2005 Mazda rx-8 GAS!!!
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.

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)

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

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.
