Blackstone Labs Oil Test - My Engine is Happy

TL;DR - I had my first oil analysis done, and with 235K miles on the Tacoma, it came back great. I've sort of postponed getting a Blackstone Labs oil analysis, since I was worried about what it would say. For the first 16 years that I owned the Tacoma, I probably only got 4-5 oil changes - though, to be fair, I only drove the Tacoma a sum total of 40K miles in that time. Since then, I've put quite a few dirt miles on the truck, and since 2016 I've been using an aFE air filter - something that…

At first, I thought it might just be water from a puddle, but eventually I was convinced it was some sort of oil-based substance. My guess was that it was one of either power steering fluid or A/C oil from the…
