    Where can I buy this?
    I have looked everywhere with no luck...

    Another question.... How many of you use it and what is it's purpose?

    It's a very expensive zinc based oil additive that's used in Hustler equipments Hydro systems. You can buy it at any Hustler dealer.

    If I recall correctly, if you use synthetic oil in your hydro system, PJ said you don't need Lubrizol. I actually do use it in conventional oil in my systems but it is expensive.

    But do a search on that in the "Hustler" forum before taking my advice.:hammerhead:

    I noticed a better "feel" by switching my SuperZ over to 15-50 Mobil-1 and did not use Lubrizoil.

    Cooling system or not, hydro systems get VERY hot when your working them hard (just reach your hand back to feel the exhaust of the hydro cooling fan sometime!)....With Mobil-1 being able to withstand higher temps than dino oil, it really should be in there in the first place. Plus, 15-50 is a thicker viscosity than 10-40.

    One thing i do notice is that the hydros get "sluggy" after they are warmed up.
    Do you think switching to the heavier grade oil will help that?
