What RPM range do you drive???

[Flavor 987S]

After fully warmed up, my car see all the gears and all the rev ranges. Been this way for over 55,000 miles and 8 driving seasons now. Rarely take to redline, but with in 500-1,000 RPM of that all-day-long.

Highway cruising......6th gear.....65-70 MPH.

I was curious about this topic as well. For me, on local streets, I try to keep the RPM between 3k and 4k because of the IMSB. On the freeway, I'm usually in 5th gear cruising at 60-75 mph, which results in 2500 to 3000 RPM. I feel 3000-ish is a good balance between fuel efficiency, torque, etc., but I'm really annoyed by the vibration at 3200 RPM.

3K and above.

I used to be very mindful of the fuel economy for a brief period of time where I was having to make 100 mile round trips every few days. I analyzed 3K and above driving and 2500 -3000 RPM driving.
The final analysis was that it saved me little in the bigger picture of engine care/longevity.
Porsches have a near fail safe way of guaranteeing that what you think you're saving here ends up costing you more elsewhere. I concluded its best to save money elsewhere in my finances.
