Royal Purple HP Straight Grade Motor Oil is specifically formulated for vintage automotive, off-highway agricultural and recreational, 
and older non-turbo diesel engines. Many older gasoline and diesel engine recommend the use of a straight (mono-viscosity) grade 
engine oil, and these engines also benefit from elevated wear-protecting chemistry, beyond what is allowed in current engine oil 
specifications intended for late-model, emissions-controlled vehicles. Royal Purple HP Straight Grade engine oils provide enhanced 
protection against wear and friction with a zinc/phosphorus enhanced formulation, and Royal Purple’s proprietary additive technology, 
Synerlec®. 

Synerlec® is Royal Purple’s proprietary additive chemistry that greatly increases the protective film strength of the oil, reducing metal to 
metal contact, friction and wear. Synerlec® also increases the oil’s resistance to thermal degradation, reducing deposit formation and 
lengthening the oil’s useful life.

Performance Advantages:
  • UNSURPASSED WEAR PROTECTION – Elevated anti-wear additive and Synerlec® additive technology prevents wear of piston rings, valve train, and other components beyond licensed HD diesel engine oils
  • OUTSTANDING OXIDATION RESISTANCE – Less thermal breakdown allows longer oil drain intervals
  • INCREASED EFFICIENCY – Synthetic base oils and Synerlec® additive technology reduce parasitic loss, increasing fuel economy
  • OUTSTANDING DEPOSIT CONTROL – Keeps engines cleaner, ensuring maximum performance
  • SUPERIOR CORROSION PROTECTION - No rust observed in standard industry testing
