Pennzoil Platinum SM Synthetic 5w-20
03 Honda Accord EX, manual 5 speed with 2.4L 4 cylinders VTEC DOHC engine.
BlackStone Labs.
Oil had 7,985 miles, 35 weeks, 228 miles/week
Makeup oil: 0.
Car had 50,770 miles, 2 years and 8 months.
Honda recommends 5w-20 oil at 10k miles or 1 year for "normal" driving and at 5k miles or 6 months for "severe" driving for my 4 cylinders engine. My driving is stilled considered "normal" by Honda's definition even with me driving less miles and a few short mileage trips.
VOAs
Pennzoil Dino 5w20 VOA, dated Januarys 2003.
M1 0w20 VOA, dated April 2003.
Pennzoil Synthetic SL 5w20 VOA, dated June 2003.
Pennzoil Platinum 5w20 UOA , dated June 2005.
UOAs
Pennzoil Dino 5w20 UOA with 6.8k miles on oil, dated Oct 2003.
M1 0w20 UOA with 7k miles on oil dated Jan 2004.
M1 0w20 UOA with 7.6k miles on oil dated Apr 2004.
Pennzoil Dino 5w20 UOA with 7.2k miles on oil dated Sep 2004.
Pennzoil SL Synthetic with 6.5k miles on oil dated Apr 2005.
Right numbers are this Pennzoil Platinum 5w20 UOA.
My observations are:
1. Excellent UOA.
2. Wear metals are not much different between my dino and synthetic UOAs.
3. My fuel dilution is increasing.
About two days a week I only drive 2.5 miles twice a day. This must be causing my fuel dilution. Other days I drive a lot longer.
I'm thinking of going back to dino oil and OCI of around 6k miles.
All comments are welcome. Thanks.
VOAs Pennzoil Platinum is different lab.
Air filter was change to a STP SA9564 filter at 28,641 miles,.
TBN of Pennzoil dino VOA may be old method.
Honda oil filters were Honda's USA (Feltell) larger 80mm diameter oil filter, P/N 15400-P0H-305
