I've read a lot here, and I'm just seeking to understand, outside of wanting a long drain interval and using the engine in an ideal manner (no short trips, all highway), what is the use case for boutiques? I can see if you drive 20,000 miles a year, and you're not short tripping in the winter (when you'd presumably get fuel dilution which would make a boutique a waste), then doing one oil change a year with AMSOIL would make sense. You'd save money and time instead of doing 2-4 a year. (I also note that even AMSOIL doesn't fully prophylax against oil burning: example of a car burning on AMSOIL.)
But once you introduce severe service into the equation, is there still a use case? Fuel dilution will shorten the lives of even boutique oils.
You can clean engines with VRP.
You can get excellent wear protection with Euro-approved oils off the shelf at Walmart.
What am I missing?
