It is a measure of a fluid’s thickness or resistance to flow. For example, honey is thick and water is thin, so honey has a higher viscosity than water. Oil viscosity needs to suit the right ambient temperatures. If it’s too thick when the engine is cold, it won’t move around the engine. And if it becomes too thin when the engine is hot, it won’t give the right protection to the engine parts.\u003C/p\u003E\r\n\u003Cp\u003EOptimising an oil’s viscosity, or thickness, helps maximise energy efficiency while avoiding component wear. Viscosity modifiers increase the viscosity of your oil at high temperature but have little effect on low-temperature viscosity. These enable your oil to flow properly when cold and also to remain thick enough to protect your engine components at high temperatures.\u003C/p\u003E\r\n\u003Cp\u003ELower-viscosity grades of oil such as Shell Helix Ultra, make it easier for your engine to start from cold because they present less resistance to moving parts and hence take less power from your engine. This also means that you get enhanced fuel economy.\u003C/p\u003E\r\n\u003Cp\u003ETo find the right oil viscosity for your engine, check your manufacturer’s guidelines and bear in mind the weather conditions you live and drive in.

Motor oils labelled as ‘part-’ or ‘semi-synthetic’ or ‘synthetic technology’ contains a mixture of these two types. Mineral base oils come from crude oil that is processed in a refinery to separate out the fractions with useful lubrication properties and remove unwanted components such as waxes.\u003C/p\u003E\r\n\u003Cp\u003EUnlike some motor oil manufacturers, Shell makes its own top-class mineral base oils by selecting the best crudes and employing stringent quality control procedures throughout the entire production process.\u003C/p\u003E\r\n\u003Cp\u003ESynthetic base oils give enhanced performance because they are manufactured using a more expensive chemical process than that used in mineral oil production. Because of this, fully synthetic oils like Shell Helix Ultra flow more easily at start-up temperatures, when most wear occurs. They are also more resistant to heat and are more easily protected by antioxidant additives (oxidation is a natural degradation process that occurs in oil over time).
