  • Light Duty Trucks
Alpha Syn 5w/20 is a premium quality SL/SJ engine oil designed for all-weather operation of passenger cars and light duty trucks. Alpha Syn 5w/20 is a blend of the highest quality base oils and selected additives. It is compounded with Frontier’s exclusive ETX extender additive package and has a much higher viscosity index (VI) than conventional oils. This exclusive formulation provides excellent protection against deposits resulting from long term high temperature operation. It also provides excellent protection against sludge deposits resulting from the severe service of short trips and stop and go driving.

Alpha Syn 5W-20 anti-wear additives minimize wear and scuffing of metal surfaces under boundary lubrication conditions. The detergent-dispersant additives protect against sludge formation and varnish deposits. The anti-oxidant additive provides excellent resistance to oxidation during the higher operating temperatures common in the modern high revving, high performance, low emission engines being manufactured today. Rust and corrosion additives protect engine parts during engine operation and shut down.

Alpha Syn 5W-20 contains a unique acid neutralizing additive package that protects against the formation of acidic compounds. These selected alkaline additives give a much longer lasting TBN than regular engine oils. This higher, long lasting TBN provides protection against acid buildup and allows longer oil change intervals than conventional engine oils.


Alpha Syn 5W-20 Engine Oil provides the following advantages:

  • Meets or exceeds the performance requirements of current and proposed engine oil specifications
  • Protects low-emission engines from wear and deposits
  • Resists soot-related viscosity increase
  • Extends engine life while meeting emissions requirements
  • Improves engine durability, keeping equipment in as new condition
  • Allows extended oil drain intervals
  • Resists thermal breakdown
  • Has excellent low temperature performance
  • Is more environmentally friendly PERFORMANCE CAPABILITIES:
