Havoline ProDS Full Synthetic Motor Oil SAE 5W-30
a. Delo CXJ was recommended for Japanese OEM diesels; b. Delo SHP for European; and c. Delo LSA for US designed engines.
The paper describes power density, piston ring location, sump capacity, crown thickness, and the requirement for more/less dispersants, greater/lower sulfated ash amongst others to deal with the nuances of design. Has the convergence to modern HDMOs been driven by either
a. Convergence in design parameters by the various OEMs; or b. Improvements in the lubricant technology such that the apparent shortcomings in the Caltex paper have been reduced to the point that they no longer are of significance?
The need for diesel engine oil to be compatible and support the durability of exhaust gas treatment devices in diesel powered vehicles equipped with same and the engine oil performance requirements with increasingly longer recommended service intervals have been major influences in diesel engine oil technology in the last 20 years.
The influence of engine oil on LSPI is being evaluated through tests and Chevron is developing engine oils to pass LSPI testing.
Delo 400 LE SAE 15W-40 HTHS @ 150 °C by ASTM D4683 is > 3.7 mPa.s.
Delo 400 XLE SAE 10W-30 HTHS @ 150 °C by ASTM D4683 is > 2.9 mPa.s.
Yes, our OAT components include 2-EHA and have been used successfully by most NA OEM’s and fleets over the last 25 years. Every HD truck and engine manufacturer in NA currently approves and/or uses a 2-EHA containing coolant as factory fill.
