2007 corolla 44 mpg 5-speed

[digitalness]

OK well the best way to save gas is to drive slower, however as of late i have seemed to max out my gas mileage (I CANT DRIVE ANY SLOWER, im not an *** either ;( ).. i cant really do anything else to better my records of 39.5 city and 44mpg US hwy.... i have created additional ground to frame, and disabled daytime running lamps and never go over 2500k rpm...

my question is can anyone reccomend plug wires (bosch type) or even a better spark plug that works with a 2007 corolla? or is that not a good idea seeing as though these cars come with iridium type...

thanks

[digitalness]

just to rephrase, not just any plugs or wires but some that would be specifically used to improve mileage.... also any other suggestions on better FE would be greatly appreciated

That mileage seems pretty good to me. What is your average speed?

average speed probably about 45 stop/go to get that 39, about 60mph hwy to hit 44-45, yea im happy with it too however, its become somewhat of a hobby to get even better gas mileage, just recently switched from 5w30 to mobil one synthetic 0w 30, yet to record a difference actually just did it yesterday... wonder if that will make a difference.... seing since the 5w 30 was also mobil synthetic

Plugs and wires replaced early are never going to pay for themselves in FE. Expensive oil won't pay for itself in FE, but it will in longer service intervals if you use it that way.

Have you increased the pressure in your tires, tried Pulse & Glide, put together a Warm Air Intake, blocked your grill, done any aero mods, etc?

2500rpm is an awful lot. I don't know how torquey the Corolla's engine is, but my VW's 2.5l is good for shifting at 1300rpm on level ground. Wider throttle + lower RPM == better. Try to keep it under 80%, though; somewhere above there, the computer will stop trying to make power efficiently, and instead will just make as much power as possible.

try Kiker Performance wires (google it, dont' have the link handy), I'm not using it yet but I plan on getting them. currently using Taylor Thunder wires been good for me for the past three years. Halo sparkplugs working great for me too (greenplugs.com).

Torque in the Corolla's isn't so good below 2000 RPM, 2500 is just right for normal driving. Try slowing down to 55 MPH on the highway if you feel comfortable enough, otherwise you'll have to all out crazy with hypermiling mods and the such like most everyone here.

And yeah 40 MPG in the city, you're a god to me man that is schweet.

I'm still running original wires in my saturn. I check them for resistance when I change the plugs. 1000-1500 ohms per foot is fine. I find that OEM GM wires sometimes last well over 10 years 200k miles. Its unlikely gimmicky plugs or wires will do anything for FE.

Nissan factory wires were date coded. We replaced the engine and fuel injectors on one that was 17 years old and found it had the original plug wires. Advised the owner to replace them but could not tell any difference in performance.

has toyota changed that much in 7 years? i shift near 2k (except 1st to 2nd where 2500 is needed) in my 2000 prizm(toyota motor/tranny).

50mpg is not hard to achieve in this vehicle. We have the same vehicle (07 corolla LE 5spd power everything / cruise control) with mixed city driving never over 60mph highway (mostly 55 with cruise control) I achieved 53 over a tank. This included ICE off coasts around town. My father commutes to work in it and he only sees 35ish (he drives inefficiently). When we filled it and did the math he was blown away, and started asking questions about how to hypermile. Keep in mind also that the odometer in this car does not spin while neutral coasting ICE off and key off. I turn the key back on after sufficient time to allow the engine to stall but its possible 1/10 of a mile for every ICE off coast was not logged. So it could have been slightly better. Keep up the good work!
