Sinclair Synthetic Blend Heavy Duty Diesel Engine Oil Heavy Duty Engine Oil
OEMs have advanced engines design to improve fuel economy, reduce emissions and extend oil drain intervals. And Sinclair has innovated and improved engine oil technology to stay in front of these changes.
Sinclair Synthetic Blend Heavy Duty 15W-40 CK-4 Diesel Engine Oil gives you unsurpassed protection and better performance, especially in very cold or hot temperatures.
- Improved fuel economy.
- Outstanding extended drain capability.
- An advanced lubricant that meets or exceeds OEM requirements.
Performance You'll Notice
Sinclair Synthetic Blend 15W-40 CK-4 delivers, with outstanding protection and performance. It controls friction and reduces metal-to-metal contact in today’s engine designs as well as older engine models.
Three Keys to Better Performance.
Sinclair Synthetic Blend 15W-40 CK-4 gives you:
Performance
- Extended drain intervals that help achieve fuel economies when following OEM recommendations and oil analysis.
Strength
- Increases wear protection up to 53%.1
- Unbeatable protection against bearing and engine wear caused by cavitation through increased oil aeration.
Durability
- Deposit control up to 63%2 and better oxidation control up to 83%.2
- Higher starting TBN (10) gives increased oxidation control and protects against the acid buildup that causes rust and corrosion.
1 To measure friction reduction benefits, engineers used the ball-on-disk traction test.
2 Compared to new limits of API CK-4 requirements.
Applications
Product and grade is diesel engine oil recommended for naturally aspirated and turbocharged four-stroke diesel engines in which the API CK-4 service categories are recommended. It is formulated for engines operating under severe service and a wide range of cold and hot temperatures.
- It is backward compatible for CJ-4 and older API service categories.
- Approved by or meets requirements of major OEMs such as Cummins, Detroit Diesel, Mack/Volvo, Paccar, Navistar, Caterpillar, and others.
