I currently do 5 miles one way too, no freeway, takes a bout 12 minutes. But the engine temp always get to 180 on the gauge when I get there, so I assume my engine is safe?

Hancock; You are correct. Now I don't wish to pass off my idiosyncrasies I've developed from my years of driving an shall we just say array of vehicles. This was crucial in older carbureted cars where chokes caused raw fuel etc in the oil pan. Current fuel injection has gone a long way to deal with the cold start issues. However the logic still continues that lots of freeway miles are much better than many short trips. Reason is systems haven't stabilized at "Normal" temps to cook off the contaminates that have condensed into oils, trans included, forming corrosive contaminates in the engine etc. 5 minute trips hardly recharge the battery from the start! Many opinions, mine included, but I try to drive no less than 20 min after normal temp achieved. SO get out there and paste a grin on your face a little longer! Oh the horrors!
LOL.
