Engine is the 1GR-FE 4.0L V6, 209K miles, ~30K miles since I replaced the timing chains, sprockets, guides, and tensioners last year (see wear metals increase at the subsequent 184K lab test) due to original owner poor oil change habits and a chronic P0016 error code caused by the elongated main chain.
Oil was Valvoline Synthetic High Mileage w/ MaxLife 5W-30 D1G2 label, the new jug cap design. Current fill is the 10W-30 version, no D1G2.
I've skipped a few OCIs with Blackstone as shown in the history. Fills since the 178K mile oil change were Pennz Platinum-HM 5W-30 D1G2. I liked what I saw of Valvoline's new additive package now including moly, figured I'd give it a try. Not disappointed. Early OCI due to upcoming series of weekend road trips for kid soccer.
