It does not take much city mileage to really hurt the highway mileage. Really it makes more sense to compare the amount of time driving each not the amount of miles (if you are estimating). You can drive 50 miles hwy and 50 city, but if the highway takes 45 minutes, and the city takes 3 hours, then the vast majority of your driving is in the city. It is gallons used in city vs gallons used on the highway that is important, not the number of miles driven. Say you drive a car that gets 25 mpg on the highway. 50 miles is 2 gallons. The same car gets 10 mpg in the city and uses 5 gallons. If the miles driven was a controlling factor, then the mpg should be 35 mpg (25 + 10) divided by 2 or 17.5 mpg, since equel miles were drivin under each circumstance. In reality the car got 100 miles divided by 7 gallons, or 14.3 mpg. Don't forget you can't really compare city driving, unless the same person drives the same route under the same conditions. Highway is more repeatable, but there are still plenty of variables. |

Replying to: phd86 (Mar 14, 2006 1:35 pm) I did keep some pretty detailed mileage logs for the cross-country trip, but I didn't specifically log miles driven in towns vs. highway mileage. My mileage recordings had the start and end points for each day, as well as key intersections, state lines, larger towns, points of interest, etc. along the way. Here's what I have (again) on the '04 Camry: 04 LE 4 cyl 4A: Overall mileage from 19 miles (new, with a full tank of gas) to 15,802 miles: 27.3 mpg (15,783 miles, 578.84 gallons) Best 3 highway mileage readings in that period (with 2 consecutive tankfuls): 35.5 mpg (709.5 miles, 20.01 gallons) mostly freeway 34.9 mpg (815.1 miles, 23.37 gallons) mostly freeway 30.4 mpg (686.9 miles, 22.62 gallons) mostly divided highway w/ traffic lights. Worst 3 city (small town in our case) mileage readings in that period (single tankful, but at least 10 gallons added): 22.4 mpg (234.6 miles, 10.47 gallons) 23.1 mpg (267.1 miles, 11.54 gallons) 23.1 mpg (241.0 miles, 10.45 gallons) I cannot do what you asked (drive the car only in town for 3 weeks), since I have to go to work. What I am going to do, which I said before, is use the '04 Camry for commuting in place of my '98 Nissan Frontier, which got 26 mpg consistently (tank after tank), because it was driven almost the same way for each tankful. We'll see if the '04 Camry can do better. I also will follow up on the overall mileage to date (excluding the time my son had the car) on the '04 Camry, now with 34,600+ miles, as well as info on the '05 Camry, which now has 11,000+ miles. As I said before, the '05 Camry definitely does not do as well as the '04, even though it has the same engine (but 5-speed auto instead of 4-speed auto).

| Data looks good to me. Splitting hairs to need more accuracy than that. You can never accurately compare city between two different routes, but will be interesting to see what the commute in the Camry yields. | |

Replying to: mattgg1 (Mar 16, 2006 10:21 am) I'm wondering if the break-in procedure for the two cars was different enough to cause it. (One of my earlier posts in this thread explains this.)

Replying to: 210delray (Mar 16, 2006 10:45 am) I'm very curious about the break-in procedure for new cars. Could you tell me the post # of the thread you are referring to? I've never owned a new car, so I've never had to worry about the break-in. However, I will be purchasing a new Camry or Accord (I haven't decided yet) soon, so I'd like to do whatever it takes to maximize fuel efficiency for the life of the car.

Replying to: 210delray (Mar 15, 2006 7:16 pm) You live in a small town, probably minimal traffic at all, you need your car to commute, and so your reports (in my opinion - and I'm sure you'll address this) vary from alot of freeway driving to a heckuvalot of freeway driving. 22-23 mpg in small town driving, with someone going to work 5 days a week - I'm thinking there is some freeway driving in those city tankfuls. Is that true? It will take 4-6 weeks to get you some comparative numbers on shell gas (my current tank is Arco). Its not a matter of "believing"; you didn't record your relative freeway and highway driving. your 27 mpg , if predominantly freeway, is not out of line with the predominantly freeway mileage I get (for me, I would get that in 85% or more freeway). I think I drive more city than you. As for your posts of 30-35 mpg. I have three things to say. One is WOW. The second is that is your best mpg, not your average (27 mpg). And the third is that your indication of 20-23 gallons of refill, which exceed the specification of 18.5 gallons, gave me some pause. I've run tanks dry on rare occasions, but I've never been able to put much more in than the specification. I look forward to your explanation/response.
