See below for a recent UOA from our 2004 Lexus RX330. SUV has 221,500 miles on it and this interval had 4,105 miles.
I mix my own oil and this run was 3 qts of Pennzoil Platinum High Mileage, 2 qts of Pennzoil High Mileage (both 5W30) and 4 ounces of Tufoil.
Filter is a Fram Ultra with a filter change every other oil change interval.
BTW, I broke the back bolt on the air filter box between this interval and the previous one ... I may need to repair that.
