It's now 3 days post switching to Mobil 1 0W40 and it seems to have made an improvement in smoothing cold-weather starts, which is what I was hoping for.
The engine warms up a touch faster and there is much less jerking/lurching in the lower gears prior to proper warm-up. (Sure, it might be placebo or the fact that new oil is being used, but I'm trying to be as objective as possible)
I'm thinking that this oil is a bit kinder/gentler for daily driving
