We recommend checking the oil level either before turning on the engine or 5 to 10 minutes after shutting down so you can have all the oil in the oil pan to get an accurate measurement.

Mobil 1 Extended Performance synthetic oil has an even more robust formula that has been proven in extensive field tests to help protect critical engine parts for 25,000 kilometres between oil changes – guaranteed. We’ve selected specific synthetic components to deliver this outstanding level of performance.

You do not need to flush your engine prior to changing to Mobil 1 Extended Performance synthetic oil.

Yes. High mileage engines – those with more than 120,000 kilometres – face a number of potential problems that high mileage oil is specifically formulated to address. Some high mileage motor oils, such as Mobil 1™ High Mileage contain engine oil additives and conditioners that help to combat leaks, sludge and general wear and tear. Mobil 1 High Mileage oils, in addition to providing exceptional wear protection*, offer a lower volatility base oil to maintain protection in higher temperatures and reduce oil burn-off, which could be of value when an engine overheats. High mileage oil helps extend engine life through these additives and conditioners, which makes using a high mileage oil an important investment in your vehicle.

Mobil 1™ Advanced Fuel Economy synthetic motor oils are synthetic motor oils engineered to deliver outstanding engine protection and provide improved fuel economy. The low-friction formulations increase engine efficiency and fuel economy versus those viscosity grades most commonly used. Mobil 1 Advanced Fuel Economy oils outperform conventional oils and meet or exceed the latest industry standards.

First, the performance of Mobil 1 motor oil is more robust, especially in terms of low-temperature pumping and flow. High-temperature stability leading to protection against deposits is also superior. These attributes translate into less engine wear, which helps keep your engine running like new, and a long engine life. Conventional oils lack the performance of synthetic motor oils in the areas of low-temperature performance and high-temperature oxidation stability. Mineral base stocks used in conventional motor oils also contain significantly more impurities, such as aromatics and other undesirable contaminants that cannot be completely removed by conventional refining of crude oil.
