Sinclair Synthetic Blend 5W-30 Motor Oil

Synthetic Blend Motor Oil Passenger Car Motor Oil

As OEMs have changed and adapted engine designs to be lighter, while maintaining or even increasing horsepower, Sinclair Oils have changed and adapted as well.

Sinclair Synthetic Blend 5W-30 Motor Oil gives you the extra protection and peace of mind you just can’t get from conventional oil. It provides:

  • Thermal breakdown resistance and a reduction of deposit formations, so you get longer-lasting, tougher engine protection than conventional oils.
  • Additives that actually work to keep your engine clean and running smooth.
  • A strong friction-controlling film barrier that resists wear and prevents contact between metal surfaces.
  • Meets or exceeds warranty requirements for all automotive gasoline engines currently in use in U.S. and import cars and light trucks.

Synthetic Blend Motor Oil featuring Performance You'll Notice

Sinclair Synthetic Blend 5W-30 motor oil delivers the following benefits:


Friction and wear over 65% better than current API requirements.1

  • Protection that withstands even the harshest, most severe conditions.
  • More protection than conventional oil.


Provides a strong oil film to avoid metal-to-metal contact, even under stress.

  • Outstanding protection against wear, with molecules that actually bond and prevent metal-to-metal contact of rotating engine parts.
  • Heat-activated friction reduction that forms a vital barrier that protects against friction in metal surfaces.2


Extends engine life by withstanding heat and shearing.

  • Meets needs of new engine design strategies by providing better oxidation and deposit control under higher operating temperatures.
  • Excels in the harshest conditions.

1 As measured against the Sequence IV Average Cam Wear Limit for API SP.

2 To measure friction reduction benefits, engineers used the ball-on-disk traction test.


  • Provides extra performance benefits for passenger cars, light trucks and sport utility vehicles; including those with new and rebuilt engines.
  • Exceeds ILSAC GF-6 performance requirements.
