Yes but that is almost certainly 30, not 30W.
And this statement:
is just silly. Oil specifications are not like brands of beer. Manufacturers make oil recommendations based on the characteristics of the engine and the oil, using the best information available at the time the recommendation was made. If you have a bolt with a 5/8 head, and your personal preference is to use an 11/16 wrench, it might remove the bolt without rounding the corners off. But that doesn't make it the right wrench.Rudi wrote:So it pretty much becomes a personal preference as to which grade you use in your Cub.
Don't blow off "W" as a typo. The original question was specific to winter oil selection. That is what the "W" is all about. Like I already said, if you don't keep your tractor in a heated building and need to start it in the winter, you better use something with a "W" rating.
