Hello all. I have been using Shell Rotella T6 5W-40 for a while now and only now considered changing to the 15W-40 weight. I know OEM Kawasaki oil is 10W-40 but Shell doesn't make T6 in that weight. Would there be any benefits or need to use one weight over the other? I live in California and...
I understand the desire to use a quality, yet inexpensive oil.
I suggest Mobil 1, 10W-40 Racing 4t. Available at WalMart. It is about the most robust and shear stable oil around. It is every bit as good and shear stable as the even more expensive Motul/Amsoil products.
CCS test and 40C start up flow test are important tools to know about
your oil because roughly 60% of total engine wear occurs during cold
start up conditions before oil can circulate through the engine...
At start up temp of 40C 212F 40 grades are ranked by their cSt flow
rates from the quickest 80 cSt to slowest 165 cSt...
I am in Michigan so it would probably always be 60 degrees or at least 50. I am concerned about shear being as the oil is shared with the trans.Some info has said the 15w doesnt shear as bad.

All oils will show some degree of shear during their service but
Blackstone's used oil report data has affirmed there are no reason to
fear the shear because as our oil shears flow increases without the
dreaded increase in wear... our oil serves as a wall of protection only
when it is constantly FLOWING between moving parts...
I would go with the 5w40 if it were me. In fact I have used T6 5w40 in everything from thumpers like your 450 to a turbo hayabusa and most things in between. Mind you the formula has changed over the years so I’m not sure if it still applies.
Unless your getting it for less than the Mobil 1 that Cujet has stated I would probably just run that these days.
