From: Stan Wright on 30 Mar 2008 12:13 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........ Stan

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.

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.

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.
