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 mostly in the label, the payment system at fleet stops, and how cold-climate stations rotate blends through winter.

  1. 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. 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. 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. 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)

The U.S. labeled-blend footprint concentrates heavily in the Midwest and on the West Coast. If you're routing through the Southeast, the Mountain West, or interior New England, plan stops before you start.

Most reliable trucking corridors

  • I-80 east-west — particularly through Iowa and Nebraska, where biofuel mandates and tax incentives create dense truck-stop B20 availability.
  • I-35 north-south — Texas through Oklahoma, Kansas, Iowa, and Minnesota, anchored by Iowa's high station density.
  • I-94 / I-90 — Minnesota across the upper Midwest into Washington.
  • I-5 along the West Coast — California and Oregon Renewable Fuel programs maintain coverage from San Diego to the Canadian border.

What B20 actually costs at the pump

Retail biodiesel pricing tracks petroleum diesel closely — closer than most people expect. The exact spread depends mostly on your state's biodiesel tax treatment.

Federal context: the federal Biodiesel Tax Credit (now the Clean Fuel Production Credit, IRC §45Z) flows through the supply chain and dampens retail spreads. State programs that meaningfully shift pump prices include Illinois (sales-tax exemption on B11+ blends), Minnesota (B20 mandate normalizing supply), Iowa (producer credits), and California (Low Carbon Fuel Standard credit value).

For current numbers, AFDC publishes the Clean Cities Alternative Fuel Price Report on a quarterly cadence. The pattern below reflects the long-running historical relationship; pull the most recent report for live pricing.

Petroleum diesel #2 (national avg) baseline
B20 (national avg vs diesel) ±$0.05–$0.20/gal
B20 in Illinois (sales-tax exemption) often below diesel
B20 in Iowa, Minnesota at or below diesel
B100 (where retail-available) +$0.50–$1.00/gal
Fleet contract pricing (varies) often beats retail

Pump labels and what they mean

The FTC's Fuel Rating Rule (16 CFR Part 306) sets the exact wording on biodiesel pump labels. They're intentionally bland — yellow background, black border, all-caps — but the wording is precise. Here are the four formats you'll see at a U.S. pump.

DIESEL FUEL

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.

BIODIESEL BLENDCONTAINS 6 TO 20 PERCENT BIODIESEL

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.

BIODIESEL BLENDCONTAINS MORE THAN 20 PERCENT BIODIESEL

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.

BIODIESELCONTAINS 100 PERCENT BIODIESEL

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.

Frequently Asked Questions

Get answers to common questions about biodiesel stations and refueling

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 blends, with hours and directions. Many additional stations sell low-level blends (B5 and below) without separate labeling, since ASTM D975 lets up to 5% biodiesel be sold as standard diesel.

How many biodiesel stations are there in the US?

About 1,967 public retail stations carry B20 or higher (AFDC, April 2026). Illinois leads with 487, followed by California at 453, Iowa at 362, and Minnesota at 284. Coverage thins quickly outside the Midwest and West Coast, though most highway corridors have at least a few options.

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 from the manufacturer. Our B20 guide covers the OEM positions in detail.

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 biodiesel blend at retail. B100 is pure biodiesel under ASTM D6751, used mostly in dedicated fleets with seasonal management. See the full blends comparison for engine compatibility, energy content, and cold-weather notes.

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. The federal Biodiesel Tax Credit and state-level programs in Illinois, Iowa, and Minnesota narrow the gap. Fleet contracts and bulk pricing can differ from posted retail prices.

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 8% less energy per gallon (roughly 119,550 BTU vs 128,488 for petroleum diesel) and shows a noticeable fuel-economy drop in vehicles approved to run it.

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 fuel tank for more than one month. Bulk biodiesel storage usually requires antioxidant additives, water-bottom monitoring, and tighter housekeeping than diesel.

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 also has detergent properties that can dislodge old deposits — which is why Cummins requires shortened fuel-filter intervals (half the normal interval) for the first two filter changes after switching to B20. After the initial cleaning period, intervals return to normal.
