My local Walmarts just got this a few weeks back.
Apparently, this oil has some sort of properties that make it cling to the engine more than other oil so not all of it drains back into the pan. So, with that in mind has anyone here tried using it? I imagine that if someone's using it and wants to then clean out the engine they'd need to switch to a non-Magnatec oil for one or two quick changes, but beside that I don't see a reason to not at least try the oil. If it works as advertised and is coupled with an oil pan heater as I'm sure many Ecomodders have and it should reduce engine wear by a large percentage.
