LUBRICANT COST ANALYSIS AND INFORMATION
Royal Purple uses 2.28 % less power than HD RotoFluid. Summit uses 1.37 % less power than HD RotoFluid. (Synoil analysis is incomplete at this time.)
Converting the percentage differences into dollar differences requires a known cost per kilowatt-hour. We assume that our cost is $0.0708 / kWhr.
Below is the calculated cost of running the different lubircants on a 13 kW base compressor.
Note: the compressor uses 13 kW with HD RotoFluid but it uses less power with other lubricants which will be translated into the cost.
Lubricant % difference hourly cost yearly cost HD RotoFluid ----- $0.9204/hr $8063 Summit 1.37% $0.9078/hr $7952 Royal Purple 2.28% $0.8994/hr $7879 Note: More data is needed for other lubricants to complete analysis.
