10W-40 Engine Oil
10W-40 engine oil for older Land Rover petrol and diesel engines where this viscosity and specification are required, together with a Defender 300TDI boxed service kit supplied with filters and engine oil. The current oil product is Ravenol TSi, a high-quality semi-synthetic ACEA A3/B4 oil in a 5L pack.
Start with the engine and the required oil specification, then check the viscosity grade, service quantity and product contents before ordering. A 10W-40 viscosity grade alone does not confirm the correct oil for every Land Rover engine.
