I think it heats up so fast because of the catalytic converters. It's been running a tad warm so I might go to 5w20. Heated steering wheel is hottttt! I never turn it on until it's under 20f.
It is. Especially when the putz in the Camry hits you head on. For more fun just unbuckle your lap belt and draw a target on the inside of the windshield.
