91 switching to 89

[Vgandoza]

Currently using 91 I've been using it for a year on my 2010 mazda 3 gx. Has anyone switch from 91-89 with no problem or with any problems.

[pwdunmore]

No difference... if your engine calls for regular grade gas it's what it runs best on... this has been threaded to death

[Tokic_o]

your car runs on 87...just use 87 and save a few bucks.

[Vgandoza]

Thanks for the comments

[loki]

you've been spending 14 cents per litre more than you had to for an entire year

should have been running 87 octane this whole time.

If I spend an average of $40 a week on gas.... let's do some math.

Averaging at $1.20/l That's $2496
At premium you spent $2828.

Our cars will simply "learn" to use the 91 fuel as it would the 87 fuel because that's the way it's programmed.

Did you see improved performance on your ride with 91? Horsepower, acceleration, torque, whp?

How would he know? He hasn't used 87 in over a year!

Gas mileage sucks with 91 for me 30kms for one bar. Well I've been reading a lot of mazda 3s have bad fuel milage

so... roughly 300km per tank? Are your feet heavy?

[Vgandoza]

[Vgandoza]

That's not very good man. There have to be other factors causing only 350/tank for you.

[Mazdy]

Lol this is a joke...

Maybe he have a speed engine :chuckle

[pwdunmore]

speed mileage isn't even that bad lol... you should be getting at least 400km otherwise your car sucks gas worse then a turbo

[VertigoM]

Yes that's very bad mileage. Even on my Speed3 I'm getting between 9.5 to 10.5 liters/100km.

But you forgot to read the part where it says Mazda 3's use 87 octane

[Jackal]

I think most GXs are getting 500-600 from what I've read (and using 87).

[zzz3]

you should be getting over 600km easy with a GX. i get 700km~...

Rotary engine swap?

[Lockdown]

Maybe there is an extra 1000lbs in the trunk.

[silverstarmazda]

heard you can run a higher octane to clean things up? i dunno if its true or not...can someone jump in on this?

[Thrizzl3]

around 350. no my feet arent heavy

my automatic GX with tiptronic, intake, HKS exhaust and 18" tenzos got 600kms to a tank..and i hammered it everywhere.

the only thing that it will be cleaning up is your wallet.

naw, just throw in some STP into the fuel tank from time to time if you wanna achieve that

[Impressive]

epic troll.

wtf thats insane man. I get like $500km MAX and thats with like all hwy driving...

[Booter22]

why you even waste the money on 91 when your not going to get any gains from it. just use regular. good old 87, and maybe the odd 94 fill up if you must.

[VertigoM]

You make money while you drive? That's amazing :P
