The Land Rover Discovery 4 with a 2.7L diesel engine requires 5.45L of engine oil, the 3.0L diesel engine requires 5.9L, the 4.0L gasoline engine requires 5.7L, the 4.4L gasoline engine requires 7.7L, and the 5.0L gasoline engine requires 8.0L. Introduction to Engine Oil: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³. It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber. It is often referred to as the 'blood' of a car. Engine oil consists of base oil and additives. Engine Oil Performance: Under various conditions, the ability of engine oil to reduce friction, slow down wear, and prevent metal sintering is referred to as the lubricity of the engine. The viscosity of engine oil is an important indicator of its lubricity. The performance of engine oil to ensure easy starting and reliable oil supply under low-temperature conditions is known as the low-temperature operability of engine oil.
I've noticed that my Land Rover Discovery 4 usually takes around 7.5 liters of engine oil, but the exact amount depends on your engine type. Mine is the 3.0 diesel version, and during each oil change, they follow the manual to add 7.6 liters. Oil quantity is crucial—adding too little can cause the engine to overheat and wear out parts, while overfilling can increase oil pressure excessively, leading to leaks or seal damage. I recommend checking your owner's manual directly, as it specifies the precise amount. There might be slight variations for different model years or engine types, like the TDV6, so don't rely on guesswork to avoid issues. During regular maintenance, check the dipstick to ensure the oil level is within the marked range. This practice can extend engine life and save on fuel costs. If you've lost the manual, you can search using your car's VIN code or ask the dealership—don't cut corners by adding oil arbitrarily.
