who is selling yamalube engine oil and yamaha precision blend the cheapest these days ? Mike R
Much, much has been the debate on Yamalube versus Pennzoil versus Royal Purple, versus every other lubricant out there. How does one really tell which one is better? Millage is one way that I know of, but each person's boat and throttle hand are different. Other than that, what is the determining factor in telling which oil is better? An engine teardown, and how often do we do that, unless the motor crapped out? And even then, it could be a mechanical issue, and not a lubricant issue...Just thought I'd throw this out there....
