I've said it once and I'll say it again... just because all the manufacturers use M1 as factory fills does not AUTOMATICALLY mean it is the best oil for that application. More often than not, EM has the MONITARY RESOURCES to make it worth the manufacturers time to use/promote thier product. I'm not knocking M1 at all, but EM DEPENDS on these manufacturers as a part of their marketing. Look how often EM refers to thier factory fill list in their ads or responses to quality questions. That's their ace in the hole. And it's something that SOPUS/Ashland can't claim.
Still however, it doesn't say anything about THE PRODUCT ITSELF...
