I recently purchased a Hustler Super Z with a 25 HP Kaw. and would like to know what is the best oil to run it??? The manual is very vague about the weight to use etc. I would really appreciate any recommendations for the proper oil to run. I want to ensure I do not void my warranty on the engine. Thanks

I run 10/30 mobil 1 synthetic but you can run 10/30 or 10/40 in these mowers depending on what the temperature is in your area. The hydro's call for 10/40 and the engine calls for 10/30 in the manual I think.

So it's ok to run synthetic oils in them? Are synthetic oils really that much better? I put 10w-30 Valvoline in it. Is that ok?

I think that synthetic has it's benefits, it doesn't break down as fast as regular oil. You are fine using valvoline 10w30 in your mower.
