Used Oil Analysis of CAMRY'S Pennzoil Platinum 5w-30 after 4,920 miles

About 7 months ago, I mailed to Blackstone Labs a used motor oil sample that came out of my oil pan's drain plug when I did an oil change. Here are the results of the UOA (used oil analysis). OCI means Oil Change Interval. PP means Pennzoil Platinum, a synthetic oil (Group III anyway). 6-month OCI (from May 16 to November 12, 2008). Toyota OEM air and oil filters (Denso 90915-YZZF1). 19,620 total car miles. This was my second consecutive fill with PP 5w-30 (API SM & GF-4). I had previously used Mobil 1 and Valvoline Conventional. Always gentle driving on roads in Columbia, Missouri and St. Louis. Special Notes: The first 3,200 miles of this approximate 5,000-mile OCI was exclusive city driving with most trips averaging somewhere between 15 miles and 30 miles (all city, again). The next 1,700 miles of this OCI was a 50/50 mix of city and highway. On the actual day of the oil change, just before changing the oil, I drove the car about 30 miles on the highway, then let it idle 15 minutes while I brought out the ramps and other equipment. Although my manual calls for 4 quarts of oil when changing the oil and oil filter, I always put in 4.25 quarts. This is Toyota's 2.4L 2AZ-FE engine, an inline 4 cylinder. Blackstone-Labs results: Miles on oil: 4,920 Miles on engine: 19,610 Sample date: 11/12/2008 ; Report date: 11/24/2008 Makeup oil added: 0 [First number = my sample's results] , [Second number = Universal Averages for this engine] Aluminum 3 , 3 Chromium 0 , 0 Iron 7 , 10 Copper 1 , 2 Lead 3 , 2 Tin 0 , 1 Molybdenum 53 , 90 Nickel 0 , 0 Manganese 0 , 0 Silver 0 , 0 Titanium 0 , 0 --------- Potassium 2 , 1 Boron 28 , 39 Silicon 17 , 17 Sodium 4 , 14 --------- Calcium 2795 , 2347 Magnesium 15 , 121 Phosphorous 714 , 719 Zinc 860 , 853 Barium 1 , 0 MY RESULTS // VALUES SHOULD BE SUS Viscosity @ 210* F = 59.3 // 56 - 63 cSt Viscosity @ 100* C = 10.03 // 9.1 - 11.3 Flashpoint in * F = 400 // > 365 Fuel % is < 0.5 // < 2.0 Antifreeze % = 0.0 // 0.0 Water % = 0.0...

ANY decent synthetic oil will do THAT. No need for a UOA unless you're interested in wear metals too.
