New 10W-30 Joins Signature Series Max-Duty Lineup

AMSOIL Signature Series 10W-30 Max-Duty Synthetic Diesel Oil provides a premium, fuel-efficient choice.

Fuel expenses comprise a significant portion of any fleet’s budget, and optimizing fuel economy is essential for reducing costs and maximizing the bottom line. To help customers reach this goal, many original equipment manufacturers (OEM’s) now recommend 10W-30 diesel oil for improved fuel economy and cost savings.

New Signature Series 10W-30 Max-Duty Synthetic Diesel Oil (DTT) is ideal for customers looking for premium protection and improved fuel efficiency afforded by a 10W-30. It provides outstanding protection for over the road trucks, smaller off-road equipment and turbo-diesel pickups specifying 10W-30 (Ford specifies 10W-30 for normal service).
