It's overpriced boutique oil imo.

Noticed a difference in mine just switching out the factory oil and replacing it with Pennzoil "Dino oil", also my mpg per liter has also gone down.

Once winter arrives, I will switch to Pennzoil Platinum, but if I don't notice anything noticeable with it as far as better gas mileage or a smoother/quieter running engine, then I will switch back to the Pennzoil "Dino" oil.
