I drive 35 miles to work. I go up a 6% grade on the way to work, but of course, go down it in the afternoon / early evening on the way home. It is about 5 miles long, drop from 2700 ft to 1200 ft of elevation.
I always use the engine to break. I set my cruise at 53, and let the transmission downshift to hold the speed (the speed limit is 55, but when I set the cruise at 55, the RPM's stay at or above 3500 rpms, and the oil runs 90 psi in pressure.
I grew up learning not to use the brakes when going down steep declines, but am I causing damage to the engine running 3400 rpms for 5 miles. Just asking opinions and will try and do a poll.
