#151
ok....I know someone stated somethin' about mixin' fuels in between fill ups, like 89 w/ 93 in the same tank, that navy dude is right, doesn't matter! and heres proof! --- http://www.globemegawheels.com/news/...utomotive.html should be some help to some of ya's...
I have this link somewhere else in this club, but w/e, here it is again!
as far as this thread goes, I could care less if it goes on forever, thats what its here for. we want to treat the 8's right! as far as stateing whats in the manual numerous times, thats NOT nessacary!!! geesh, once or twice is fine

Here in Spain I can only buy (unleaded types) 95 and 98. I use 95 without problems, although the car is very new (2000km). If anyone knows different....??????? Is the 89 or 87 octane which people talk about unleaded?? Should the car have unleaded or is regular ok??????? Should I try to find if there is 87 and whether it is unleaded????

Hey Paul,
I believe Europe measures Octane differently than US. I believe Europe uses RON method of measuring Octane. 87 US Octane is 91 RON Octane (reading from the US manual). I believe if you read more of this thread you will find more detail. If you agree with the discussion points in this thread where 87 Octane is OK, then 95 RON Octane should be just fine. We are all talking about unleaded fuel. In fact, I believe it is very difficult, if not impossible, to find leaded fuel in the US.

Many owners including myself, use 87 octane.
Our Rx8 expert mechanic here at the dealership who worked for Mazda and trained my Mazda in Japan, will tell you the same that 87 octane is all you need for the Renesis Engine.
Im not telling you to take my word for the hell of it, but there would be no reason for me to lie to you.
If you put 91+ , then so be it. But if a Rotary expert tells me that high octane fuel is not needed, then I'll take his word for it ..

I used 91 octane since I bought the car last December, after reading this thread I used 87 octane the last few tank fulls and averaged 2 mpg better than I have using the 91 octane! Strictly city stoplight to stoplight driving netted me 14 mpg using 91, the last few tanks of 87 averaged 17 mpg! I did not notice a reduction in power but the timing has to be affected by different octanes. The only time I notice power variations is during a big temperature change per say 50 degrees at night to near 80 during the day!
