Yeah I wasn't happy to see the Pennzoil changes.

It is funny to see Nissan is going with 5w30 now that 0w20 synthetic base fluid is becoming scarce, it will likely be a short-term change just based on supply dynamics from the Middle East. One reason I may eventually stick with Amsoil, these big oil companies always mess around with their formulas and good formulas get watered down over time, Amsoil only seems to get better.
Redline too! Even with the ownership change I'm glad to see Redline hasn't degraded their product.

Ive been using Mobil1 5w30 Extended Protection since its first break in oil. And for over 30 yrs, never had issues with it. Whether I buy Amsoil, Motul, or OTC, I change my oil every 3k miles.

Next oil change, I will be switching to Mobil1 5w40 Euro.
I have also landed on M1 5W-40. I'm changing the oil more frequently than 3000 miles however due to track use.
