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.

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