0W-30 engine oil
Your engine oil keeps all the parts of your engine lubricated to reduce friction and prevent any damage to your engine. However, different engine oils have different efficiency and fluidity at high and low temperatures. You can tell a lot about an engine oil’s performance at different temperatures by its viscosity grade.
A viscosity grade has two parts to it, with the whole grade looking like ‘XW-XX’, e.g. 0W-30. The ‘W’ stands for winter, and the numbers relate to engine oil performance in high and low temperatures.
- The first number before the W is for the oil’s flow at low temperatures. Lower numbers here mean the oil will thicken less during cold weather.
- The two numbers after the W relate to how resistant the oil is to thinning at high temperatures over 100 degrees Celsius.
Modern engines benefit more from lower grade viscosities as they let your engine oil perform more efficiently and help improve your fuel economy. Older vehicles may require higher grade viscosity.
Did you know...?
You get your engine properly lubricated faster in winter with thin engine oils that thicken less in the cold, whereas in summer you may be better off with thick oils that are less likely to thin in higher temperature conditions.
0W-30 synthetic engine oils
When you use 0W-30 engine oil, you’ll have oil that can flow as 0 weight in cold temperature while also offering protection in higher engine temperatures due to the 30 weight viscosity. The Mobil 1™ ESP 0W-30 engine oil provides your engine with high-quality protection from the moment you start your engine and maintains that protection as your engine heats up to high temperatures.
