Sinclair Conventional 10W-40 Motor Oil

Conventional Motor Oil Passenger Car Motor Oil

Sinclair Conventional 10W-40 Motor Oil is specifically formulated for the needs of older vehicles and/or higher-temperature climates, where thicker oils may be preferred. It offers the following:

  • Thermal breakdown resistance and deposit formation reduction, for better, longer-lasting engine protection than conventional oils provide.
  • Engine cleaning additives.
  • A strong film barrier that controls friction, resists wear and prevents contact between metal surfaces.

Conventional Motor Oil: Performance You'll Notice

Specifically formulated to give you:

Protection

Unsurpassed control of friction and wear.

  • Designed to work, even under the most severe, extreme environmental conditions and engine stresses.

Toughness

A strong oil film helps avoid metal-to-metal contact, even under stress.

  • Excellentprotection 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.1

Endurance

Extends oil life by withstanding heat and shearing.

  • Excellent control of oxidation and deposits.
  • Keeps working and protecting, even in harsh conditions.

¹ To measure friction reduction benefits, engineers used the ball-on-disk traction test.

Applications

  • Provides performance benefits for passenger cars, light trucks and sport utility vehicles, including new and rebuilt engines.
  • Exceeds ILSAC GF-5 performance requirements.
