How Much Time do you Spend on Oil Research/Analysis

[supton]

I do none. I buy boring cars that generally don't have any special requirements.

But I agonize over too many of the other details. Like tires. I've made spreadsheets comparing user reviews and other metrics.

I have no idea how much heavier it got in the longer runs, I've not done a UOA on it. I am speculating it's probably around 10cSt, not 12.

10 is not too bad

Hey, on this guy's Ram, it got to 9.87 after 12,000 miles. Not bad at all

1 year, almost 12k miles, and I was certainly not nice to it during that time (towing/hauling, driving like an insufferable donkey at 3am, y’know how it goes). But otherwise looks like a good report, truck now has HPL Supercar 0w30 in it, I’ll test that after a year for my own curiosity.

Maybe bad driving like short trips, fuel and water in the oil increase oxidation. In my case those won't exist, so my oxidation shouldn't be too much
