How Many Liters of Engine Oil Does a Discovery 4 Require for Maintenance?
2 Answers
Discovery 4 maintenance requires 6 liters of engine oil. Introduction to Discovery 4: Produced by Land Rover in 2016, it is a sport utility vehicle featuring a 3.0TV6 engine, an 8-speed automatic transmission, and a 5-door, 5-seat configuration with front-mounted four-wheel drive. Types of Engine Oil: Based on their source, engine oils are categorized into three types: conventional mineral oil, synthetic oil, and nano-ceramic oil. Conventional oil contains significantly more impurities, sulfur, reactive and unstable hydrocarbons, and other harmful contaminants that cannot be fully removed through traditional crude oil refining. Synthetic oil offers superior lubricity, lower friction resistance, better oxidation resistance, and stronger cleaning properties compared to mineral oil. Its drawbacks include slightly poorer low-temperature fluidity and heat resistance than mineral oil. Nano-ceramic oil is formulated by adding nano-ceramic additives and other compounds to base oil, making it suitable for lubricating systems in vehicle internal combustion engines. Generally, the more advanced the oil type, the better its performance, though this also corresponds to a higher price. Engine Oil Grade Selection: According to the API standard classification, grades starting with 'S' followed by letters E, F, G, H, G, L, M, N indicate progressively higher quality levels and better performance as the sequence advances.
I remember when changing the oil for my Land Rover Discovery 4, it usually takes around 7.5 liters. I've done the maintenance myself a few times, and the engine is the diesel 3.0L model. The manual states 7.6 liters, but if you replace the filter as well, you need to add about 8 liters to get it just right. The key is not to guess the quantity—too little oil leads to faster engine wear, while too much increases fuel consumption and can cause leaks. After each oil change, I start the car for a few minutes, then turn it off and wait a while before checking the dipstick to ensure the level is between the high and low marks. Honestly, Land Rovers are quite 'thirsty' for oil, especially large SUV engines like this one. I recommend buying a bit extra oil, such as an 8-liter container, and storing the remainder for next time. Also, pay attention to seasonal changes—thinner oil in winter provides better lubrication. If you're doing it yourself, remember to wear gloves for safety. Regular maintenance is crucial—don’t skimp on oil costs, as the engine is far more expensive.
