I was told to go that heavy by someone that knew I was running the tapered, So I will try it. He is also pretty knowledgeable unless he popped off and wasn't thinking. I have been reading about the tapered and how a thinner oil packs faster than a heavier oil will with the more surface area. Forgot where I read it probably on RCtech somewhere. I'll probably go lower after I run a few. Thanks for the feed back!
