2004 Lexus RX330, 5659mi, Pennzoil Platinum HM 5W30

[newtoncd8]

2004 Lexus RX330 AWD V6 with 245,459 miles. Pennzoil Platinum High Mileage, 4oz of Tufoil and 5,659 miles on this change.

Oil filter is 90915-YZZD3 (larger filter, 90915-YZZD1 is spec'd) and particle count is provided with ISO code 24/23/15.
--Interested in the discussion as to how this ISO code is the same as DuckRyder's Fram Ultra post (https://www.bobistheoilguy.com/foru...t-open-fram-xg7317-12-045-mi#Post4848992).
--Will put on a TG for a sample to compare filters and particle counts (that will be at least a year from now).

Air filter is OEM filter (I fixed the airbox from previous sample).

Side note, does it look like PPHM changed their forumula at all (i.e. magnesium, calcium)?

Any thoughts on a (possible) change of formula for PPHM? Except for 12/2006, all runs are Pennzoil products.

Likely it's their Dexos 1 Gen 2 formulation, I noticed the PPHM 5W-30 bottle I bought earlier this year had the D1G2 logo on it. May also be SN+ formulation. Either way, Ca drops and Mg increases.

wear metals are steady with the 'new' formula, good report but no improvements.
