Diesel Emission Standards

See how AMSOIL products perform in the lab and in the field.

Low emissions and superior lubricity in one oil

Diesel emission standards require the best in diesel engine oil

Diesel emission standards changed in 2007, all with the goal of reducing tailpipe emissions by 95%, and sulfur content in diesel fuel was reduced by at least 97%. When these regulations changed, the effect on diesel-powered vehicles was immediate, forcing manufacturers to include equipment like diesel particulate filters and DEF fluids to meet or exceed the new standards.

Protecting post-2007 diesel vehicles requires top-level engine oils that adhere to the FA4 standards or higher. Older oils can contaminate combustion chambers, fuel injectors, EGR systems, and DPF systems and leave expensive repairs in their wake. But oils like AMSOIL diesel engine oils that meet and exceed FA4 criteria? They not only protect your engine but minimize any effects on your powertrain or emissions system for consistent, long-lasting performance.

Diesel oils will help avoid wear on cylinder liners and piston rings

How AMSOIL diesel oils work for you

Whether you drive a long-distance highway tractor, a farm truck with a 6.7 Cummins, or a Duramax diesel-powered GMC, AMSOIL has a diesel motor oil that suits your application like none other. Combined with an AMSOIL oil filter, internal engine wear from soot and power-robbing deposits from viscosity controlling properties are a thing of the past.

Using one of the three AMSOIL diesel oils will help avoid wear on cylinder liners and piston rings, clean the crankcase of sludge, provide better cold-weather starts, and effectively reduce oil consumption and improve fuel efficiency.

Oil consumption comparison Choose from:

  • AMSOIL 100% Synthetic Diesel Oil in 0W-20 and 5W-30
  • AMSOIL Heavy-Duty Synthetic Diesel Oil in 10W-30, 5W-40, and 15W-40
  • AMSOIL Signature Series Max-Duty Synthetic Diesel Oil in five popular viscosities
