The user's manual says the 9-5 will run just fine with lower octane fuel, but also says it was designed to run on higher octane. My 2001 V6 seems to run well on the lower octane. But I was wondering about engine wear--does the octane level affect it? The dealer just had to replace the turbo unit under warranty with 40,000 miles.
