Many states, including mine (MN), have so-called "winter gas" i.e. up to a 10% ethanol blend year round now. The formula might be tweaked a bit for winter, i.e. to make it vaporize more readily in cold weather, but there's not the big difference any more between summer gas and winter gas, at least not where I live. I did notice though when I was driving through WI a couple of summers ago and filled up at an E0 pump that my fuel economy for the trip home seemed about 10% better than the trip down. Part of that might be attributable to other factors, e.g. having the A/C off, but I bet some of it was the gas.

Toyota Corolla S 2009 fuel economy problem

Hello, I need some assistance with a gas mileage issue I'm having. I purchased a brand new 2009 Corolla S around the beginning of november 2008. I 've traveled about 580 miles on the vehicle thus far, city driving mostly and some highway.
The rating is 27 city and 35 highway. I understand the fuel economy varies based on driving habits and conditions but I'm only getting about 230-240 miles on a full tank of gas. Thats about18.2 miles per gallon right? (240miles / 13.2 gallon tank =18.18 mpg) I haven't done any crazy driving with my car. I don't think there's anyway I should be getting such poor mileage on a new corolla. I don't expect 27 city but I should be getting over 23 mpg right?
I took it to the service station where I purchased the vehicle and informed the serviceman what my problem was. He refused to look at it and told me "you need to break in the car some more, 3 to 5 thousand miles and then you'll see it." Is he being truthful or just blowing me off? I don't know much about cars but every single older model toyota I've driven has given me better fuel economy. Maybe I'm wrong and my economy is suppose to improve after I break it in more. I hope this is the case but I am not sure, thats why I'm asking.
Note: I use the type of gas I'm suppose to.- (REGULAR)I've different gas stations as well.
I need some guidance, please help me. thank you for your time.

Your calculations are flawed. MPG is calculated by the number of miles driven on a tank of gas that you actually are pumping, not the size of your tank. In other words start with a very full tank of gas and start recording your driven mileage immediately. At next fill-up take that number of driven miles on that tank and divide by the actual number of gallons you pumped into your tank on this next fill-up, not the tanks size. This is necessary because you will always have some gas left in your tank even if driven to what you think was empty.

Yes and No even in my break in ( I now have 7000 K) I was getting 27-30mpg range but now 35mpg on a 70 hwy 30 City driving. I would do a few more tanks to verify it. I hope you didn't count the tank it came with as they are NEVER all the way full.
Good Luck

Thank you both for your responses. I ran the gas pretty much down to empty but I'm going to try a few more tanks and calculate it the way you told me to and see what I get. However I seriously doubt its going to result in 26-27 mpg though. Guess time will tell. thanks again I'll post again when i get the results.

No, you won't get the 26 to 27 mpg. your looking for with your city driving but unless you were able to actually pump 13.2 gallons into your Rolla your calculations were inaccurate. By the way, I also have a new 2009 Rolla and do 95% city driving and can't get better than 23 mpg. in the city. I wasn't expecting better though as I have a 2001 Rolla that also gets the same. Now get them on the highway and I can push 40mpgs. no problem.

We have an '09 le corolla. Mpg was 28.5 in town until 10% alcohol was added to all gas available in Florida. It then slipped to 25.0 mpg. Our latest highway calculations were 39.1 and 40.5 mpg at no greater than 60 miles per hour. Faster speeds reduced mpg to 35.7 and 34.9. Those speeds were as great as 80 miles per hour. I used traditional methods to calculate mpg. PS Our car has 3792 miles on it; I have recorded every drop of gas put in this car.

Yea, that sounds right in line with my city MPG. We also have 10% Ethanol in our gas in PA plus I have a lead foot in the city so I get 23 MPG. or less.

Your mileage will vary, but with my 09 Corolla I havn't gotten less than 30 mpg with my day to day driving, even when the car was brand new. After the first couple of tanks of fuel, I'm getting 35 / 36 mpg just driving to work, but I do drive the legal speed limits. The most miles I've gotton out of a tank of fuel has been 480 miles in the summer months. I did notice that using the air cuts about 2 mpg . I have not even tried the car on a long highway cruise, but I'm sure the car will get over 40 mpg on the highway.

Now when you say day to day driving is that the 5 to 10 minute trips of mostly city driving we were comparing or is that some highway?
