The Daimler Six runs on petrol with multipoint injection. Fuel tank holds around 80-90 litres depending on exact year. Consumption figures appear in some period data as roughly 13-15 l/100 km combined.
No specific service intervals are stated in available maker pages. Early cars had known electrical and build quality issues that improved later in production.
ABS is standard equipment. Airbags arrived progressively: driver side in later models, passenger later still. No formal crash test ratings are published for this generation.
Keeping the car means watching for common XJ40 electrical gremlins and ensuring the self-levelling suspension and climate system remain in order. Leather and wood need regular care to stay fresh.
