Being getting 1L jugs on sale is practically never, I will be picking up 2 5L jugs of the Pennzoil Ultra Platinum Synthetic. Over a dozen videos with test results rated it higher then the Mobil 1, which had lower scores. Even the additive pack is a lot less in the Mobil 1. Being the two brands are priced the same on sale, I have no reservations about switching over.
Watching videos on YouTube to gather useful information on oils is not the way to go. In the end, it's your money and time do as you wish.
