FS Engine Guard Synthetic Blend SAE 5W-20, 5W-30 & 10W-30

FS Engine Guard Synthetic Blend Motor Oil is formulated with synthetic and highly refined conventional base oil, a shear stable viscosity index improver and utilizes an advanced detergent and dispersant package to provide excellent engine cleanliness and protection against low speed pre-ignition (LSPI). In addition, FS Engine Guard contains anti-wear and friction modifiers, foam suppressants, corrosion inhibitors, and a robust antioxidant package to help prevent timing chain wear and turbocharger deposits in next generation gasoline engines. It is also backwards compatible to protect older engine technologies.


Features and Benefits: 

  • Displays the API “starburst” symbol, indicating it is certified for use in gasoline engines
  • Meets, and in some cases, exceeds API SP Resource Conserving and ILSAC GF-6 specification requirements
  • Formulated with a partial blend of synthetic base oil to meet NOACK Volatility and ASTM D5800 test requirements
  • Provides protection against low speed pre-ignition (LSPI), which is a phenomenon that can lead to pre-ignition knock that can occur in turbocharged, gasoline direct-injected engines
  • Offers improved protection against timing chain wear and turbocharger deposit build-up in newer gasoline engines
  • Features better oxidation stability, improved piston cleanliness and better wear control
  • Passes all current industry-standard gasoline engine tests
  • Features a high-quality detergent package for excellent engine cleanliness
  • Provides excellent anti-wear protection of critical engine parts
  • Features a high viscosity index that ensures easy cold starting and protective films that reduce viscosity breakdown
  • Formulated with a high level of dispersancy that protects against sludge, engine rust, and corrosion under severe operating conditions
  • Offers low volatility for reduced oil consumption and protection of the emission-control system catalyst
  • Designed for today’s gasoline engines that operate at higher temperatures
  • Not formulated for use in heavy-duty turbocharged diesel engines; use FS Suprex Gold ESP for those applications
