Oil Weight?? New Katech Oil Pump
I have a 2018 ZL1 with a new Katech oil pump installed. Should I change the recommended oil weight?
I was told to run 10w 30 |

We recommend the updated 0W40 spec oil in most stock bottom end builds.

Jannetty Racing recommended 10w 30 with the new Katech pump. I have no mods at all. Everything else is stock
So Katech Mike,, 0w 40 for everyday driving ??? |

During these Winter months when I am not driving the ZLE as much as I like and since I am not tracking the car until Feb/March... I switched back to the Amsoil 0W-40 Powersports Formula. This oil gives better internal coating during downtimes, sitting in the garage but also clings to the metal parts so when I do a cold-start, my internals are protected not only against wear but corrosion!!

IMO Changing weights within the range of 0w-40 and 15w-50 wont hurt so long you are sticking to full synthetic. See the chart below. I run a 5w-50 Supercar now, with my remote oil cooler, but ran the 0w-40 supercar before then.
