What type of engine oil is used in the Volkswagen Tharu?
3 Answers
Volkswagen Tharu uses 5W40 engine oil. Functions of engine oil: It separates the relatively sliding parts to reduce wear, carries heat back to the oil tank and dissipates it into the air to assist the radiator in cooling the engine. It circulates carbon deposits, sludge, and worn metal particles from engine components back to the oil tank, flushing away contaminants generated on the working surfaces of parts through the flow of lubricating oil. Precautions for engine oil usage: Engine oil should be selected according to the engine's requirements, choosing oil that matches the engine. Multi-grade oil is recommended as it offers advantages such as fuel efficiency, long service life, and high efficiency, providing better protection for the engine. The oil level should be slightly below the mark on the dipstick and not overfilled.
I've been driving my Volkswagen Tharu for five years, using 5W-40 synthetic oil that meets the VW 502 00 standard, which is perfect for older models. This oil performs stably in both scorching summers and freezing winters, providing excellent engine lubrication and reducing noise. I change the oil every 10,000 kilometers, and I always remember to check the dipstick. If the oil turns black or has an unusual odor, it's time for an early change. Stick to big brands like Shell or Mobil to avoid counterfeit products. Using the right oil ensures smooth acceleration, extends the vehicle's lifespan, and keeps costs low. Before each maintenance, I check the manual to confirm—newer models might require VW 504 00, but my experience shows 502 is sufficient. Don’t neglect regular maintenance, or you’ll risk component wear and higher repair costs.
As a mechanic with over a decade of experience in auto repair shops, I often recommend Touareg owners to use 5W-30 synthetic oil with VW 502 00 or 504 00 certification. Especially for new vehicles equipped with particulate filters, 504 certification is essential to ensure emission compliance. Synthetic oil offers superior fluidity, effectively protecting the turbocharging system from high-temperature damage. Never opt for mineral oil to save costs, as it can lead to engine carbon buildup and accelerated wear. The recommended maintenance interval is every 8,000 to 10,000 kilometers for oil changes, along with regular oil level checks. If the oil appears dark or thickened, replace it immediately to prevent malfunctions. Volkswagen engines are highly sensitive to oil quality, so choosing products with high API certifications, such as Mobil 1, is more reliable. Regular maintenance also contributes to better fuel efficiency.
