I was watching a Amsoil video on Youtube, constantly comparing it to other synthetics. Old cars, new cars, the narrative was the same. I have no experiance of Amsoil, not avalible in South Africa.
My point is why all the drama of punting a product?
Synthetic oil change, once a year or 15 000km is more than sufficient, regardless of the product.
When i worked at a Vw dealer in the late nineties we were doing the same interval on normal 20w50 oil with no engine issues at all.
Even later on at a Mazda dealer, 10 000km or once a year on normal Castrol GTD .
