I have a GMC Sierra Denali 6.2L that I only drive on weekends. ( drive a work truck M-F). I use Mobil 1 oil and my last oil change was back in April of this year. The oil life indicator says I have 63% life on the oil. Should I change the oil since it was last changed back in April? It’s the whole mileage OR so many months thing that has me wondering? Thanks for the advice
