I just can't seem to break my Amsoil SS 0W-40 habit. I feel that I need the 0W where I live but also need the 40. I don't tow very often, and when I do the weight is only around 1,000#'s or so. But 99% of the time I carry a very heavy camper, around 3,700#'s, probably quite a bit more. I often drive in mountainous terrain and even though I am one, I don't drive like an old man.
So in a nutshell, I push my truck hard.
I am well aware of the drawbacks of using an oil with such a wide viscosity swing as the oil accumulates miles/time and shears. My strategy to mitigate this issue is to simply go no longer than 5,000 mile oci's. So far so good. My engine seems quiet (I really have nothing to compare it to).
The price of the HPL oils, especially when the shipping to my location is factored in, makes them a no go for me. At least at this time. If my engine was a ticker, or develops one, then sure; still a minuscule cost compared to an engine rebuild.
