Would it make sense to switch oils depending on the season? Am in Chicago so winters get pretty cold, but in the summer its hot and I track quite a bit...also, is there any risk in preventative switching out OEM for OEM of the bearings?? Am worried I've had no problems, replace the bearings, and the new ones don't match as well or they create a clearance issue where one never existed before...does that make sense? Also, haven't heard enough about the statistical probability of these events and how much tech and engineering improves and that clearances may or may not be changing over time...I plan on doing a winter refresh with the car and am just running down the checklist and looks like this will be added...the beauty of science and engineering is that almost nothing is set in stone (thinking larger concepts, not math) , just greater degrees of understanding...thanks for continuing to add to that level of understanding to all
