I daily drive during the week the 97 in my sig to work 4 miles their and 4 miles back. Being the short distance I drive this truck daily im worried it may be doing it harm as it just barely gets to temp before Im to my destination and have to shut her down. It also doesnt get any use on the weekends either, Is their any special things I should be doing to extend my life with such use cycles? I already for sure plan to change oil and filter every 4k
