How to Choose Oil for K9K
- Viscosity must match specification — using the wrong viscosity grade is not acceptable. Only 5W-40 is approved for K9K.
- Check the approval code on the label — the can must show Renault RN0720 / ACEA C4 compliance. Regular oil with an incorrect approval may damage the engine.
- Volume — when changing with a new filter, you need 5.0 L. Check the oil level with the dipstick 5 minutes after filling.
- Do not mix grades — if topping up, use the same viscosity and specification.
Consequences of Using the Wrong Oil
- Oil with a wrong approval for a diesel engine can clog the DPF filter (diesel) or cause excessive oil consumption.
- Too thin oil (e.g. 10W-40 instead of 5W-40) accelerates timing chain/belt and crankshaft bearing wear.
- Too thick oil makes cold starting difficult and increases fuel consumption.
