Aw no need to be shy.. I'm not so passionate about oil types, though I do like the synthetics. Been thinking about switching to Valvoline Synpower as well for all my gear oils, mainly because of cost. The comparative graphs that Amsoil has all over the place proving that Amsoil is best shows Valvoline and M1 fairly close on all the tests.. I suspect the difference is negligible for my application.
However, I have left the sales manager at Siegel Oil in Denver a voice mail inquiring about group buy options, will keep you posted. I know I'm not the only one who likes the 0w40..
