I have been keeping highway speeds down to 55mph just to help reduce the rpms a tad bit. I'm not really in a hurry to get anywhere and if I could slow down more without being ran over on the highway I would. Here in PA most 4 lane highway speed limits are 55 mph, most folks do 70 or more with no second thought.
I guess it's just me, but I would hope the folks at Mitsubishi made this engine to run at those rpms. I just see in my mind piston rings screaming for help.
Can anyone help calm my fears? Am I the only one? This may be partially due to being a big motor guy owning his first small motor car?
I think you can relax. I had a 1987 Dodge Colt with a 4 speed than turned 3500rpm at 60 mph. I sold it with over 200k miles. Still didn't burn any oil. Mitsubishi makes a excellent small motor. With a double over head cam multi-valve engine you shouldn't worry. You should be able to run this motor continously at these rpm's without fear of shortening the lifespan of the motor.
