I made the decision to dive in to Amsoil and I will be striving to get a 7,500 mile OCI....or 8 months, which ever comes first. I am going to mix 3 quarts of 10w40 and 1 quart of 20w40. That will make an oil that is..... 12.5 w 42.50 I want a slightly heavier oil than 10w40, as it will be shearing (shared sump with tranny) and I want it to last the full expectation. Probably out in August, September or October, I will drain and do an OCI for your viewing pleasure. Either the Amsoil sticker will earn its place on my tank, or it will be removed!!! Any comments are welcome. For instance..... * What do you thing about mixing a soup? * For a bike that calls for a 3,500 mile OCI, do you think Amsoil can go 7,500 miles or so? * Can Amsoil pay for itself in motorcycles or will the lower OCI's simply cause it to be cost ineffective?
