This is quite important to understand the basic of using each word in any technical name of any product, let us understand the purpose of above written word.

H - Hydraulic oil 

L- Additives for increasing corrosion protection 

P- Additives for increasing load carrying ability 

68- Viscosity in centistokes @ 40 degree centigrade temperature
