I wouldn't put too much stock in what a salesman says as many (most) of them barely know the color of the equipment they are selling.
The salesman and dealer staff jobs are to make sure you keep coming back so they can sell you more stuff for your tractor. They often will bad-mouth any other products and insist you have to use JD only lubes. All you are is 'money in the bank' to the dealer.
Makes you wonder how good their oil is if they insist you change it after only 10 hrs of use. Do you take you car or truck back to the auto dealer after 100 miles for an oil change? All least the have some ethics, the powersports dealers want your money and they will say and do anything to get some more of it anyway they can.
I been running 100% synthetic in my 2010 X728SE since about 5 hrs. The dealer strongly recommended I wait till 50 hrs before installing synthetic oil but I told him that was bs. My car came with synthetic oil and every Corvette since the 1990's has comes with, and requires synthetic oil.
