23909459 Oil | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta VDS-4.5 engine oil, SAE 15W-40, in a 1 litre bottle weighing 0.93 kg. VDS-4.5 is the heavy-duty grade: high-quality base oils and additive components give improved engine cleanliness and protection against piston deposits, and the 15W-40 is fully backward compatible with all older Volvo Penta diesel engines. It is also recommended for certain petrol engines, which the operator's manual for the engine settles. It consolidates 23571951 and 23909453, so an order placed under either now resolves to this bottle.

🔌 Function

Lubricates the engine's moving parts, carries heat away from them, holds soot and combustion products in suspension and protects internal surfaces against corrosion.

⚠️ Common Signs of Failure

• Oil gone black and thin well before the service interval is due
• Oil pressure low or slow to build when hot
• Level dropping between services
• Milky or creamy oil, pointing at coolant getting in
• Sludge or varnish on internal surfaces at service

🛠️ Service Notes

• The VDS-4.5 grade matters as much as the 15W-40 viscosity - a lower specification oil can shorten the approved service interval
• This is the 1 litre top-up bottle; the same oil comes in 5 litre and 20 litre containers as 23909460 and 23909461
