The vehicle is 04 Chevy Silverado. The coolant temps reach operating temps as soon as I'm on the freeway, but I don't know what the oil temp is exactly as no oil temp gauge. My truck doesn't have OLM. Sometimes on weekends I drive a lot more, visit my parents 22 Miles away, go to the beach 36 miles away, etc. I'll prolly go Full Synthetic 5w30 OCI once a year or 5w30 conventional winter 6 months and conventional 10w30 summer 6 months. Thanks all
