how much more gas do u spend in mivec i hear everyone always saying they try to stay out of mivec in the highway. now from my understanding mivec kicks in from like 3500 to 4000k now for me that is like only 70mph, i am usually driving inbetween 80 to 90ish on highway each day to work. im just curious?.

 

stay right under 70, and your gas mileage improves dramatically

 

not much

 

Believe it or not it makes a difference. On my way down to San Diego i was cruisin at like 80 - 100mph and i got horrible gas mileage. Somewhere around the 18-19mpg. But on the way back up to the bay area i stayed around 65-70 because of rain and i got right around 25mpg. So just slow it down a bit an you will see an improvement.

 

i believe u guys i just cant drive that slow, first of all the speed limit here on the highway is 70 but thanks for the info, just wondering

 

it really does help the mpg if you keep it under 70mph , you're lucky the speed limit is 70 where you live here in P.R its 55.

 

yea i understand that i justb like to go fast, and about the highways here we have diff speed limits, ranging from 55 to 70 but the one i use to go to work is 70.

 

+10000000000000.645

 

you sure bout those numbers

 

on my RA, I can go 75mph when the rpm is right at 3500, so I say between 70-75 is good! And plus, u can hear the mivec turn on once you reach that point, so just stay right under it!

 

That's still pretty low. I can get ~30mpg when I do ~74mph and stay out of MIVEC, and ~25mpg around town. I even managed 33mpg once.

on 87 octane

 

33 mpg nice !! Although prices aren't going up i still spend like 30-40 bucks a week on gas for my car.

 

haha, RAs are gas hogs! lol. We're just as bad as H2 drivers, lol

 

I've always stayed below 75mph while cruising, anything higher could be pretty wasteful for no real gain. Of course when I want to go way faster than MIVEC change-over speed in 5th gear, I'm not in 5th gear for most of the time... if you're gonna pour gas into the engine, might as well make it worth it!

I find that cruising with CC on at ~72mph with no A/C yields pretty decent mileage.

 

stay below 3600 and youll be fine.
i learned the hard way. i literally watch my gas needle drop going 85 on long trips.
