The synthetic oil used in Mobil 1 gets to work much quicker allowing your engine to reach peak operating efficiency sooner. Mineral oils are a lot thicker, therefore slower making your engine thirstier and less efficient. You could save up to £170 on Fuel per Year if you switch to Mobil 1*.
The Mobil 1 has been designed to look after all modern engines and are therefore more flowing that traditional oils. When you start your engine standard oils can take some time to circulate around the engine, thus allowing friction to occur and can cause expensive wear. With Mobil 1, it gets to work straight away, protecting every part in the engine from wear.
The problems with conventional mineral oils are all the impurities which include unstable hydrocarbons and sulphur affect are forced into the atmosphere. Mobil 1 works hard to reduce as much of these impurities as possible to keep your engine clean and the environment that little cleaner as well.
