    Would you reccomend stardard 20W-50 motor oil, or a Valvoline racing oil,, or a synthetic motor oil to run in my ZT 2800 hydro's on my ZT XT 48 Gravely?

    I was looking at the synthetic's like this one


    or just plain ol oil like this


    I worry that the additives in the synthetic's might not be cool or needed in the hydro's,, in therory it sounds nice to think better oil would be better.

    How bout Synthetic oil in the 24HP Kaw engine??

    So here I am asking the pro! :rolleyes:

    Use 20W-50 for the hydro's. Synthetic would be overkill, and not worth the extra $$$. Same for the engine. Standard oil changed regularly will keep the system clean.
