Extended freeway driving?
I've got a question for anyone who has a good answer 
....
At least once a month (sometimes more) I drive 600 miles of freeway at a pretty consistent 80mph. As we know this is a 4 cylinder engine so my rev's are around 3,400-3,600 at 80mph. My drive takes about 4-5 hours. Is this consistent high-revving bad for the engine? I know its meant to drive at high rpms for track use, but is it okay to sit at 3,500 rpm for like a solid hour?

dude you should be driving a prius or something with better mileage. your gas bill and tire bill must be incredible!

lol... you're like asking if i breathe too much today am i going to have problems?
seriously i dont see any car will break on just measely cruising for a few more hours.. heck i drive up and down in Cali for 9-12 hours each trip non stop except for gas. don't worry too much dude.. except maybe you need to worry about nails on the road.

80mph at 2750rpm would be dope =)
