I used to think that carburetor equipped car motors would run run longer and smoother if the bulk of their miles were highway driven at the speed limit. I think that's probably still true, to a certain extent, but I'm not sure it makes much difference with fuel injected, newer vehicles?
I drive about 20 miles to work/home every day, round trip. It takes me about 20-25 minutes to get to work, and my temperature gauge shows that my motor has easily been running at normal temperature. My motor averages at about 2200 RPMs as I make my way down the boulevards, surface streets, etc. When I was actually driving today on the freeway, I noticed my motor runs at about the same RPMs at freeway speeds, which got me wondering...
Does it make any difference to my motor life that I'm driving on surface streets -vs- freeway given that my RPM range is pretty much the same? How about the rest of the vehicle?
