The pick-up is a 2010, with 78,500 miles on it. The oil has been changed at 3,000 miles since new- an older owner such as myself. He always ran STP 5-30 since new with an STP filter. I suspect I will use Mobile 1 with a Fram Ultra filter when changing the oil. Thanks for your replies so far, does anyone know who makes the STP oil? It shouldn't hurt to go to synthetic at all.
