Common EngineSpecification mistakes

Mistakes that pass validation but silently fail to earn rich results or mislead consumers walking the graph. Avoid these and your markup will be ahead of most sites in the wild.

  1. 01

    Power as a bare number

    Wrong
    "enginePower": 85
    Right
    QuantitativeValue with unitCode BHP or KWT

    85 could be bhp, kW, or horsepower; the unit is load-bearing.

  2. 02

    Displacement mixing litres and cc

    Wrong
    "engineDisplacement": { value: 1800, unitCode: "LTR" }
    Right
    Either 1.8 LTR or 1800 CMQ — consistent

    1800 litres would be a marine engine; the mismatch confuses parsers.

  3. 03

    fuelType as a brand name

    Wrong
    "fuelType": "Shell V-Power"
    Right
    "fuelType": "Gasoline"

    Type is the fuel class; brand belongs elsewhere.
