I have a 2004 GMC Yukon with 177,000 miles. No problems and not burning oil. currently running Mobil 1 5w30 with a Mobil 1 filter. Picked up a ton of Purolator classic filters and also have a number of Mobil 1 filters. current oil changes are 6,500-8,000. thinking about running 5-6,000 mile changes and using one of the two oils above and purolator classic.
thoughts? or should I stay with Mobil 1?
