once a
week is evaporation ok? I mean If he drives the car during the
weekends and runs it fairly long enough to evaporate the water vapor
in the oil.

When the engine isn't usualy warmed up, hydrochoric acid forms in
the oil, and stays. While not quite as bad as it sounds, it definitely
shortens engine life. Not warming it up once a week is *far* better than
warming it up fully just once a week.

Takes about 12 minutes to get to work.....

Even on the coldest days this winter, by the time I got to work, the
heater was blowing hot air--the engine was warm, just not warm "soon"
enough to get "good" mileage. Wear on the engine? Possibly/probably,
but I am not going to walk to work, can't ride the bus, and there is no
one to carpool with.....Ya gotta do what ya gotta do.....

I am making sure that the oil gets changed right at three thousand
miles, rather than letting it slide a few more since I was running
primarily highway miles with an engine that had plenty of time to run at
proper temps before. Oh, and while the primary use of the vehicle is
for work, I do have days off and have opportunities to regularly get the
engine up to proper temps for long enough periods to burn off any
"impurities." Thanks for the concern and comments--It's pretty cool
knowing that the readers here are concerned for the Camry's of others!
I was just letting the original poster know what kind of mileage my '07
gets, and what kind of driving I do to get it.

Finally, I went for a 200 mile road trip on Sunday--snowing, temps
in the low 30's, wet roads most of the time, two-lane U.S. Highways,
cruise-controlled at anywhere from 63-68 mph, non-studded snow tires on
the car (Hankook Ice-Bears)--29.8 mpg.

Talk later!
