The main reason I used it this time was that it comes in a gallon jug.  My
motor takes 4 qts with a filter change.  My arms were full of other things
when I remembered I needed to change oil soon and I did recall that posting
about Zinc and flat lifters...dunno if that applies to an inlne motor...but
anyway....similar weight oil but it gives out 10-15 psi more oil
pressure..all else being the same.  Thought that might be of interest, I
know the WBX motors sometimes have issues with the OP going a little low at
idle.
