I think the mystery about using a lower octane gasoline came from 2-stroke engines. In a 2-stroke you get better performance from a lower octane gasoline, since the rotary is compared alot to the 2-stroke that MAY be where the myth came from. The big differences between the two (and the reason you should use higher octane) Is that Pre-detination on a 2 stroke is not really a big deal, happens all the time and the engine is fine. If you pre-detinate a rotary you basically have to have the engine rebuilt (ie blowing the apex seals) Lower octane fuel can detonate at lower pressure than a higher octane fuel. Therefore there is a lower chance of pre-detonation on a higher octane fuel than on a lower octane fuel. I am sure that 87 octane will be fine in the 8, however a 20cent/gallon engine insurance policy is what I will be using.

Originally posted by ACRX8 You bring up a good point about the tires! The 18 on the RX-8 will cost ?? $$ US?? S03 - PP $187 RE040 - $223 Pilot Sport- $251 :eek: Pirelli PZero - $194 ContiSportContact - $126 I think for anyone with heavy foot and propensity to drive lots and hard while lapping/autoxing the tire costs will be enormous... The extra fuel cost for premium is negligeable, especially in North America.. |
do we know for sure yet if the reo40's are standard fit?
|
I'm not sure.. but probably.. especially since there is no spare, correct? The RE040's come with the runflat option.. I will still lobby my dealer for a switch to S03's.
Btw, the winter tires will not be so cheap either. For the 225/50/17 size it's anywhere from $133US to $168. Ouch. Everyone loves the looks of big wheels/rotors until it's time for new 18" tires.. :( |
Already looked into that as well. Thankfully, Bridgestone makes their excellent winter Blizacks in 225/45 18 size. Perfect...:D
|
uhh, i was just looking at the bridgestone website and they don't list the RE040 in the 225/45r18 size:confused:
edit: oh and on topic, i think you should use whatever fuel grade the owners manual says. |
Yeah I seem to remeber not seeing them either.. But they are on the Tire Rack. Shrug. I'd rather have the S03's or Pilot Sports any day...
|
OK:eek:
I just put 4 60K mile all season tires on my Mazda 626 for a total of $180.00. The wife is not going to like this! |
Will 17" rims fit?
Do you know what the bolt pattern and offset is for the stock 18's?
I have a set of 17" snow tires for my current car (225/45/17) and would like to use them on the RX-8 if i get it. I think it will be much cheaper to get a set of 17" rims for the snows rather than get 18" snow tires (if they even make them). |
Higher Octane
I haven't got all the mechanical knowledge that a lot of people here have, but... I've currently got a 2001 Honda Civic. The manual requires 87 Octane. Maybe it's just me, but I like to spoil my girl... so I give her 89. For that extra $.10 I get better performance, better gas milage, and satisfaction that my engine is going to last a wee bit more than I'll actually have the car.
And it's just preparing me for the extra $.10 that I'll have to shell out once I get my 8 (so it's not so much of a "sticker-shock") Strider- |

I will definitely look into dedicated 17" steelies/tires for the winter. The tire savings will pay for the steelies and the oem rims will not be ruined by the salt. |
