Diesel maintenance learning library
Use these lessons to understand a choice before comparing products.
Before the trailer goes on
Find the towing or special-service instructions for the truck’s model year and engine. Compare the required oil specification as well as any permitted viscosity choices. Trailer weight alone does not identify the right oil, and a heavy-duty product name does not verify a match. Record the installed product code so a future top-up uses the same documented choice.
After a change in use, review the service plan and the separate drivetrain-fluid requirements. Do not infer that an engine-oil upgrade extends axle or transmission service. If the truck makes many short trips between towing assignments, read its regeneration instructions and treat dashboard warnings independently of the oil-change reminder.
FIRST, MATCH THE ENGINE
Your truck is the starting point.
Choose your engine family for a quick starting guide. Confirm fitment in the official lookup before buying.
Ford Power Stroke owners
Use your Ford truck’s exact model year and engine. Different Power Stroke generations can have different oil and service requirements.
Ram Cummins owners
Identify the Ram model year and Cummins engine. Include your towing and operating conditions when reviewing the permitted oil grades and service schedule.
Chevrolet & GMC Duramax owners
Identify the Chevrolet or GMC model year and engine displacement. A smaller Duramax pickup should not automatically use a heavy-duty Duramax recommendation.
Smaller diesel pickup owners
Use the specific engine and model year. Light-duty diesel applications can have different oil requirements from three-quarter-ton and one-ton pickups.
Identify your pickup
Have the model year, make, model, and engine ready. Include engine displacement when you know it.
Check the requirements
Confirm oil viscosity, performance specifications, capacity, and filter fitment in the lookup and owner’s manual.
Choose how you buy
Compare the suitable oils, select the right package size, and review personal or business account options.
COMPARE YOUR OPTIONS
Start with the right
diesel engine oil.
Compare two core oil families below, then browse the complete pickup-care selection.
Max-Duty
100% Synthetic Diesel Oil
A premium AMSOIL diesel oil family to consider when listed for your application.
- Explore for demanding operating conditions.
- Review the exact product’s application and service-life guidance.
- Compare the permitted viscosities for your engine.
100% Synthetic
Diesel Oil
An AMSOIL synthetic diesel oil family for owners comparing protection and purchase cost.
- Consider for a regular maintenance routine.
- Compare against your manufacturer’s requirements.
- Check the exact oil and filter service instructions.
A familiar grade such as 15W-40 is not automatically correct for every diesel pickup. Check the exact application before choosing 5W-40, 10W-30, 15W-40, or another grade.
Identify vehicle & check specifications →Maintenance products to explore for Diesel Pickup Owners
These cards cover lubrication and maintenance product types for the engines, components and supporting equipment discussed on this page. Compare alternatives against your exact application; a vehicle-type label alone does not establish fitment.
Start with the job. Confirm the exact application.
Possible application: these are product types to investigate for this vehicle or equipment group. The cards do not confirm compatibility with your individual machine.
Verified fitment: requires a match to your exact year, make, model, engine and installed component in a current application guide or manufacturer documentation. No card on this page is labeled as verified fitment.
Before ordering, identify the component, compare its required lubricant specification and viscosity or exact filter part number, and check capacity and service instructions. For modified equipment, identify the components actually installed.
105 products and 19 filter families to explore. Cards link to product details and available package choices.

Compare the product category before choosing a card
Use these guides to compare product families and requirements. Your exact engine or component still controls selection.
No matching products in this guide. Try a broader name or product code.
The correct transfer-case fluid depends on the unit. Some applications call for an ATF listed above; others require a different fluid. Look up the transfer case separately and confirm a listed AMSOIL recommendation.

Oil, fuel, air & other filters
Choose filters by exact vehicle application or a verified cross-reference. Start with the AMSOIL lookup for oil filters and other fitted parts; the full filter catalog also includes products sold by AMSOIL from other manufacturers.
PowerCore filter families include Ford 6.0L Power Stroke and GM 6.6L Duramax applications. Verify the year and air-box configuration before selecting a part.
Identify vehicle & check specifications →Browse all filters sold by AMSOILAlready have a bypass system?
Match replacement filters, fittings, seals, sampling valves, adapters, and brackets to the exact system and installation instructions. The AMSOIL catalog includes bypass replacement parts; ask Kyle with your system number and part code before ordering.

VIEW DETAILSYOUR ROUTINE MATTERS
What does your pickup do?
Use your operating conditions to guide the maintenance conversation.
Towing & hauling
Tell us about the trailer, load, terrain, and towing frequency. Check whether your manual calls for a severe-service schedule.
Daily driving & short trips
Include repeated short journeys and idle time when reviewing service needs. Mileage alone does not describe every operating pattern.
Cold-weather operation
Use the manufacturer’s temperature guidance to select a permitted oil grade. Plan fuel treatment separately from engine lubrication.
Older or modified trucks
Share engine changes, tuning, and competition use. A stock vehicle lookup may not fully describe a modified application.
ENGINE OIL IS ONE PART OF THE PLAN
Give diesel fuel
its own attention.
AMSOIL Diesel 4-IN-1 Fuel Additive combines injector-cleaning, cetane-boosting, cold-flow, and lubricity benefits. Review its label and treatment directions for your use.
Explore Diesel 4-IN-1Before adding a treatment
- Match the product to the purpose and season.
- Calculate the dose from the label and fuel volume.
- Add it to the diesel fuel tank—not the DEF tank.
- Check current product availability before ordering.
Fuel additives do not replace engine oil, filters, or scheduled maintenance.

Before you order.
What is the best AMSOIL oil for my diesel pickup?
Start with the exact year, make, model, and engine in the AMSOIL Auto & Light Truck Lookup. Then compare the recommended products with the specifications and operating conditions in your owner’s manual. There is no single oil grade that fits every diesel pickup.
Should I use 5W-40, 10W-30, or 15W-40?
Use a viscosity permitted for your specific engine and conditions. Ambient temperature, towing, engine design, and manufacturer requirements matter. The numbers on the bottle alone do not establish compatibility.
Do Power Stroke, Cummins, and Duramax engines use the same oil?
Some applications may share a recommended product, but brand names alone are not enough to confirm that. Verify the model year, engine, viscosity, and required specifications before ordering.
Can smaller diesel pickups use the same oil as heavy-duty pickups?
Do not assume they can. Smaller diesel engines can have different specifications. Use the lookup for the exact engine rather than selecting oil from a larger truck’s recommendation.
How often should I change my diesel pickup’s oil?
Follow the applicable manufacturer maintenance schedule and the service-life instructions for the exact oil and filter. Review severe-service requirements when towing, idling, or making repeated short trips. Extended intervals require applicable product guidance and, where appropriate, oil analysis.
Can I use diesel fuel additives instead of DEF?
No. Diesel fuel additives go into diesel fuel according to their label. Diesel exhaust fluid belongs in the separate DEF system on vehicles equipped with one. Neither replaces the other.
How can I save when buying AMSOIL for my personal pickup?
An AMSOIL Preferred Customer membership offers savings of up to 25% on standard retail online pricing, subject to program terms. Review the current membership options and compare the membership fee with your expected purchases.
What if my pickup is modified or used for competition?
Factory application guidance may not fully cover a modified engine. Tell Kyle about the engine, modifications, fuel, and use so he can help you identify the information needed for an appropriate recommendation.
