I don't mind changing oil for my 2 kids and their spouses plus my own truck, but I refuse to buy 200-300 liters of synthetic oil plus filters a year.
So there has to be a viable cost effective alternative for 3 seasons of the year when cold start performance is not a concern.
I found 5W30 conventional engine oils a disaster, so for 3 months of the year I'm stuck using synthetics.
The rest of the year, it's 10W30 HDEO, 15W40, SAE30 or SAE40. Those 4 grades go in everything, sometimes some of each to empty a few pails into one.
I own a socket set if I have to change out an engine or transmission, but I hate chasing engine lights, 02 and N0x sensors.
I don't want to start replacing TWCs or DPFs on a 5 year old car or truck for a few dollars in fuel that thin engine oil claim to save.
I'll just do what works for me and leave 0W20 a mystery.
You are going to run 15w40, SAE30W or SAE40W in your new Silverado... in Canada?.......... hahahahaha
These ain't your grampy and daddy's Chevys anymore. You might freak-out when you open the hood.
