Sinclair Full Synthetic 5W-20 Motor Oil

Sinclair Full Synthetic Motor Oil Passenger Car Motor Oil

Sinclair Full Synthetic 5W-20 Motor Oil is a pure and extremely advanced formulation that delivers outstanding protection, performance and the following benefits:

  • Improved fuel mileage, maximum horsepower and increased acceleration.
  • Longer-lasting and better protection than conventional oils due to strong synthetic base oils and technology that provides a friction-controlling barrier that resists wear and prevents contact between metal surfaces.
  • Designed to handle extreme hot and cold driving conditions: stop-and-go traffic, recurring short trips, heavy loads and dusty conditions.
  • Meets or exceeds API SN and ILSAC GF-5 requirements.

Engineered with Today's Engine's in Mind

Sinclair Full Synthetic 5W-20 Motor Oil has kept pace with OEM’s as they continue to design advanced lighter engines with increased power loads.

Full Synthetic Motor Oil: Performance You'll Notice

Sinclair Full Synthetic 5W-20 Motor Oil delivers these benefits:


Controls friction and wear more than 80% better than the latest 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.

  • Unsurpassed 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.
