89 Octane - Better Idle

etcthorne · 12-01-2007, 12:09 PM

There are a lot of possibilities here - winter blend gas at the stations, etc..., but I put 89 in the tank at last fillup just for giggles, and I swear the car idles smoother. Not that it idled all that roughly in the first place, but it's very noticeable. Same station I always fill up at too. Has anyone noticed a difference in idle when using higher octane?

Sorry I didn't mention that - I don't remember. The station changed ownership about a year ago... I'll be going by there again today and I'll post the name of the station then.
