89 should be fine. I believe the compression on these engines wasn't really high like the early 350s, so you should run fine on mid-grade.

the best fuel to use is PREMIUM fuel--93 octane--for the best performance and fuel mileage. You can use 89 but it will not perform to the best of its ability no matter what anyone else thinks or says. I have performed quite a bit of in-depth comparisons and now only use premium in mine. The cost difference is not worth the difference in performance.

How about using regular grade gasoline and adding a octane booster product for each tank? I did this with my 2000 740iL BMW and the pings went away with a during acceleration. dmajor
