GMC Sierra 4WD
Fuel and energy reference · NRCan rating configuration · service coverage incomplete.
Scope before using a number
Canadian NRCan rating configuration only. Trim, VIN fitment and service applicability are not independently established.
The source model label is preserved exactly, including wheel-size wording where present. 4WD appears explicitly in that label. The NRCan class code PL is a classification, not a country code; the market here is Canada.
The table retains the guide's transmission and fuel codes. No gear-count or component-design claim is inferred from their digits.

What this means for ownership
Which rating applies?
Fuel code D means diesel. Match the light-duty 3.0 L Sierra 4WD A10 row, not the 3.0 L Mud Terrain Tire or AT4X rows. The nearby 5.3 L A10 row instead uses regular gasoline.
Energy for an example 20,000 km year
Applying the guide's combined rating (55% city and 45% highway) gives 1,980 L: 20,000 km × 9.9 L ÷ 100 km. This is a calculation, not another source fact or a prediction. Multiply by your own diesel price per litre for a simple energy-cost scenario; no current price, maintenance cost or depreciation is assumed.
Not established by this source
- Service fluid grades and capacities
- Tyre pressures and replacement fitment
- Towing and payload limits
- VIN/trim-specific applicability
- Maintenance schedule
A missing value is not zero. These gaps do not count toward the existing service-fact publication standard.
