The advertise of 36mpg is usually factored in at roughly 60-65mph if I'm not mistaken. I have a 2013 Corolla S and going at about 75mph I average about 25-30mpg. You also have to factor in the inclines and declines of the road as well. Also what is your RPM's at when you drive 75mph? Mines is between 3200 and 3400 RPM's. Usually I stay at 65-70mph on the highway because that's usually when cars get the best mileage out of the cars.

 

Thanks very much for the quick reply. The one thing I did neglect to mention was the rpm's. Here they are.....
50mph=2,000rpm
60mph=2,200rpm
65mph=2,600rpm
70mph=2,800rpm
75mph=3,000rpm

 

That's still way off.

What is your tire pressure set at? Is it cold where you are? Are there lots of hills? What happens if you do say 70MPH? If you have the car in drive at a stop and let go of the brakes, does it roll forward fine?

My advice, disconnect the negative battery terminal for around 10 minutes and then hit the brake a few times to clear the ECU memory. Reconnect the battery and drive normal so the car relearns your driving habits.

Then switch gas stations if you haven't already.

Something isn't right here.

Just saw you are in FL. Cold is likely not your problem.

 

Wow, very interesting stuff. I'm in So. Fl., so it's pretty much flat driving and of course saying I'm in So. Fl., answers the weather question. And it does roll forward fine from a stop. Tire pressure is at 32. Might try the 70 mph thing on Monday. I have noticed in the mornings when I 1st start it, it idles, what I consider to be high, and I can hear the engine speed changing up and down, and can smell a bit of "richness" as it's idling. It takes a little bit for it to settle down, but as best I can remember it still idles at about 900rpm, which I think is way too high, even if it is a 1.8 litre 4 banger. I'll do the battery thing this weekend, when I fill up on Sat. or Sun. If I do that it won't harm anything will it?

 

I would experiment. Try driving a complete week at 65mph and check the results. The next week try 75 mph. I see a huge drop in mpg on my Scangauge from 70 mph to 75 mph. At 65 mph the mpg is much better. I would also increase your tire pressure to at least 36 psi, that will also help & help reduce hydroplaning on wet roads too.

The idle speed is normal until the engine warms up so nothing to worry about there.

Keep filling up ever Saturday & comparing mpg from week to week & see what these different speeds produce. It takes a good 10 miles for all fluids including oil to get up to operating temp so you aren't going much farther to get a lot of miles at the full operating temp range.

Have you ever gone on an extended drive on the weekend? Go for a nice long drive & check your mpg over the trip. You could also invest in a Scangauge & se what you are getting over every trip, day & tank of fuel. :thumbsup:

Keep us posted!

 

No, you will be fine.

 

It sure sounds like you should be getting better fuel economy. I have a 2013 S automatic and have tracked every ounce of fuel I have burned since it was new. I am also a daily commuter of I-95 in Florida.

With varied AC use and doing a steady 70 mph, I average around 34 mpg. It seems to get better when it is really hot outside. Of course going slower and using less AC, it will get a few more mpg's. My all time best was just over 40. All of this manually calculated, (I have noticed the on board fuel economy numbers are higher.)

I say all this not to brag but to offer some info as to what these cars can and do achieve... it sure sounds like something is wrong there. I will check on mine, but it looks like your rpm are about right. Hope it gets better for you as the miles add up.

 

My car when I start it before warming up is roughly 1100RPM's. After warm up, it's about 800RPM's. How do you drive before making it to the highway? Do you have a heavy foot taking off after a red light or stop sign? Your fuel could also be burned up in that amount of time. Ifyou jhave a slower take off, it can actually save you quite a bit. Slower take offs made me go from about 270 miles a tank to 310 a tank.

 

Another vote for slow takeoffs, they help me. Maybe you have a dirty MAF sensor. Keep it simple!

 

Give some of these tips a try...some are pretty obvious...others not so much. I utilize a bit of these to get the results I do (see signature) as I was doing them subconsciously over the years. I don't do the the extreme stuff, but most of it you can do and still drive normally.

I have a 2010 Corolla LE with about 58000 miles and currently get about 25 mpg average in the spring/summer and about 18-21 mpg average when they switch out to the winter blend of gas.

 

Thanks everyone for your suggestions and input. Really appreciate it and will attempt to implement them. The increase in tire pressure is something I've been meaning to do. I would like to do a little trip to cost someone in Orlando, and check the mileage, but with grad feat approaching the $4 per gallon mark, that's not going to happen. Ifiled the ttank yesterday, Sun, at $3.80, so I'm willing to bet that by next weekend it will be at $4 or over. Anyway, that's neither here nor there. We can't do anything about it, no matter what the price goes to! I'll keep you posted.

 

Mileage may not be that far off. Matrix is a lot of weight for the 1.8 to be pulling around.

 

Good morning all. Well so much for doing 60-65 on I -95 to test or check my mpg! It's just not going to happen. Aside from feeling like I'm driving in reverse with the brake on at those snail like speeds, it seems as if it takes forever to get to work, even though it's only 16 miles each way. So whatever my mileage is going to, it's going to be! 'Cause doing 75 or more is what it will be. And it seems the car gets up to that speed fairly quickly, considering the Singer Sewing Machine engine it has! In the grand scheme of things, none of this matters anyway, since this car was/is just a means to an end to help me with my crap credit! In 2 more months the car will be a year old, and by the end of the year, or a little b4, I'll probably have a 2014 Camry. The company I work for uses Toyotas as "pool cars" for employees and company execs and customers. So the max mileage they see each year is maybe 3,000-3,500. All the Camrys are the SE model. Already have the one picked out I want and they said no problem. It's no so much that I want another Toyota, never wanted, or thought I'd ever own a Corolla, but the deal is too good not to own one. And again I'm rambling. 'Cause I'm sure none of you even care about all I just said. But thanks for listening anyway.

 

Hello to you, as well. It's too bad you feel this way. These members were only trying to help you, with your issue of lousy? mileage. Maybe what you were/are experiencing would be of help to other owners. That being said, it's good that you're enjoying your car, even if the mileage may not be up to snuff, though going 75 or more, not only causes a decrease in fuel mileage, but always more wear on the engine as well (due to increased wind resistance). Those folks you see going 75+, the majority will probably "dump" the car in a year or 2, and the next owner will deal with the consequences of these high speeds.

 

I'm frustrated myself with my 2010. I'm thinking of going to maybe get a Camry too. Or maybe the 2014 corolla might get better mileage due to the fact that it has a cvt transmission. I dunno.

Way to go! On highway, Camry will have better gas mileage than Corolla.
In fact, corolla is not meant to be driven over 75.

 

In fact, corolla is not meant to be driven over 75.

:rofl2: The Corolla drives great at 75+ mph. I've had it cruise at 80+ in states that have a 75mph speed limit with zero issues & she drives & rides great. The Camry, Corolla & any other car though WILL suffer worse mpg at 75 mph than at 60 mph, simple psychics nothing more, nothing less. It simply takes more energy to push the car through the wind conditions at a higher speed thus using more fuel.

 

Thanks for the vote of confidence Creepy Dude! I do like my Corolla, and I feel badly that is not it's fault it was built the way it is. And believe me, I've never "hot rodded"or "dogged"any vehicles that I've owned. So if I'm able to make this happen by the years end, it will be done. And the SE Camrys we have here on site are very well cred for. They are always housed inside a hanger when not in use. So, thanks again. I'll post periodic updates as to what's going on. And my thanks to all who commented and advised.

 

the vast majority of one's results when it comes to fule economy is due to driver behavior. yes properly inflated tires, regular maintenance, and other bits can be done to help but it really comes down to your right foot

 

Agreed.

There is no car on the market that will get good fuel economy if you don't drive conservatively. Even a Prius will get garbage numbers if you bag on it:

....ffwd to 4:17 and really pay attention to the statement made at 5:50

 

Agreed

From the article:" http://www.foxnews.com/leisure/2014/04/30/gas-saving-tips-myths/?intcmp=features" ...

"Slow down. In our tests, we’ve found that driving faster on the highway can really take a bite out of your car’s fuel efficiency. We measured gas mileage while driving at a steady 55, 65, and 75 mph in a Honda Accord, Toyota RAV4, and three versions of a Ford Fusion, including a hybrid. The drop in fuel economy while going from 55 to 65 rangedfrom 4 to 8 mpg. Upping the speed from 65 to 75 cut it 5 to 7 mpg more. Overall, speeding up from 55 mph to 75 is like moving from a compact car to a large SUV."

Ouch.:wowza:

 

I have a 2009 Corolla LE and my co-worker has 2010 Corolla S both automatics. We basically do the same commute every day (we live within a mile of each other).
His 2010 gets on average 34 mpg
Mine gets 23 mpg.

My car has 92k miles his has 53k miles.

The distance is about 10 miles each way, all mostly city driving (Northern Virgina, Fairfax area).

I use Shell 89 Octane fuel. I have tried everything with the car.
I have cleaned the MAF, the Throttle Body, changed the engine air filter, using only 0W-20 Synthetic oil (change every 3.5 to 4k miles). Have added Fuel Injector cleanered to the fuel: Have tried BG44k, Red Line SL-1, Techron Concentrate. Added Liqui-Moly Ceratec to the engine oil to reduce friction.
Now Changed the Bank 1 Sensor 2 for Oxygen sensor.
Drained the Transmission fluid, dropped the pan, changed the transmission filter and refilled it with the Toyota ATF.
Changed Spark Plugs and used the Toyota OEM Iridiums.
Reset the ECU.
Tires at 35 PSI.
Nothing!

Also the car IDLE will fluctuate from 600 to 900 while at a stop light. It will keep rev up and then rev down to the point where it feels like the car is about to turn off and then it will rev back up again.

For mostly city driving it can easily be 23mpg, especially in mountainous area.
I wonder how your friend achieved 34?

 

speed makes a huge difference on gas mileage.

 

i noticed constant 55-65 is where you get the 40mpg or more. I manage to get over 200mpg before the guage hit half driving at 55-65.

 

I've never had a tank where I didn't get more then 200 miles by half a tank. Normally I see 225-250 miles at the half tank point. My best was almost 300 miles. At just under 1/4 tank it takes me around 10 gallons to fill up & I'm usually around 350-380 miles. Today I filled up after going to Seattle & back. Highway speeds were between 62-73 mph & I even had the a/c on today. I traveled 340.7 miles on 9.1 gallons for a 37.4 MPG average. It's just not that hard & that was on my summer 225/45R17 tires.
