In the manual, it says that the Celica should run on 91 or higher RON octane.
I was wondering if there's any benefit to running 98 RON (as per BP Ultimate) consistently, and most importantly, whether it has any side effects or detriments to the car in the long or short term? Sorry if this has been asked before, search didn't come up with much. --------------------  |

You wont notice a difference, the higher octane simply is used to fight off preignition. Everyone who notices a difference well, its psychological.

[right][snapback]243370[/snapback][/right] Actually, you can notice a slight difference, (in a GT or other engine with a higher compression ratio, an 8:1 low compression ST wont notice anything), the premium allows the computer to NOT retard the timing in response to the knock sensor, if you ever hear the pinging sound under load, you could benefit from a premium fuel, and I get approx 1.5mpg better on the premium over the lowest octane The U.S. uses RON + MON divided by 2, which is why our numbers are lower.
