The lubricant offers a high-performance optimized additive package that allows for extended drain intervals, Shell noted.
It has a drain period of 100,000 miles in regular service, Shell said. Field trials of equipment fitted with Allison heavy-duty automatic transmissions have shown a drain period of 50,000 miles in severe service, the company added.
If operators wish to extend the drain period beyond 50,000 miles in severe service, used oil analysis is required to determine the condition of the oil.
