Valvoline MaxLife 10W-40 API SN Plus High Mileage

We supply and install MaxLife 10W-40 API SN Plus High Mileage Engine Oil for vehicles with higher mileage that require extra care and stable protection. This oil is formulated for aging engines where seals, internal clearances, and oil consumption may show wear. Before service, we confirm the correct viscosity and explain clearly what this oil is designed to deliver. The high mileage formula contains seal conditioning additives to help reduce minor seepage and maintain stable lubrication across daily driving temperatures. Its synthetic blend base improves resistance to sludge and deposit buildup, while API SN Plus supports protection against wear, oxidation, and pre-ignition in turbocharged petrol engines. The 10W-40 viscosity provides a slightly thicker oil film, which can help older engines run smoother and quieter. Suitable for many Japanese, Korean, and local petrol vehicles that specify 10W-40, this oil supports consistent performance in city driving and highway use. During service, we inspect the current oil condition and check for visible leaks or abnormal consumption to ensure proper matching and realistic expectations. With correct lubrication, engines may experience smoother acceleration, steadier idle, and reduced vibration. Deposit control and oxidation stability help maintain protection throughout the service interval, supporting dependable daily driving performance. All products follow manufacturer quality standards, and installation is carried out carefully with proper filling and inspection. Warranty covers manufacturing defects only. Book your service in advance so we can prepare the correct volume and ensure a smooth, professional oil change for your high mileage vehicle.
