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). 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 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 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

TBN 4.7
TAN 0.9
Built_Well's Note: The TAN and the TBN readings cost an extra $10 each, and you gotta request them at Blackstone if you want them. I forgot to request the TAN, but I emailed them a day after receiving my results, and they pulled my oil sample and ran the TAN. I was happy that they didn't immediately throw away my oil sample after running the standard tests the day before. I don't know how long they keep the oil samples, though.
Anyway, I wanted a TAN (acid) reading just for fun to compare it to RLI's Bio-Syn reading when I send the Bio-Syn 0w-30 to Blackstone in 6 months. The results above for the used Pennzoil Platinum 5w-30 oil happened during moderate temperatures and weather from May to November (mostly Summer and Fall). I think it'll be interesting to compare the nice weather PP results to the harsh weather Bio-Syn results (Winter).
