1999 Chevy Express van, low miles, perfectly maintained, 5.7L. OM recommends 10W-30 for 0F and up, 5W-30 for all temps, severe cold, synthetic 5W-30 or 0W-30.
1. Oil pressure is instantaneous even with the few just above freezing morning temperatures I've had here. I expected higher pressure readings both cold and hot but the gauge reads the same.
2. Fuel economy went UP from 13.5 MPG to 16.6 MPG. My station could have switched from winter blend to summer but have not confirmed nor do I think the attendant would even know.
3. No loss of power, strange noises or other maladies I read here on BITOG that might happen.
Why? Because I had a gift card and it didn't cost me anything so I figure I would drain it if there was problems. Also, for pretty much every application that calls for a 5W-30 in NA, the M1 site recommends 0w-40 (which is named "Protection Formula") in Europe, including my van. I will leave it in for my typical interval. That means I will drain it in late October.
