Looking at Future Diesel Lubricant Technology
Copyright 2008 Shell Global Solutions (US) Inc.
Viscosity grades of oil can effect fuel economy
Europe
European FE grades available 5W-30 and 10W-40 and approved by OEMs.
US
•
Fuel economy interest growing with high fuel prices
•
Proposed legislation under review to look at FE improvement for heavy and medium duty vehicles from 2011
•
US market currently predominantly 15W-40 (>90% total) with 10W-30 in colder climate (Canada) plus limited 5W-40 synthetic market segment
•
Traditional concern regarding durability of xW-30 grades
•
Interest growing in FE grades from OEMs as European-type engines introduced into US market (MB/DDC, Volvo/Mack, MAN/International Trucks).

Innovative Technology: Delivering Energy-Saving Performance
Challenge: Using low-viscosity energy-saving oils without compromising protection
–
Reducing friction and oil film thickness
–
Maintaining protection against wear
–
No reduction in protection and durability
Solution: Energy-saving oils with exceptional durability Use of synthetic technology base oils with anti-wear
boosters to deliver the optimum balance between efficiency and protection
–
Novel anti-wear boosters help maintain protective oil films
–
Synthetic technology base oils more resistant to thinning at high temperatures
