How Good Is Your Corolla On Gas?

was going to but im not worrying about it right now since it is garaged for for the winter, i just had to make a trip in it real quick and wasnt to concered,

Do you have to get it smog checked?

 

Most of our part of the country doesn't require any emissions testing. Of the 88 counties in Ohio, only 7 require emissions testing. They are the counties that make up Cleveland and the surrounding area. Indiana only requires emissions testing in 4 counties, and Illinois only requires it for certain zip codes in 7 or so counties. Kentucky doesn't emissions test at all because the court held that the Kentucky law that required emissions test was not enforceable. Michigan didn't either the last time I lived there in 2001. Pennsylvania requires testing, but they exempt new cars and cars driven less than 5k per year. Their testing isn't always emissions testing though, some counties only require visual inspections to make sure lights and signals work. West Virginia has never had them at all.

So there you go, pollution isn't a big enough problem in our areas to warrant the stringent controls and inspections that you Cali residents are subjected to every so often.

That results in slightly greater performance (although poor emissions).

Hence, you can remove all the emission components that restrict your airflow in your car.

Last time I checked, tampering with was illegal. It's also inconsiderate for the drivers behing forced to inhale carbon monoxide from your car.

Yeah, while there are no tests required, it is illegal to tamper with or remove emissions equipment. My Uncle has had to put his emissions equipment back on his Jeep after being pulled over on the way to a trail several times (the Jeep is for off-road use, but sometimes he has to drive it to the trail). If you're caught without the equipment they issue you a fix it ticket and then you must put it back on or face a steep fine.

29-31MPG in the city & 36-40MPG on the highway on 91 to 93 pump gas. Even with prices the way they are I still use the good stuff! I used regular 89 pump gas and noticed a loss in MPG, about 2-3MPG. Thats in a 95 DX 7A-FE. With 155k+ miles on it.

2002 S manual. I used to get about ~37mpg with mixed 50/50 city and highway driving. On long highway trips, I could see a bit over 40mph if I drive sane with a tail wind. The worst was about 32mpg. Lately, my gas milage has been declining steadily and I don't know why. It might be the weather heating up, my oem tires getting worn down, or combination of the two. I haven't really change my driving habbits so I am at a lost.

I don't know what you guys are doing, how you drive, and where you live, but on my 2002 CE I get 37-38 miles/gallon in the city and it goes up to 41 miles/gallon on a good day out on the highway. I have a manual (would not even buy automatic), have new iridium plugs and impeccable maintenence (I do my own maintenence). I do not go over 70 mile/hours. It does not worth the huge jump in gas. On the highway I always use my own cruise control that I built in the car (made almost an S from a CE on the cheap) and keep all filters, fluids, and passages clean with various treatments. I have owned GM cars before my Toyota (how foolish I was!) and I am amazed how well this car is built. It is an engineering delight compared to any current American make. Oh, and I don't buy dirty 87 octane gasoline. It is a complete mistreatment of a Corolla. I would buy 95 or 98 if it was available in the U.S. and I could pay for it.

Was wondering how good everyones corolla did on gas. So far the farthest I have got on one tank is 420 miles.

I live in Maine and bought a 2003/auto last year. I'm very disappointed with my fuel economy and therefore Toyota. I do 30/70 city/highway and get 29 in the winter and as high as 33 in the summer. And I don't lie about it to make myself feel better. With acetone added I get 32 and 37. I check it at every fill up and have tested my odometer against 100 mile marker segments of highway. I did better with my old POS 1.6L 1994 Sentra at 34/42. Oh well, live and learn. I'm looking into running a higher water jacket temperature (192º-195º) and perhaps building a fuel warmer. I use a scanguage and am convinced I can gain from higher overall temperature. Where did they come off OEMing this thing at 180ºF ???

There are cars that get better gas mileage available, but I think you like the 2003 for other reasons as well.

I also have 03 auto and average 27 city (heavy trafic) and 31 hwy (driving loaded at 75-80 mpg). People why boast about 40+ mpg drive manual tranny, empty car and very slow speeds. It's hard to compare MPG as it's driver dependant.

Interesting comment on acetone. I tried in my cars with no result. Sometimes I think acetone fools scanguage to display higher MPG.

Did you do research on the car before you bought it, or just expected it to be better than the Nissan?

No, I didn't research it. My Bad. I had previously owned a 1996 Avalon and a 2000 Camry, both V6's, both outstanding vehicles, and I was comfortable buying another Toyota. I just expected more in terms of fuel economy. I'm sure if it was a 1.6L and not a 1.8L I wouldn't be squawking. I have to admit I don't regret the purchase. BTW, the 192º thermostat mentioned above for the Corolla was very hard to find. Struck out at six auto parts retailers. Went to an international parts wholesaler and found a MotoRad for that application. I hope to install it along with a system flush and new coolant next weekend.

I don't use my ScanGuage to determine mpg. I drive until nearly empty and refuel at a handful of stations, parking on level ground and filling to the neck each time... Miles driven divided by gallons used - very simple. The ScanGuage uses the engine instrumentation to calculate mileage. It's close but not as good as repeated distance/usage. My mileage calculations have nothing to do with the ScanGauge.

Regarding my acetone comment, my mileage is on average 13% better with acetone, carefully added at 3 ounces/10 gallons of 87 octane. Too much gives the same results as not using it at all. And don't waste your money on higher octane, the 2003's 10:1 compression ratio can't utilize it. 87 octane isn't dirty, it just has less octane in it.

Gas mileage is very related to driving style. Aggressive rabbit style driving will yield worse results than someone who is very conservative on the gas pedal pressure and speed.

Absolutely true. Unfortunately there are many who think those two pedals belong on the floor. In addition to driving style, there are many other variables as well. Many of them often get missed.

On another note, I'm replacing my two rear-deck speakers this morning. The stock ones where blown when I bought the car. Shame on Toyota for all the work that will require!
