    I wasn't given a manual for my Scag 52’ WB PRO V so I had to print one online. Yet, the manual doesn't tell me what type of motor oil goes in the mower. It refers me to Kawasaki's website which is extremely confusing.

    I know my mower is a 23hp Kawasaki, but does anyone know the weight of motor oil to use? Thanks

    10w30/SAE30W. I use the sae30w in warm weather and 10w30 in the cooler weather.

    It should say it on the dip stick, I know it though It's 10w-30 or straight 30w

    Head to the most expensive place in town and buy the most expensive synthetic oil that you can and then make sure you change it every 50 hours. That's the advice of 90% of the members of Lawnsite. And don't forget to change that $10 oil filter every 50 hours too.

    Or you can do like the manual says...

    Quality SAE 30 or 10w30 conventional oil is more than sufficient. Change the oil every 100 hours and the filter every 200 hours.

    Well, actually, the manual for the Kawasaki engines on my Gravely's shows SAE 30 and 10w-30 and 10w-40 as good for ambient temps up to around 95 F. Above that, and to temps as low as 68F, straight 40 is recommended. However, I'm not sure where one would purchase straight 40 viscosity oil. Perhaps it is available in some specialty shops, but I've never seen it at any automotive or chain stores.

    As for myself, I run synthetic 10w-40, and did so last year when the temps were as high as 111 with no problems. The manual states, and I've found from my experience, that you will have some oil consumption using multiple viscosity oils. I generally have to add a little about every 25 hours of operation, but it would probably not actually get down to the add mark or below in less than 50 hours.
