What makes Mobil 1™ superior to our conventional motor oil?
First, the performance of Mobil 1™ 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.
Will the use of Mobil 1™ void my new car warranty?
With the exception of the Mazda rotary engine (Mazda does not recommend any synthetic oils), Mobil 1 will not void new-car warranties where an American Petroleum Institute (API) certified oil is recommended. Mobil 1 meets or exceeds API and International Lubricant Standardization and Approval Committee (ILSAC) motor oil service requirements of all new-car manufacturers, both import and domestic. If in doubt, always check your vehicle owner’s manual or contact the vehicle manufacturer.
Is it true that new engines need break-in periods using conventional motor oil?
That is a myth. In the past, engine break-in was necessary to remove metal flashing or any other abrasive material left inside the engine after machining, as well as to allow the valves and rings to “seat” properly. Today’s engines are built with much tighter tolerances and much improved machining, and under much cleaner conditions compared to the engines of 10 or 20 years ago. Current engine manufacturing technology does not require a break-in period using petroleum-based motor oils.
How often should I change the oil if I’m using Mobil 1™?
Oil change intervals can be as short as 3,000 miles or as long as 15,000 miles on some new cars. We recommend that you follow the oil and filter change frequencies shown in your owner’s manual, especially during the warranty period. With the high-performance reserves of Mobil 1, you can have the confidence to go the full mileage or time frame recommended by the vehicle manufacturer. Mobil 1 is especially suitable for the latest vehicles with extended drain intervals or vehicles with oil monitoring systems that vary oil drain intervals.
