Motor Oil

Motor oil explained

For industries reliant on motorised vehicles, be it haulage, transport or racing, using a motor oil to prevent problems before they arise is essential. Maintaining optimum performance increases productivity, thereby reducing any costs long term and improving the lifespan of vehicles. While motor oil was traditionally a simple base oil with a selection of additives, it has evolved into a complex lubricant with several performance benefits, and is integral to the output and efficiency of modern vehicles.

What is motor oil?

Motor oil is primarily used for lubricating the components of a vehicle’s engine. This lubrication reduces wear and tear, allowing engines to work more efficiently and last longer. Motor oil is produced from a base oil, acting as the carrier oil, with a number of additives then included to target specific functions within the engine. This base oil is roughly 70% of the overall mixture with additives forming the remainder. 

During the combustion process, these additives help to cool the engine, thus reducing excess friction. They also protect the emissions system and combat acid corrosion, helping to increase the longevity of your vehicle. Antioxidants allow engines to perform well across a range of temperatures and dispersant and detergent additives act to clean the engine and stop deposits like dust, sludge and dirt building up. To maximise the capabilities of motor oil, anti-foam additives are included to prevent oils from forming air bubbles which can reduce the lubricant qualities and prevent motor oil from working as effectively. 

Motor oil or engine oil?

Motor oil and engine oil are primarily the same thing. The two terms are used to refer to oil that is added to your vehicle’s engine to help it perform better. Both motor oil and engine oil are lubricants made from combining a base oil, usually from a crude oil, with a number of different  additives. The priority is choosing the correct motor oil for your vehicle. We distribute motor oil from premium manufacturers like Shell and Castrol, and you can find more advice and guidance on our partner pages.

Better performance. Better business.

Motor oil is beneficial for all modern vehicles, be that domestic cars or business fleets. Using motor oil for business helps manage the total cost of ownership, with the long term benefit of reduced repair costs and vehicles that outlast the competition. Private hire firms, couriers and both LGV and HGVs will perform significantly better with the aid of a top quality motor oil. Motor oil use is, of course, prevalent in motor sport and illustrates the advantages of using a motor oil that specifically targets common engine problems. These high performance vehicles are an advert for motor oil and demonstrate the extended benefits of using it as part of your vehicle’s regular maintenance routine. 

Benefits of motor oil

The engine boosting additives included in motor oil work to target specific challenges. The benefits of using motor oil include:

Reduces corrosion Corrosion inhibitors help to neutralise acids that can weaken and corrode engine parts.

Prevents damage – Damage from heat and friction is targeted by anti wear additives and friction modifiers for an engine that lasts longer.

Enhanced efficiency – Fuel consumption is increased when friction occurs within an engine. With motor oil minimising the effect of friction, fuel consumption is more economical, and emissions are also reduced.

Improves engine health As well as cleaning and preventing the build up of sludge and dirt, motor oil creates a protective layer between engine components like pistons and cylinders. 

Stabilises heat production – Motor oils help to release heat and work in tandem with coolant products during the combustion process.

Motor Oil FAQs

Using motor oil in your vehicle engine is an effective and easy way to improve the performance and engine capability. Not only does it improve fuel efficiency and reduce damage, but it acts alongside coolants to release heat, and cleans dirt and deposits from engine parts.

The motor oil you need will depend on the vehicle in question and its use. Using a top quality motor oil from a premium manufacturer like Shell or Castrol will ensure you are getting the absolute best product for your engine.

Each motor oil has its own benefits. Leading manufacturers design and produce motor oils that have been rigorously tested to provide maximum results. When choosing a motor oil, though the cheapest one may seem attractive, opting for a high quality product will result in cost savings over time and achieve far better value for money.

For a healthy engine and to get the most from your vehicles, particularly business fleets, it’s essential to use motor oil. Paying for costly repairs or damages can be avoided by regularly checking and changing the motor oil.

Motor oil and engine oil are, in basic terms, the same thing. They are a base oil combined with a number of additives. This lubricant oil is then added into an engine and carries out several functions, such as cooling, cleaning and protecting to both increase output and extend the life of your vehicle.
