Purpose: compare a household travel baseline with a proposed change.
Use one distance unit and one fuel-volume unit throughout. Keep measured data separate from assumptions. For electricity or another fuel, create a separate record in the appropriate native units.

Vehicle / period / data source:
Trips served and passengers where relevant:
Baseline total distance (miles):
Baseline total fuel (gallons):
Measured baseline MPG = total miles / total gallons:
Proposed change and feasibility:
Scenario distance (miles):
Scenario MPG and evidence:
Scenario gallons = scenario miles / scenario MPG:
Gallons saved = baseline gallons - scenario gallons:
Percent saved = gallons saved / baseline gallons x 100:
Comparison period / weather / route differences:
Actual follow-up distance, fuel and result:

Fictional example: 12,000 miles / 30 MPG = 400 gallons. 10,800 / 30 = 360 gallons. 10,800 / 36 = 300 gallons. Combined saving = 100 gallons or 25%. In this sequence distance saves 40 gallons and consumption improvement saves another 60 gallons. These are invented inputs, not promised savings.
