short drive to work
 

I have an 01 lb7 and I bought it for my last job cause I drove state to state and it worked great. That job went under and now my new job is 15-20 min from my house and so my diesel dose not get very hot and i know that's not good for diesels. besides buying another rig cause i cant afford that any advice especially since winter is on its way.

Take it out for a long drive every once and a while.
