Katech told me they can't tell a difference in the '19 and up pump
My ZL1 was built in October of 2016 and I took delivery in November 2016 so it's from the first production run. I switched over to Mobile 1 ESP 0W 40 in May of 2018 as soon I heard about the factory fill change for 2019.

You can all call me crazy, but I noticed a subtle improvement in my car's performance immediately upon changing to the 0W 40 weight oil. My car had a bit more pep and smoother acceleration. Nothing night or day but it was significant enough to notice. I would have never thought a slight change in oil viscosity would make a difference in performance but it did.

I know this is going to sound crazy but the change to 0W 40 oil is one of best mods done to my car.
