While we're here, what exactly are you hoping to accomplish with a short flush with cheap oil that a normal OCI with a "better" oil won't accomplish?
The oil I want to use is Zepro with moly. I have Castrol Edge, which is a pretty good oil and recommended by Mazda. I was thinking about for the first oil change in my 2019 Miata I would try that to get all the break in nasties. Install the new filter before the flush. Since I am installing a Fumoto drain valve I can run a clean tube in to the jug and drain it in there. Fill the jug to top with oil and let any containment settle for next oil change. Kinda anal but like a mouthwash for my engine. While the car is on the jack stand should not take too long.
At what vehicle mileage will that first oil change be at?
If you are changing that new oil at 1-2K, then there's no need for a flush soon after.
