Cadillac manufacturer position
Cadillac luxury vehicles are not part of the mainstream NZ-new range but appear as grey imports and ex-fleet vehicles. Petrol and diesel variants require OEM drain procedures; high-pressure diesel injection is sensitive to petrol contamination.
Fuel system notes
- Confirm powertrain before drain—Escalade and full-size SUVs may be petrol or diesel.
- Lyriq, Optiq, and Escalade iQ are electric—misfuel pages focus on petrol/diesel models.
- GM capless systems still use module access for contamination recovery.
