Safest cruising RPM
Just wondering what you guys think the safest, lowest cruising RPM is for the 5.0 with manual trans (light engine load, flat ground of course). I have 3.31's and hate being stuck in 5th gear between 45-55 over 2k rpm (kills my mpg). If I shift to 6th, I will be below 1500 rpm and that doesn't seem safe. I try to stay 1500 or higher.
For you automatic transmission owners, what is the lowest rpm it will cruise at in top gear, torque converter locked?

The 5.0 will lug the car around at 1K all day long without issue.
I always try to stay in 6th while cruising down the road.
It's also the only way to get any semblance of fuel economy.

Doesn't feel at all uncomfortable to me or the motor, run like that all the time.
And speed is just a downshift away, no biggie.

Then on the ramps I let it rev high while merging. Someone here said "Redline a day keeps the mechanics away."

2011 automatic with a 93 octane tune, cruising at highways speeds, the tach shows at the 2K mark. 3:31 rear gear, and the onboard MPG indicator shows a constant 23.6 range.

I have the V6.....I am getting on interstate usually about 26 to 27.....in town is about 22 to 23......6th gear I do not use until on the interstate above 60 mph. I try to keep my revs below the 2k range as much as possible......I shift alot in town since I don't use the interstate into work....so I normally don't get past 4th at all. My 14 is 3800 miles so far on it.

I wouldn't worry about hurting the engine, even at 1K RPM in 6th the engine doesn't really lug.
