Synthetic Blend Motor Oil

OEMs engine designs continue to progress, and that means increased demands from motor oil. Sinclair Lubricants technology has progressed as well, and provides the friction and wear protection required by lighter, more powerful engines.

Our advanced motor oil chemistry improves viscosity retention and works to prevent friction and wear, in spite of severe engine temperatures.

Since 1922, Sinclair has been guided by its “Law of Lubricants” that states ‘for every machine and every degree of wear we protect, there is a scientific Sinclair oil to suit its speed and seal its power.’ That means performance people have been noticing for almost a century.

Sinclair Synthetic Blend Motor Oils: Performance You'll Notice

Synthetic Blend provides extra protection and peace of mind, compared with conventional oil, giving you:

Performance

Outstanding control of friction and wear more than 65% better than the latest API standards.1

Strength

Provides a strong oil film to protect rotating engine parts, even under extreme stress conditions.2

Durability

Stands up to the heat and shearing so it extends oil life.

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

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