oh I’m fully aware of that. That’s why I’m a frequent visitor of the above 4K curve. It’s a fun place to be ( a few seconds at a time that is).And the proof is in the pudding when it comes to better MPG. It is something that I can’t dispute.You do realize that using the 93-octane won’t give your more power unless you keep your engine running over 4,000 rpm all the time.
Here by releasing this official power curve on the 2.5T, Mazda wants to show “additional high-rpm performance is possible with higher octane”, and “to prevent unnecessary spending on premium fuel, both power ratings are published”.
