These folks are basically telling on themselves by implying they’d run the Amsoil for the same length of time as a OTS WalMart synthetic.
Because, if price is the most important factor, they couldn’t possibly be running the oil longer and claiming it’s more expensive when the cost becomes much more negligible if running the oil 2x as long as the floor; let alone if able to run it up to 3x as long.
So, of course it makes no sense to buy boutique if you don’t even understand what you are buying compared to have always used. And, if you believe you understand the quality/capability difference of a boutique designed for extended drain intervals…why isn’t the actual out of pocket cost figured in?
Just saying
