2020 sr cold start rattle

Imo all the popular name brand synthetic motor oils are all top shelf, it just comes down to small differences in additive packages that make them up.

Ive been using mobil one oil and filter for the past year. Small improvement over the lower quality brands so it’s all I use. Doesn’t fix it though.

Truck seems to rattle less when it’s below freezing but it can still rattle regardless of temperature. Sometimes i get lucky and it won’t rattle for a few days or week bit alas, to bad the solution isn't as simple as using a better oil.

So far mine hasn’t done the cold start rattle and it has been minus 32 degrees Fahrenheit for the past week. It’s hasn’t done it for 9 days now. The oil brand difference fixed it for me as of now.
