In real-world conditions, what would be the effect of changing the oil in my CRV's 1.5t's engine from the Honda-specified 0W-20 to a 0W-30?, specifically Mobil1 0W-30 AFE. This is an API Certified GF-6A oil. Assuming (dangerous, I know) that it doesn't meet Honda's requirements, would it still allow the engine to operate properly without voiding the warranty
