Land Rover Defender 90 D250 DT306 engines can reliably reach 150,000-200,000 miles with strict adherence to service intervals and quality oil changes. Short-trip urban driving without regular motorway runs may reduce lifespan due to DPF regeneration demands.

Follow 12-month or 12,000-mile service intervals maximum for DT306 longevity
Use only JLR-approved low-viscosity oil to protect turbo and timing components
Regular motorway runs help complete DPF regeneration cycles and reduce oil dilution risk
Address any warning lights immediately to prevent minor issues escalating
