Wasnt sure which sub forum to post about MPG...

I own 2011 Toyota corolla LE and I live in southern California.

Curiosity- is there any way to maximize the car's MPG? Gas prices here in so.cal are going up and I want to see if there are any efficient ways to improve the MPG. I've been taking care of my car and I do not drive it all crazy like some drivers out there.

Maybe removing some things that are not necessary for the car?

Any ideas?

Thanks in advance! :)

Well Hello From LA.

Well I can average about 34-40 mpg in this unholy LA traffic, but you gotta drive like the Tortoise, not the Hair.


Things to do:

Well for starters, don't be lead footed and "try" to drive at a constant speed.
Cruise control does help, but i find that if your good at maintaining your speed w/o cruise it'll get you a few more mpg's
Drive with the windows down, while in city/stop and go traffic.
Add 1 or 2 psi more to the tires, I add 4 psi. Make sure the air filter is clean.
Waiting at long stop lights, shut off the engine. hence leaving windows down.

Things not to do:

Go on a diet.
spend a couple g's on a aerodynamic body kit.
put diesel instead of gas.*
walk.*


*I recommend never doing this

Also, make sure to keep the car aligned. Out of alignment tires kill mileage as well as tires.
Remove any excess weight not needed from the trunk. Excess weight decreases mileage, especially with this small of an engine.
Keep the oil and filter changed and use the recommended synthetic oil to reduce internal drag. Keeping the transmission fluid changed at recommended intervals helps keep friction at bay in the transmission. Very slight improvement here, but it's something to keep in mind.
If at highway speeds, roll up the window and use the AC if needed. Tests have proved that open windows at highway speeds hurts mileage and the newer AC compressors aren't that bad on mileage. If you can avoid using the AC, by all means do so!


There have been reports by some that the addition of an intake system, either CAI my way , or an aftermarket type have seemed to help mileage some. If using the stock type of filter, keep it changed/clean. There were some that reported a slight increase with a freer flowing exhaust such as the Borla or Magnaflow. How much they help, I can't say as I'm still waiting for my intake and exhaust to arrive so I can do my own tests. Others will have to chime in on these.

Good luck and keep us posted!

Thank you for your responses.

All maintenance has been done thus far, so the car is running good. I can't think of anything else to improve my car's MPG. Horrible traffic in LA makes it a little hard because you can't really cruise at a constant speed some of the time so that's where alot of my gas goes. Just idling in bumper to bumper traffic and all those stops on the streets.

I was thinking of getting the Borla exhaust, I heard great things about it and I've researched a bit on it. Money is a little tight since I'm in college so that will have to wait.

Let me know how your intake/exhaust is! I'm curious to hear! :D

1st day

So far theres a considerable increase in throttle responsiveness along with a throatier sound coming from intake, and +2 mpg so far, but will see if theres even more of an improvement as my drive to school is only 15 mins so if there was more of an improvement to be had it has to wait until i get out:thumbsup:

I also have a 15 min drive to school..then i'm stuck there all day for my classes lol but that's great! I'll have to tackle that mod this weekend hopefully when I have some down time from work and studying.


I've heard that AC does not "eat up" the gas. Also heard that rolling down the windows while driving may/may not be as effective as everyone say. Dunno which is true but I'll have to see for myself or if others would like to chime in on this would be nice. So far, using the AC in this hot California weather doesnt have much effect on my car's gas.

UPDATE: +4 MPG and holding!! And if you need any help with the mod or have any questions you can always private message me or p post on here and I should reply quickly. Other than that let me know how it goes!!

Also keep in mind that it's pointless to spend a bunch of money with intentions of gaining just a few mpg....

assuming you drive 15k miles a year, with an average of 34 mpg, you're going through 441.18 gallons of fuel a year. Multiplied by $4, and your spending $1764.72 each year on gas...

Driving the same distance with an average of 38 mpg, you're going through 394.74 gallons, which is $1578.96 at $4 a gallon. That's only a difference of $185.76... Just something to think about before you start spending $$$ on parts in attempt to save money on gas (I'm not saying you are going to do this, just wanted to toss this out there).

Thanks for the heads up, I'm not going to spend money solely on ways to improve MPG. But that is interesting to see we'd spend that much on gas, if not more.

Also keep in mind that the mod in question is 100% free because it involves removing stock parts without adding any aftermarket parts, so as far as I'm concerned thats better performance, better mpg, and $185.76 in my pocket...

there are always cheap mods that can improve HP and mileage on most cars. most of this stuff that hurts mpg and HP are there for emissions requirements when the car was new. almost none of this will affect passing emissions in your local area if you even have to pass emissions.

True^ I live in texas and its been raining non stop for like a week and a half and no probs yet despite driving in heavy texas rain, the intake is still in front of the bumper lip so no splashing etc. but just to be safe I'm getting a hydrogaurd and securing it with a hose clamp :D

ultimately it comes down to how you use the gas. when I'm in LA rush hour, I just let the car roll. I don't really care what people behind me think, I'm not going to touch my pedal unless traffic really starts moving. I think the max idle speed of the car on a flat surface is 8-10mph at least in my case.

My commute has hills and lots of wind, I try to combat those by going 55mph. As a result my last highway tank was 42.376mpgUS, this tank I fell to 41.267mpgUS..I have come close to the Prius rating of 48mpgUS...but never beat it...:disappoin

The EPAs testing procedures are pretty strict, in a controlled environment dyno that simulates real world driving. For conventional vehicles it is like this: http://www.fueleconomy.gov/feg/fe_test_schedules.shtml average speed..about 48mph for the highway driving cycle. So in real life with wind, hills and weather, my car beats the controlled condition testing results and I even go faster and further on a car that is way older with 144,000 kms...as for hybrid testing, not sure...but we can rest easy knowing that the methods should be comparable otherwise the ratings are useless.

In the end, the EPA numbers are pretty close to what the average user is getting on their hybrids...and seem to be the case for what you are getting on yours too ;)

If you just drive the Prius normally it's pretty easy to get 48-50 mpg which is right in the range of the EPA. I can get much better mpg when I drive it but my wife drives it 95% of the time & she doesn't practic any technics to improve mpg. I average close to 55-58 mpg when I do get to drive it. :D

Haven't got to the mod (CAI my way) yet, but today i had a chance to drive on an open road and had my cruise control on (ranging from 40-55 mph) and my "current" MPG was displaying 40.2-68.7 MPG. So from my MPG being 24.6, it went up to 24.7. Not so much change, but I am still trying to practice my technics to improve my corolla's MPG. Still waiting to do the mod, maybe I'll do it this week... So. Cal gas prices in my area has shot up to $4.33/gal. And that's only unleaded

Holy Moly! I just filled up my tank today after installing the Takeda SRI.
The previous tank MPG was 38.9 MPG. This most recent tank was 42.9!
I've never gotten that high on this car...ever!
I do try to get good mileage and try to anticipate the traffic ahead but this jump is totally unexpected! I will need to track this for a few more tankfuls to see if this is real or a fluke occurance. I'll keep ya all posted!

Is there a thread on Takeda SRI? And did you have to buy anything to do this mod? (sorry not too familiar with sri) but when you see more results let us know how your MPG is. Right now my average is 24.7 (haven't did CAI my way mod yet, or any other mod. Just trying to practice my technics on improving the mpg.)
