Hell, even the Maintenance Kit offered by Cub Cadet for Kawasaki engines comes with 10W-30!

Yet 10W-40 is the recommended viscosity (presumably due to its wider range of ambient temps). So, it seems you recommend going with the 10W-40 despite its (higher) cost and its lack of local availability?

I'm not trying to ask a loaded question although it's certainly coming across that way! I'm just trying to make sense of why Kawasaki recommends 10W-40, yet that viscosity is hardly stocked locally, and when it is, it's only the Kawasaki brand. Not to mention that Cub Cadet themselves puts 10W-30 in their Kawasaki maintenance kit.

I think I'm overthinking this way too much and should just use 10W-30. But then I'll wonder if I'm hurting my engine when the temp gets above 90 degrees. But then, given how 10W-30 is the most available, I won't be the only one!

Thanks!

I'd stay with the 10W-40 But It doesn't Matter which Manufacturers 10W-40 you use
