Just got 2004 F150. Kept my old '91 Ford Tempo. I drive each day only 2 blocks to work. The car then sits all day until I drive it 2 blocks back home. Over the years I have had to replace the muffler every 2 or 3 years and the battery more often because of this. My previous car died of a sludged up engine at 82000 miles. With the modern technology and oil is this still really hard on an engine and is it worth it to keep the old car just for the around town and drive the truck only on longer trips? I do tend to keep my vehicles 10 or
12 years.Thanks
