Which blend can I use?
The number after the B is the percentage of biodiesel. Three blends cover almost everything you'll see at a U.S. pump.
Already in your tank
Up to 5% biodiesel is sold as ordinary diesel with no label. Every diesel engine is approved for it.
B5 explained →
B20The one on the map
20% biodiesel. Approved by Ford, GM, Ram/Cummins and most heavy-duty makers on modern engines. What nearly every station here sells.

B100Pure biodiesel
B99/B100 is rare at retail and needs the right engine, seals and climate. Mostly fleets and dedicated enthusiasts.

What it's like to fill up with biodiesel
If you've fueled a diesel before, biodiesel feels almost identical at the pump. The differences are in the label, the payment system at fleet stops, and how cold-climate stations rotate blends through winter.
-
1
Read the pump label first
The FTC's Fuel Rating Rule (16 CFR Part 306) requires biodiesel-blend pumps above B5 to display the blend percentage in a yellow-and-black label. "BIODIESEL BLEND — Contains 6 to 20 percent biodiesel" means a B6–B20 fuel meeting ASTM D7467. "BIODIESEL — Contains 100 percent biodiesel" means B100 meeting ASTM D6751. No label? You're getting standard diesel — which under ASTM D975 is allowed to contain up to 5% biodiesel without separate marking.
-
2
Use the same nozzle as standard diesel
Biodiesel nozzles are identical to standard diesel — same diameter, same fittings, same flow rate. No adapter, no special procedure. That's true at every blend level from B5 through B100.
-
3
Expect different payment options at fleet stops
Retail biodiesel stations take the usual credit cards. Fleet-focused biodiesel terminals — often co-located at truck stops, ag co-ops, or municipal yards — typically run on Pacific Pride, CFN, or Wright Express cardlock systems. If your truck takes a fleet card, the locator above tags those stations in the result list.

4
Watch for seasonal blend rotation
In Minnesota, Iowa, and other cold-climate states, retail B20 pumps usually drop to B5 or B11 for the coldest weeks of winter — typically late December through early February. The pump label updates with the seasonal change. Below 0°F even straight petroleum diesel needs winterization, so this rotation isn't unique to biodiesel; it just happens earlier with biodiesel because of its higher cloud point.
Where biodiesel coverage is good (and where it isn't)
Labeled biodiesel is concentrated in the Midwest and on the West Coast. If you're routing through the Southeast, Texas, the Mountain West or New England, plan stops before you leave.
Most reliable trucking corridors
- I-80 — especially through Iowa and Illinois, where tax incentives make B20 common at truck stops.
- I-35 — Missouri through Iowa into Minnesota. South of Kansas City, coverage drops off fast.
- I-94 / I-90 — Minnesota across the upper Midwest.
- I-5 — California and Oregon clean-fuel programs keep coverage steady; Washington is much thinner north of Vancouver.
Pump labels and what they mean
The FTC's Fuel Rating Rule (16 CFR Part 306) sets the exact wording on biodiesel pump labels. Here are the four you'll see at a U.S. pump.
Standard ULSD diesel under ASTM D975. Allowed to contain up to 5% biodiesel without separate disclosure since 2008. No label change required — which is why most U.S. diesel pumps are already low-blend biodiesel and don't advertise it. See the B5 explainer for what this means in practice.
B6 through B20 under ASTM D7467. The exact percentage may shift inside this range from week to week depending on what came off the rack at the supplying terminal. Most labeled blends in the U.S. fall in this band.
Less common. Above-B20 blends that aren't pure B100 — typically B30 or B50 — show up in fleet specialty applications and a handful of retail pilots. OEM warranty coverage drops sharply above B20.
Pure B100 under ASTM D6751. Rare at retail; mostly fleet depots, transit yards, and a small number of dedicated public stations. Engine compatibility is much narrower than B20 — check the OEM's specific position before fueling.
What B20 actually costs at the pump
Retail biodiesel tracks petroleum diesel closely — closer than most people expect. The spread depends mostly on your state's tax treatment.
The federal Clean Fuel Production Credit (IRC §45Z, successor to the biodiesel blenders credit) flows through the supply chain and dampens retail spreads. State programs that shift pump prices include Illinois (sales-tax exemption on higher blends), Minnesota (B20 summer mandate), Iowa (retailer credits and a lower excise rate) and California (Low Carbon Fuel Standard credits).
For current numbers, AFDC publishes the Clean Cities Alternative Fuel Price Report quarterly. The pattern here reflects the long-running relationship, not today's price.
Multi-year pattern from the AFDC Alternative Fuel Price Report. Spreads narrow when feedstock (soy oil, used cooking oil, tallow) gets cheaper and widen when it doesn't.
Biodiesel FAQ
Where can I buy biodiesel near me?
Use the station locator at the top of this page. Enter a ZIP code or city and the map shows the nearest public stations selling B20 or higher, with hours and directions. Many more stations sell low-level blends (B5 and below) with no separate label, because ASTM D975 lets up to 5% biodiesel be sold as standard diesel. For a full list by state, see biodiesel stations by state.
How many biodiesel stations are there in the US?
About 1,997 public retail stations carry B20 or higher (AFDC, September 2026). Illinois leads with 490, followed by California at 452, Iowa at 399, and Minnesota at 284. Coverage thins quickly outside the Midwest and West Coast.
Can my diesel vehicle run on biodiesel?
Most modern diesel engines accept B20 or lower without modification. Ford approves up to B20 in all Power Stroke engines. Cummins approves B20 in on-highway ISX, ISM, ISL, ISV5.0, and ISB engines built after January 2007. Older engines, especially those with rubber fuel-system components, may need a check with the manufacturer. Our truck compatibility guide goes brand by brand.
What's the difference between B5, B20, and B100?
The number is the biodiesel percentage. B5 is 5% biodiesel, sold as ordinary diesel under ASTM D975. B20 is 20% biodiesel under ASTM D7467 — the most common labeled blend at retail. B100 is pure biodiesel under ASTM D6751, used mostly in dedicated fleets. See the full blends comparison.
How much does biodiesel cost compared to diesel?
B20 retail prices usually fall within a few cents of conventional diesel — sometimes lower, sometimes higher, depending on feedstock costs and local incentives. State programs in Illinois, Iowa, and Minnesota narrow the gap. The locator doesn't show live prices; the DOE's quarterly Alternative Fuel Price Report is the best public source for regional averages.
Who sells biodiesel in bulk, or B99/B100?
Retail pumps almost always sell B20. For B99 or B100, or for bulk delivery to a farm or fleet tank, you'll usually deal with a fuel distributor rather than a gas station. Only about two dozen public B99/B100 pumps exist nationwide (nine of them in Hawaii) and they show up in the locator; our B100 page explains how to find suppliers. Biodiesel plants generally sell by the truckload to distributors, not to the public.
Will biodiesel hurt my fuel economy?
B20 contains about 1–2% less energy per gallon than petroleum diesel, which most drivers don't notice. B100 contains about 7–8% less (roughly 119,550 BTU vs 128,488 for petroleum diesel) and shows a measurable drop. More in biodiesel vs diesel.
Is biodiesel safe to store long-term?
Less so than petroleum diesel. Biodiesel oxidizes faster, absorbs water more readily, and can support microbial growth at the fuel-water interface. Ford specifies not storing B20 in a vehicle's tank for more than one month. Bulk storage usually calls for antioxidant additives and water-bottom monitoring.
Is biodiesel better for my engine?
Biodiesel has higher lubricity than ultra-low-sulfur diesel, which can reduce wear in injectors and fuel pumps. It's also a mild solvent that loosens old deposits — which is why Cummins calls for fuel-filter changes at half the normal interval for the first two changes after switching to B20. After that, intervals return to normal.
