Royal Purple 15W-40 Synthetic Motor Oil, 1 gal:
  • 1 gal of Royal Purple motor oil provides better wear protection: Enhanced additive technology prevents metal-to-metal contact beyond both Dexos1 and ILSAC GF-5 specs
  • Increased fuel efficiency: A low coefficient of friction results in optimized fuel efficiency (the fuel economy of our 5W-30 meets the fuel economy requirements of a 5W-20 oil)
  • Diesel engine oil gives better protection of the expensive catalytic emissions system: Patented ZDDP additives optimize emissions catalyst system life
  • Improved compatibility with fuels containing ethanol: Patented additive technology prevents the white sludge and lubrication starvation that can occur with 20 percent or higher ethanol fuel
  • Royal Purple 15W-40 Synthetic Motor Oil has superior corrosion protection: No rust observed in standard industry testing
