AMSOIL Commercial & Fleet Accounts
Running trucks, tractors, or heavy equipment means fuel and downtime are two of your biggest costs. Independent SAE J1321 testing shows AMSOIL synthetic lubricants improving Class 8 diesel fuel economy by up to 8.2% — a number serious fleet operators ask to see the source on, not just take my word for. Below is exactly how a commercial account works, what it costs, and how the math holds up before you switch a single truck.
The Fuel-Economy Math
The 8.2% figure comes from an independent SAE J1321 Type II fuel-consumption test — the same industry-standard procedure trucking fleets use to validate any fuel-saving technology. It compared Class 8 truck-tractors running AMSOIL Series 3000 synthetic diesel oil against the same trucks running conventional lubricants, on the same route, with the same drivers and loads.
Here's how the 8.2% figure translates into real dollars for a mid-size fleet. These are illustrative assumptions — plug in your own truck count, mileage, and fuel spend, or call and I'll run your actual numbers.
| Fleet size | 25 Class 8 trucks |
| Average annual fuel spend per truck | $28,000 |
| Total annual fleet fuel spend | $700,000 |
| Fuel economy improvement (SAE J1321 tested) | 8.2% |
| Illustrative annual fuel savings | ~$57,400 |
Assumes fuel spend stays otherwise constant year over year. Actual results vary by route, load, driving conditions, and current maintenance baseline — this is a demonstration of the math, not a guarantee. Ask about a custom savings estimate for your specific fleet when you call.
That's before accounting for extended drain intervals, which is where the second half of the savings shows up — see the full AMSOIL Diesel Truck Oil Guide for engine-specific drain interval data by platform (Cummins, Duramax, Powerstroke).
What a Commercial Account Actually Gets You
No middlemen, no markup above AMSOIL's own pricing — the same structural advantage that applies to every account type through this dealership.
Wholesale Pricing
Commercial accounts buy at wholesale, with volume discounts that increase automatically as your annual purchase total grows — locked in for the year once you qualify.
Net-30 Credit Available
Apply for a 30-day credit line instead of paying by card upfront, or use standard payment methods — your choice.
No Minimum Orders
Order exactly what you need, on your schedule. No inventory commitment, no required autoship.
Free Shipping at $400+
Orders of $400 (US) or $450 (CAD) and up ship free. Under that, a flat shipping rate applies — group orders to clear the threshold.
Technical Support
Direct access to AMSOIL's technical services team plus my own 20 years of field experience with diesel, ag, and construction equipment — not a call center reading a script.
MyAMSOILGarage Tracking
Free tool for logging maintenance across your whole fleet — drain intervals, service history, and reminders in one place, whether or not every vehicle runs AMSOIL.
Who This Is For
Over 20 years I've built commercial accounts across the Houston metro and Gulf Coast in these industries specifically:
Beyond Fuel: What Extended Drain Intervals Actually Save
Fuel economy is one side of the ledger. The other is how much less often you're pulling a truck off the road for an oil change — and independent lab testing backs up why AMSOIL supports longer intervals in the first place.
34% Less Engine Wear
ASTM D4172 Four-Ball Wear testing: AMSOIL Signature Series 5W-30 produced a 0.40mm wear scar vs. 0.61mm for Mobil 1 Extended Performance.
~4x Fewer Turbo Deposits vs. Mobil 1
ASTM D6335 TEOST 33C deposit testing: 7.0mg of turbo deposits for AMSOIL vs. 28.2mg for Mobil 1 Extended Performance — critical for turbocharged diesel engines running continuous heavy loads.
TBN of 12.5
Higher Total Base Number means more acid-neutralizing reserve left at the same mileage — the reason drain intervals can stretch well past conventional 5,000–10,000 mile limits.
Fewer oil changes means fewer trucks sitting idle in the shop instead of running a route. That labor and downtime cost rarely makes it into the "price per quart" comparison — but it's usually the bigger number for a fleet manager.
Commercial Account vs. Other Ways to Buy AMSOIL
Not every business needs a full Commercial Account. Here's how the three account types actually differ for a business buyer:
| Account Type | Best For | Pricing | Resale Allowed? |
|---|---|---|---|
| Preferred Customer | Owner-operators, small businesses with just a few vehicles | Up to 25% off retail | No — personal/in-house use |
| Commercial Account | Fleets, farms, construction, shops using product in-house | Wholesale + volume discounts | No — in-house use only |
| Dealer | Anyone who wants to sell AMSOIL to others and earn commission | Wholesale, same as Commercial | Yes — resale is the point |
Not sure which fits your situation? See the full Preferred Customer breakdown or the Becoming an AMSOIL Dealer guide — or just call and I'll tell you straight which one actually saves you money.

Commercial Account Questions
How much can a fleet actually save switching to AMSOIL?
Independent SAE J1321 testing shows up to 8.2% improved fuel economy in Class 8 trucks, plus savings from extended drain intervals reducing labor and downtime. Actual results depend on your current baseline, routes, and equipment — call and I'll help estimate your specific numbers.
Is there a minimum order size for a commercial account?
No. Order exactly what you need, on your own schedule, with no inventory commitment.
Does AMSOIL offer net-30 terms for businesses?
Yes, commercial accounts can apply for an optional 30-day credit line, or pay by card, check, or bank draft.
What's the difference between a Commercial Account and becoming a Dealer?
A Commercial Account is for in-house use only — lubricating your own vehicles and equipment at wholesale pricing. A Dealer account is built for reselling AMSOIL to others and earning commission. Same wholesale pricing, different purpose.
How is a Commercial Account different from a Preferred Customer account?
Preferred Customer fits a small operation with a few vehicles — up to 25% off retail with a low-cost annual membership. Commercial Accounts are built for higher-volume fleet, farm, or shop use, with wholesale pricing and volume discounts that scale with your annual purchases.
Do you support Canadian businesses?
Yes. Canadian commercial accounts get the same wholesale pricing structure, with free shipping on qualifying orders and pricing shown in CAD.
What documentation do I need to apply?
Basic business information and proof that your company uses lubricants in its own vehicles or equipment. The application itself takes a few minutes.
Can I get help choosing the right products for my specific fleet?
Yes — that's what I'm here for. Call and tell me what you're running (make, model, engine, application) and I'll tell you exactly what fits, including where AMSOIL isn't the right call for a specific use case.
Ready to run the numbers for your fleet?
No obligation — tell me what you're running and I'll give you a straight answer on the savings.
