Quoting GreyWolf:Yes. Automotive oil probably isn't a wise choice.
As long as there isn't an EC in the bottom of the rating donut, it will work.
My question was:
Can somebody verify that a regular car engine oil of rating 10-40W or 20-50W (for hot weather climate like in TX) will work fine OR should I be looking for "motorcycle" 10-40W oil (if there is such a thing)???
