Article: https://yenra.com/biodiesel-vehicles/

PURPOSE
Use this record to match a supplied fuel to one identified vehicle or fleet group. Obtain written equipment approval and fuel documentation; mark missing information as unresolved. This record does not authorize a fuel blend or provide blending instructions.

EQUIPMENT
Vehicle / model year / engine identifier / market:
Owner or engine manual version and date:
Later manufacturer fuel bulletins:
Maximum approved biodiesel content:
Required finished-fuel standard and grade:
Temperature restrictions:
Required maintenance changes:
Warranty terms and service contact:
Written clarification for any ambiguity:

SUPPLIED FUEL
Supplier / product / batch or delivery / date:
Declared biodiesel fraction by volume:
Renewable diesel or other components:
Applicable finished-fuel specification and edition:
Quality certificate or supplier declaration:
Cold-weather suitability and source:
Invoice and delivery record location:

U.S. SPECIFICATION CONTEXT
ASTM D975 addresses diesel fuel, including up to 5% biodiesel.
ASTM D7467 addresses B6-B20 blends.
ASTM D6751 addresses B100 biodiesel blendstock.
Check the current standard and exact manufacturer requirements.
Renewable diesel is a hydrocarbon fuel; biodiesel has ester chemistry.
Record the complete supplied product and any biodiesel fraction.

FICTIONAL APPROVAL EXAMPLE
An engine has a documented maximum of B20. The offered fuel is B30.
It exceeds the documented limit. Obtain compliant fuel or explicit
revised approval before use. A price or quality claim does not change
the engine's documented limit.

OPERATING PLAN
Expected lowest ambient exposure and duration:
Supplier guidance for those conditions:
Storage volume and anticipated turnover:
Water / tank / quality inspection responsibility:
Extended-storage testing if required:
Filter observation and maintenance plan from service provider:
Symptoms and conditions to record if operation changes:
Retain fuel identity and service records for diagnosis.

MATCHED-DUTY COST COMPARISON
Keep route, payload, conditions and distance units consistent.
Fuel price per gallon:
Measured miles per gallon:
Cost per mile = price per gallon / miles per gallon.
Fictional fuel A: $4.00 / 10.0 = $0.400 per mile.
Fictional approved fuel B: $3.90 / 9.5 = about $0.411 per mile.
Lower price per gallon can still yield higher fuel cost per mile.
Use repeated representative observations; these are invented rates.

DECISION
Written compatibility complete:
Supply documentation complete:
Operating and maintenance plan complete:
Emissions claim boundary / blend / engine / study, if used:
Open question / responsible person / due date:
Approved procurement decision and evidence location:
