Not enough to make any real difference. As others have said, thicker oil will warm-up slightly faster with all other factors held constant. If you want your oil to warm-up a little faster, then start driving it sooner than later after a cold start-up.Are there any write-ups on the difference of time, or lack of difference, it takes for different viscosity oils to get up to operating temperature? My search wasn't very successful. Thanks.
