2016 GS350 2,838 miles Pennzoil Ultra Pure Plus 5W30

[thenewguy]

Mostly all stop and go in NYC. 26 weeks. April-Oct. Fram Ultra. Driven hard.
5 mile, 20 minute commute 2x daily.
Previous report on 4/9/22 was winter months on Mobil 1 AFE 0w20.
This one was PUPPP 5W30 for summer.
Current fill is Mobile AFE 0w30 due to fuel dilution that occurred with AFE 0w20.

They haven’t called it Pure Plus in a long time.

This is a case for oil grade/type not effecting wear rates. Two different brands, significantly different viscosities, and exactly the same wear rates over similar miles.

Such a short OCI, even if over 6 months, does not really tell me anything. Why not stretch it out to a year?

2,800 miles? Such a waste.

20 minutes to go 5 miles two times a day??? Sounds like some SEVERE DUTY if there ever was one.

If the owner wants to keep this engine @ 100% then 3,000 mile oil changes can’t be argued. Nothing wasteful about sending lightly used Synthetic oil to the recycler. It will clean up the tank and pipes along the way

There was a huge drop in flashpoint and viscosity in the previous sample on Mobil1 AFE 0w20 which was even shorter in mileage, but also 6 months. I was planning on annual oil changes on this car given the mileage, but I'm glad I sampled it at 6 months. Although this sample on Pennzoil was much better in fuel dilution, I will keep it at 6 months unless my driving habits change.
