Anyone run Royal purple?

[DISCOLEG]

All I know is my 2.7 Ecoboost on 2015 F150 will run 5-10°F cooler on Mobil 1 fully synthetic oil than factory oil blend.

Running Royal Purple in my 2019 Ranger Lariat FX4 (40k), and just hit 7k on our Bronco Sport Badlands.

I was partial to Pennzoil myself.

Wally-world Super Tech for me. 5qt jugs of full synthetic cost under $20. Last time I checked Conoco was Super Tech's wholesale supplier.
