Free-flowing Mobil 1 starts protecting as soon as you start your engine, making it the perfect choice if most of your driving involves short journeys. If most of your driving consists of short journeys - the quick trip to work, the school run, or down to the shops - your engine hardly has time to warm up before it is turned off again. To save engine wear, you need outstanding cold start protection. In tests, it has been proven that Mobil 1 still flows freely at temperatures as low as negative 40°C and it can reach all moving parts of the engine 15 seconds faster than some conventional oils at start-up. That means Mobil 1 starts protecting your engine straight away, saving it from a great deal of punishment, and saving you money on fuel and maintenance costs. And, of course, it also means more reliable starting, even on the coldest mornings.
