i just got an 05 rx8, and i was wondering what kind of gas. My dad workds for a dealereship and they said that you can have 87 gas??? I thought you are only suppose to use like 89( premium or unleaded) but they kept on saying they have been using 87. Im pretty sure that you can only use unleaded... ANYONE HAVE A GOOD ANSWER PLEASE!!!!

Thank you.

 

simple answer:
R.T.F.M.

 

 

Amen

 

91+

Read the manual.

You can use lower than 91 if you are somewhere that premium gas is unavailable but it isn't recommended by mazda.



(cue the same 5 people that say running 87 is ok)

 

unique: I noticed your user title says turbo_8.
which turbo kit do you have installed?

 

And where exactly can you buy leaded gas?

 

I use regular, and no mazda does not say to use anything but Premium. If you are turbo then thats another story I guess.

 

Can I have the two minutes of my life back...........please!

 

^+1

I'm starting to see why members get frustrated with some of these topics....

 

Mazda does not say not to use diesel, so try that * this posstee claims no responsibility if the op uses diesel *

 

Don't spread fals information... I have a sticker inside my fuel lid that reads like this:
Unleaded only.
95RON min.

 

OP I highly recommend natural gas. Now go read the manual and stop wasting our time with these stupid *** questions.

 

Mazda kinda did say to use 91+.

 

E85 dude save some cash!

 

or blow the engine up, lol.

 

wow. Seriously some people does not deserve to live

 

Lol its a joke, if the lid sais that then put that in

 

94 Octane Ah yeeeeee. Even though its designed for 91 Next time search for the answwer

 

donno how you guys measure in Canada. different standard has different numbers even for same gas.

 

Thats pretty interesting Jason, never knew about that. Thanks for the info.

 

Well Mazda does not say NOT to use water or butane or propane or pee or beer or...well you can get the picture.
We are talking about grade of gasoline,. paragraph period.
87 is fine
as long as you do not drive it like you stole it.
I only use 87 and sometimes pre mix
Have a stick 06 since Sept 07 and no problems (crossing my fingers)

 

stop being cheap and spend the whopping 20 cents more a gallon for premium. If a few bucks more is too much then just sell your rx8 to someone who will take care of it. This ain't no gay *** 35 mpg civic

 

Stop being profligate.

 

Read MY manual (2004).

That's Mazda saying it's ok. 7 years and 50,000 miles later, about 49,000 of them on 87 octane.
