5W-30 engine oil – for better fuel efficiency and to care for your car
Motorists enjoy a wide range of choices when shopping for engine oil. Manufacturers like Castrol and Mobil offer fully synthetic engine oils in a variety of engine oil classifications, including 5W-30. This all-important combination of letters and numbers represents the engine oil viscosity. Most car manufacturers use SAE viscosity classes, API classifications, and ACEA specifications to indicate the correct oil viscosity for a particular vehicle in its handbook. Motorists should follow this advice to ensure that guarantees are not invalidated. Viscosity is a liquid's resistance to flow, while SAE (the Society of Automotive Engineers) is responsible for devising the system of oil viscosity designations. If you have checked the manual of your vehicle and know that you should use this type of engine oil, you have come to the right place. 123engineoil.co.uk offers fully synthetic 5w30 engine oil products by many top brands.

Top-quality multi-grade engine oils
SAE differentiates between summer oil and winter oil products (single-grade oils) as well as all-season multi-grade oils, which are used by the majority of motorists to care for their car. SAE 5W30 synthetic oil is one such fully synthetic engine oil. The number after the "W" (indicating winter suitability) represents the lowest viscosity of the engine oil at 100 °C, while the number before the "W" represents the lowest temperature at which the oil is still fully pumpable.
