Asked by for the 2008 Nissan Armada
Why waste your money on synthetic?....all the years I've seen people use it ...mostly because it makes it easier to excuse neglecting oil changes ya for 20,000 miles.(JUST MY OPINION OF WHAT I"VE SEEN IN THE BUSINESS)synth , or reg. if it's neglected's neglected.....won't last any longer .
