What type of engine oil is used in the BMW 740?
2 Answers
The BMW 740 uses 0W-30 engine oil. Below is relevant information about the BMW 740: 1. Introduction: The BMW (BMW) 740Li is a high-end luxury sedan produced by the German BMW company. It belongs to the "BMW 7 Series" and is exclusively manufactured in Germany. 2. Powertrain: The new 740Li is equipped with a 4.0-liter V8 engine, which is an upgrade from the previous 3.6-liter V8 engine. The facelifted new 7 Series features a more approachable exterior design. In addition to incorporating BMW's Double-VANOS dual overhead camshaft variable valve timing system, the new engine also utilizes the continuously adjustable Valvetronic electronic valve drive mechanism, significantly reducing fuel consumption and emissions. The engine delivers a maximum power output of 225 kilowatts and a maximum torque of 390 Newton-meters, accelerating from 0 to 100 km/h in just 4.6 seconds. The new i-Drive system has also been upgraded, offering faster and more convenient operation, though it remains the most complex system across all BMW models.
I've been driving a BMW 740 for many years, and experience tells me it performs best with 0W-30 full synthetic oil. BMW officially recommends this grade because it protects engine lubrication at high RPMs. I use the Shell brand, which delivers smooth acceleration and stable fuel consumption. The manual emphasizes compliance with BMW LL-01 standards to prevent engine carbon buildup and protect turbocharger lifespan. In cold climates, prioritize 0W for quicker starts; in hot regions, use 5W-30 to prevent overheating. Never switch to cheaper oil casually—I once tried mineral oil and experienced unstable idling, which was resolved only after switching back to synthetic oil at a professional shop. For maintenance, check oil levels every 8,000 km, ensuring it remains clear and free of impurities to extend the vehicle's service life.
