Motor Oil Weights for Heavy-Duty Diesel Equipment
We have been supplying heavy-duty diesel motor oil since we first started crafting our synthetic motor oil for the masses. For diesel equipment, we offer a few different motor oil types, including our Signature Series, which offers six times the wear protection and maximizes fuel efficiency, Heavy-Duty, which offers four times the wear protection and excels in extreme temperatures, and Commercial Grade synthetic motor oil, which offers two times the wear protection and is a significant upgrade on conventional oil. All of these synthetic motor oil types come in a variety of viscosities, including 0W-40, 5W-30, 5W-40, 10W-30, and the most popular heavy-duty motor oil type, 15W-40.
Picking between these three lines usually comes down to how many hours your equipment runs and how far you want to push your drain interval. Signature Series makes the most sense for equipment that runs hard, year-round, where extended drain intervals translate directly into less downtime for oil changes. Heavy-Duty is a strong middle ground, still built for demanding conditions and extreme temperatures, but at a price point that works well for equipment with moderate annual hours. Commercial Grade is the right call when you want a genuine step up from conventional oil without paying for maximum extended-interval performance, common for lower-hour equipment or backup machines that don't see year-round use.
Lubricants & Protectants for Heavy-Duty Diesel Equipment
With one of the largest selections of lubricants and protectants for diesel equipment in Ohio, our lubes and fluids will keep your excavator, mobile crane, or grader ready to roll. From heavy-duty bypass systems to diesel additives, and even transmission fluid and hydraulic oil, our world-class synthetic lubricants and protectants will not only extend the life of your rig but also ensure your heavy equipment keeps running when you need it most.
Bypass filtration deserves a closer look for equipment like yours specifically. A standard oil filter typically catches particles down to about 20 microns, but a bypass system captures particles down to 1 to 2 microns, catching the fine soot and metal shavings that a standard filter simply can't. For equipment that runs long hours under heavy load, that extra layer of filtration can meaningfully extend both oil life and component life, which matters even more when factoring in the labor cost of servicing equipment in the field rather than a shop. Many fleets also run regular oil analysis alongside extended-interval synthetic oil, since sampling lets you verify your oil is still performing before extending an interval further, rather than guessing.
Filters for Heavy-Duty Diesel Equipment
As one of the best heavy-duty filter options in Ohio, we are a proud partner of Donaldson, which offers a better-than-OEM blue heavy-duty air filter that not only reduces engine wear on your machine but also extends the service intervals of your Bobcat, backhoe, or front-end loader. Construction and job-site environments push a huge volume of dust and debris through an air intake compared to typical road use, which makes air filtration especially important for heavy equipment specifically. A clogged or underperforming air filter doesn't just reduce airflow, it can also let abrasive particulate straight into the engine, accelerating wear on components that are expensive and time-consuming to replace in the field.

Frequently Asked Questions
No Dumb Questions, Just Dry Dipsticks
What extra protection do AMSOil heavy-duty diesel products offer?
Our synthetic motor oil is more than just oil; it is a protectant, a detergent and a cleaner. Our Signature Series, our most popular heavy-duty diesel oil, delivers six times the wear protection of traditional oil, maintains viscosity under extreme pressure, maximizes fuel efficiency, and maintains its advanced formula even in extreme temperatures compared to other oils on the market.
What is the difference between Max Duty and normal synthetic motor oil?
Max Duty Signature Series Synthetic Motor Oil is designed for heavy equipment. It provides 6 times the wear protection to keep your motor running while minimizing oil consumption and maximizing fuel efficiency throughout the machine. With our Max Duty motor oil, you can enjoy extended drain intervals, which means more hours digging, lifting or grading.
Does this motor oil work for all equipment types and brands?
Yes, our synthetic motor oil will work with all equipment types and brands, and we offer our Signature Series, Heavy Duty Series and Commercial Grade synthetic motor oils in a variety of viscosities to cover almost every piece of heavy equipment out there. Whether you have a cat, a John Deere, a JCB, or even a Volvo, one of our motor oils will be the ideal motor oil for your engine.
What is bypass filtration, and is it worth adding to heavy equipment?
Bypass filtration adds a secondary, finer filter alongside your standard oil filter, capturing particles down to 1 to 2 microns compared to the 20 microns a standard filter catches. For equipment that runs long hours under heavy load, this extra layer of filtration can meaningfully extend both oil life and component life, which is especially valuable when factoring in how much more it costs to service equipment out in the field versus in a shop.
Should I run oil analysis alongside extended-drain synthetic oil?
It's a smart practice, especially for fleets running extended intervals. Oil analysis lets you verify your oil's condition and additive levels before pushing an interval further, rather than guessing based on hours alone. If you're running Signature Series with extended intervals, periodic sampling gives you confidence you're not extending too far for your specific equipment and duty cycle.
