Sinclair Synthetic Blend 10W-40 Motor Oil
Synthetic Blend Motor Oil Passenger Car Motor Oil
Sinclair Synthetic Blend 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:
Performance
Unsurpassed control of friction and wear.
- Designed to work, even under the most severe, extreme environmental conditions and engine stresses.
Strength
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
Durability
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-6 performance requirements.
