Note: The normal hydraulic oil change interval is at every 2000 Service Hours or one Year. By performing S O S oil analysis, the hydraulic oil change interval may be extended to 4000 Service Hours or two Years. S O S oil analysis must be performed at every 500 Service Hours or 3 Months in order to extend the hydraulic oil change interval. The results from the S O S oil analysis will determine if the hydraulic oil change interval may be extended. If S O S oil analysis is not available, the hydraulic oil change interval must remain at every 2000 Service Hours or one Year . Refer to the Operation and Maintenance Manual, "S O S Information".Note: Cat HYDO Advanced 10 has a 50% increase in the standard oil drain interval for machine hydraulic systems (3000 hours versus 2000 hours) over second and third choice oils - when following the maintenance interval schedule for oil filter changes and for oil sampling that is stated in the Operation and Maintenance Manual for your particular machine. 6000 hour oil drain intervals are possible when using S O S Services oil analysis. Contact your Cat dealer for details.
