Pretty impressed with the oil and how clean the engine is after 80K miles. Miles are mostly highway though, I do 80 miles round trip daily frown

welcome Nice UOA. Just look at those additive numbers, PYB sure is a great conventional oil. thumbsup

PYB is good stuff and has to be in the running for the best conventional oil available. Your TBN had to be sky high for Blackstone to recommend the bump to 7000 OCI. Thanks for posting.

Thanks. I will probably push it to 6K and send another UOA.

The past 5 oil changes were done by me at the house and I have always used PYB. Prior to that it was done at the dealership because they had super low prices. I assume they use Subaru branded over there whistle I had a Honda Accord with 200K+ miles and all it had was PYB. Why change a good thing? smile

Not yet. Hopefully never have to do it until I switch to a WRX STi smile

I do 10k on PYB and lots of other new Pentastar 3.6 people follwing the OLM are too without realizing. PYB is a fantastic oil.

The shot of moly is nice! I would like to know the TBN of this sample, tho. I wonder if you can call to have Blackstone run what is left of the sample for $10 more? shrug Good 'ole PYB! +1

Nice. Use Pennzoil 10w30 or Pennzoil High Mileage 5w30 for better shear stability for longer duration. Pennzoil High Mileage is probably the best value in motor oil at $17 a jug and is non-Resource Conserving and a syn blend.
