Oil is vital for keeping your engine running smoothly. Without the correct oil levels, your engine components wear down prematurely and can fail completely.

Masterparts stocks a range of multifunctional petrol and diesel engine oils. The range includes our in-house brand of synthetic, semi-synthetic, mineral-based and multifunctional oils.

What is multifunctional oil?

Multifunctional oils are all-rounder lubricants designed for use in a wide range of engines, including marine and agricultural engines.

They can be used for multiple lubrication purposes such as transmission and hydraulic systems.

Multifunctional oils use additive technologies, such as viscosity enhancers, to ensure engine lubrication and protection at a range of temperatures.

Understanding engine oil viscosity

Viscosity refers to thickness or resistance to flow.

Engine oil viscosity is important to note because the oil thins when heated and thickens when cooled. Low-viscosity oil will flow easier at lower temperatures. High-viscosity oils are better suited to warmer environments.

Oil viscosity is indicated in the name by a number followed by W (which stands for winter) and then another number (#W-##). The first number is oil flow when it’s cold. The second number after the W is the oil’s viscosity at normal engine operating temperatures.

For example, 5W-30 refers to a low-viscosity oil with an easier flow at start-up temperature. Newer engines tend to use low-viscosity oils. Older engines may benefit from higher viscosity oils.

When you should use multifunctional oils

You should choose a multifunctional oil that can serve the entire fleet when you have a large fleet of vehicles with a variety of engines that have a wide range of mileages, applications and capacities.

By comparison, other high-performance or synthetic oils are often designed for use in a more specific type of engine, function or driving style.
