Synthetic Blend Passenger Car Engine Oil Formulated with 70% or Greater Re-Refined Base Stocks

Phillips 66®Shield Firebird Motor Oil is an environmentally responsible, part-synthetic automotive engine oil designed to provide excellent engine protection for both turbocharged gasoline direct-injection, conventional gasoline-fueled and flex-fueled passenger cars and light trucks under all operating conditions. It is formulated with a blend of synthetic and 70% or greater high-quality re-refined base stocks. The use of re-refined base stocks helps lessen the environmental impact of disposal of used oil.

Features & Benefits

  • Helps protect against low speed pre-ignition (LSPI) in turbocharged gasoline direct-injection engines (TGDI)
  • Meets ILSAC GF-5 requirements for new cars under warranty
  • Friction-modified for improved fuel economy
  • Resists viscosity and thermal breakdown at high temperatures
  • Protects against sludge and varnish formation
  • Protects against wear
  • Protects against rust and bearing corrosion
  • Good low-temperature pumpability for easier cold starts
  • Good foam resistance
  • Formulated to protect turbochargers and emissions control system catalysts
  • Formulated for use in vehicles operating on ethanol-containing fuels up to E85
  • Lessens the environmental impact of disposal of used oil


  • Turbocharged gasoline direct-injection, conventional gasoline-fueled and flex-fuel passenger cars, light trucks and sport utility vehicles, including gasoline-electric hybrids, especially when operating under severe conditions
