Royal Purple

Royal Purple lubricants consistently deliver a higher level of performance across a broader group of equipment than other industrial oils, including the synthetic oils offered by our largest competitors. No other lubricant offers a lower Total Cost of Ownership for the majority of your plant equipment. The cost reductions consistently exceed the total cost of the product, often within a few weeks.

Royal Purple High Performance
Royal Purple High Performance

Royal Purple Motor Oil delivers superior protection, increases horsepower and torque, saves fuels and reduces heat, wear and emissions. It has unsurpassed oxidation stability that allows for extended oil drains and fewer oil changes, which saves you time and money and reduces the impact on the environment.

Royal Purple’s performance advantages come from a blend of synthetic oils plus Royal Purple’s proprietary Synerlec technology. Royal Purple Motor Oil is compatible with other mineral and synthetic motor oils. It’s available in 5W20, 5W30, 10W30, 10W40, 15W40, and 20W50 weights.
