*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)
*Better protection of the expensive catalytic emission 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% or higher ethanol fuel
*Superior corrosion protection*
No rust observed in standard industry testing
