Authors Abstract
Content
The cranking and starting characteristics of four multigrade and two single grade crankcase oils have been evaluated in three popular makes of diesel truck engines. Test results show average startability benefits of 13-15°F (7-8°C) when using a 15W40 multigrade relative to the 30 grade. These benefits increase to 18-20°F (10-11°C) for the 10W30 grade. Additional startability benefits are realized for the 5W20 “Arctic” type lubricants.
Minimum starting temperatures for each unit differ, yet startability benefits are similar when comparing the same oils.
