Sinclair Full Synthetic 5W-30 Motor Oil

Sinclair Full Synthetic Motor Oil Passenger Car Motor Oil

Sinclair Full Synthetic 5W-30 Motor Oil is a pure and technologically advanced formulation that provides unsurpassed protection and performance and provides the following benefits:

  • Sinclair dexos1™ Approved Motor Oils meet or exceed GM dexos1™ specifications for warranty requirements for all GM automotive gasoline engines currently in use worldwide, and are fully licensed by GM.
  • Increased fuel mileage, maximum horsepower and better acceleration.
  • A strong, consistent molecular structure that forms a film layer that controls friction, resists wear and prevents contact between metal surfaces.
  • Outstanding performance in extreme hot or cold conditions, stop-and-go traffic, recurring short trips, heavy loads and dusty conditions.
  • Performance that meets or exceeds API, SP and ILSAC GF-6 requirements

Developed for the Engine Designs of Today

OEMs have changed their engine designs to be lighter, yet still demand increased horsepower. And that means higher demands on motor oils. Sinclair Full Synthetic delivers, with technology and formulations that have kept pace with those ever-changing engine demands.

Sinclair Full Synthetic Motor Oil: Performance You'll Notice

In addition to the peace of mind that comes with Sinclair’s 100+ years of lubricant technology, Sinclair Full Synthetic 5W-30 Motor Oil delivers the following:


Controls friction and wear over 80% better than current API requirements.1

  • Increased fuel economy and reduced fuel costs without losing engine protection and performance. You’ll also notice increased acceleration.
  • Longer periods between oil changes.
  • Formulated to handle the most severe conditions.
  • 100% pure synthetic, with molecules that provide superior, long-lasting engine protection and performance.


A strong oil film serves to resist metal-to-metal contact, even under stress.

  • Outstanding wear protection.
  • Augmented friction reduction - Sinclair oils are heat-reactive, and produce a vital barrier that reduces friction and protects metal surfaces.2


Weathers heat and shearing to extend oil life.

  • Engineered to handle the most severe or extreme conditions.

1 Based on Sequence IV Wear test.

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


  • All gasoline- and flex-fuel cars, light trucks and SUVs, including gasoline-electric hybrids, notably under severe conditions.
  • Designed to protect turbochargers and emission control system catalysts.
  • Ideal for vehicles operating on fuels up to E85 ethanol.
