Oil brand is Chevron Supreme 10w-30 dino, SM rated. My comment to Blackstone was that this was a "run-of-the-mill" OCI.
85% highway / 15% city driving. The engine is fairly modified and sees a lot of spirited driving. Used a "Made in Germany" Bosch filter, standard size for this application. Other than that, nothing worth noting about this interval.
Going back, previous oils used (shown on Blackstone report), in order were Motorcraft CJ rated 10w-30, then Citgo Syn-Blend SN rated 5w-30, first shown on report was Trop-Artic 10w-30 SM.
