Deciding what proper viscosity oil you should use in your diesel engine has been a topic of debate for many years. While all truck manufacturers offer an informed suggestion via your owner’s manual, the question of which to use is one that pops up on the internet seemingly every day. Do you need a 10W-30 diesel oil or is 10W-40 a better option?

Always go by what the engine/truck manufacturer recommends, and many truck manufacturers are now recommending a 10W-30 weight oil for use in certain diesel engines. Deviating from that could cause issues with lifters and other facets of the engine. To keep that truck engine running smoothly, AMSOIL has added a new 10W-30 diesel oil to its Commercial-Grade family of products.

This new AMSOIL 10W-30 Commercial-Grade Diesel Oil is designed for truck owners looking to utilize an upgrade over conventional and other synthetic-blend oils in heavy-duty equipment and vehicles. It is a synthetic-blend product with greater than 50-percent synthetic content to help keep trucks and equipment operating at peak performance.

According to AMSOIL, who relied on third-party testing in the Detroit Diesel DD13 Scuffing Test for specification DFS 93K222, this new 10W-30 diesel oil provides twice the wear protection of the industry standard to help reduce maintenance costs and promote equipment longevity. It features a low rate of volatility that helps reduce oil consumption and contributes to fewer combustion-chamber deposits. AMSOIL 10W-30 Commercial Oil flows dependably in cold temperatures while maintaining power and fuel efficiency for reliable startup and engine protection.

“There is a growing demand for 10W-30 diesel oils in the commercial realm,” said AMSOIL Heavy-Duty Market Manager, Brett Granmo. “Our Commercial-Grade line provides a great solution for commercial operations looking for upgraded protection for their equipment without increasing costs.”

AMSOIL 10W-30 Commercial-Grade Diesel Oil is blended to meet the latest API CK-4 diesel oil specification and is compatible with other conventional and synthetic oils. Since it is formulated with more than 50-percent synthetic content it has the ability to minimize viscosity change, keep soot particles suspended independently, and help prevent the formation of larger, wear-causing particles.

The next time you are doing the lubrication maintenance your truck needs, it might be time to take a look at what AMSOIL has to offer.
