I did the trip computer mod to a loaner car, just hold FM/AM and CD after you turn it to ACC. Worked that way for me on an 08.
weird MPG
- Thread starter evil-98
- Start date
the 2.3L non turbo should be using 87 and only 87. a higher octane on stock everything will cause minor engine damage, and possibly bad gas milage. a higher octane DOES NOT mean the fuel is of higher quality or is better in anyway. It just burns differently. if you have done monzta's timing mod, you should be advanced in timing 1 to 2 degrees. this would allow a 89-91 octane and possibly 93 if you would so desire. the only reason i would run 93 is if your running nitrous or an aftermarket turbo.
now then, at 9k miles at 1k ft above sea level, i get about 24mpg half city half highway driving, flooring it at least 5-8 times a day. i am not easy on the car by any means. i also have a 2 degree timing advance and am running 89 octane. i was previously getting 22mpg before the timing mod while running on 87 octane.
okay, theres my bit. any questions?
edit: the trip mod does not work on later model 08 and pretty much all 09 mazda 3's. mine is not even that late model 08 and it does not work.

i just read this.
you do realize your temp gauge in the car is related to the coolant temperature, and has no relation to your oil right?
whats even funnier is that 0w-20 would be a better oil to use than either of those, but i guess i shouldnt get into details.
i also noticed how much the offset on the stock fuel gauge is. ive figured out how to get a quick estimate of gas milage. *this is not 100% accurate but it comes close* watch your milage reading at 1/4 tank remaining.
if at 1/4 tank u run say 241.6 you are getting close to an average of 24mpg this actually works out pretty nicely. but the best way is to still measure gas put in to miles run.

Naw I totally forgot. It's funny cause I've helped replace a couple temperature guages and had to drain coolant. But whatever, my gauge is still bouncier now that they took out my fancy oil.

...enough information to make your head bleed. (confused)
Regarding gauge precision (fuel, temp., etc.)..
It might help to remember that, figuratively speaking, they're not marked in micrometers, so trying to measure their readings in micrometers is largely pointless -- they are just not precision instruments. If you want more precise readings, you could get a ScanGuageII or a DashHawk which will read out data directly from the ECM/computer through the OBDII port.
Or, you could forget about it and just drive it. (drive2)

Yea it's not worth it, the car won't be in my possession for much longer I'm hoping.Regarding gauge precision (fuel, temp., etc.)..

Thanks though!
gotta compare ur milage to how much u filled up, not how big ur tank is......anyways ive noticed i get better gas milage when i beat the snot out of it too, like not "hard" driving, but WOTing it a lot. ive heard that an engine is most efficient at WOT. so it makes sense. screw it, imma have fun the next couple tanks and see what i get, i get 23-24 driving normal/lightly hard. i got 25 a few weeks ago when i street raced a little.

Just let it wind out sometimes, this is what I've been told. If you let it run all the way up to the red line then drive it nice and smooth it runs more efficient. I wouldn't know, I've tried both ways and get crappy gas mileage either way so it's all on your call with this one.

Well, on the bright side, your car is holding together much better than mine has and yours wasn't in the shop for the past two weeks and Mazda didn't invalidate your warranty on half the car so small increments of increase sound pretty sweet to me!

I makes prefect sense, I totally forgot that the temp gauge is in the coolant although I've replaced a couple of them. Mazda screwed up and replaced my full synthetic heavier weight with their crappy stock weight and synthetic blend so no my engine is running a bit hotter everywhere and the temp gauge is a lot bouncier.
