KLEENOIL Engine Applications

CASE STUDY LAND ROVER DEFENDER 300TDI – EXTENDING ENGINE LIFE WITH KLEENOIL

EXTENDING ENGINE LIFE THROUGH SUB-MICRON OIL FILTRATION

The Land Rover 300Tdi Defender in this case had been driven intensively, covering nearly 25,000 miles in just 18 months . Like most diesel workhorses, it required oil changes every 6,000 miles , which created three key issues:

Rising servicing costs Engine wear risk from residual contaminants Frequent downtime and oil waste

The owner actively sought a long-term solution — not just to reduce servicing frequency, but to protect the engine internally and preserve oil quality over extended use. Confidence in Kleenoil came from operators across the commercial vehicle sector. In one reported case, a DAF fleet truck fitted with a Kleenoil bypass system from new ran for over 1 million miles on its original engine without a rebuild — a level of durability unheard of with standard filtration and servicing alone. This case documents the results of applying the same technology to the Land Rover Defender.
