This is my second UOA for this motor. The first UOA with Mobil 1 5w30 is posted here.
Due to the good reviews for NAPA Synthetic, I decided to give it a try. A great value when it's on sale.
Anyhow, the main differences from the last UOA with Mobil 1 5w30...
1. More hiway driving (70% vs 50% for the last UOA).
2. Shorter time in use (20 months vs 32 months).
3. More use in colder temps and early morning cold-starts.
4. MPG went up... due to more hiway driving.
Filtration: Air filter is unchanged, 20,000 miles old at the time of this sample. Oil filter is new. Both made by Wix.
NOTE: Sodium is high in VOA of NAPA Synthetic... as documented here.
