The 6.75-litre V8 runs on petrol and returns around 10-15 mpg depending on conditions and specification. Early cars use carburettors while some late ones switch to fuel injection. The large tank supports long-distance travel but expect high consumption on spirited drives.
Routine servicing follows a 6000-mile or six-month schedule covering oil changes, filter renewal, fluid checks and lubrication of suspension and steering. Short journeys call for oil changes at half that interval. Specialist tools are needed for hydraulics and brakes.
Safety centres on all-disc brakes with hydraulic assistance shared with the self-levelling suspension, plus seat belts and rear head restraints. US cars gain impact-absorbing bumpers. Handling improves with rack-and-pinion steering. No formal crash-test ratings appear in period records.
Keep the car with regular specialist attention to the hydraulic system, air conditioning and electrics. Parts remain available through Bentley channels and marque specialists. Corrosion checks under the body and proper storage help longevity.
