My car currently has about 42k miles on it. 9k of that being turbo'd (10-11 psi daily, and 16 psi max).
I used to use Mobil 1 Synthetic 5w30, but recently switched to M1 TDT 5w40 because of the recommendations here.
The oil tested was M1 TDT 5w40 (not 5w30 truck/suv listed in the analysis).
I'm a bit worried about the copper, but I'm pretty sure blackstone is correct that it is my air filter
because I havent cleaned/lubed it since day one, only because it really doesnt look that dirty.
Its the K&N cone filter, has anyone had problems with their K&N? I hear that they are great for flow,
but dont filter as well as they should.I think I might try something else probably AFE.
Also, my TBN is 4.6 and thats after driving super hard and boosting all the time. I knew I was going to sample my oil so I pushed
my car a bit harder than I usually do to really see if this oil can handle. How many more miles do you think I can add to my
future OCI's with a current TBN of 4.6 at 5k OCI?
...btw USPS Priority and Blackstone were super fast! I changed my oil on Friday, shipped it out on Saturday afternoon,
and I got the email from Blackstone Monday early afternoon!
