Mobil 1 Engine oil

Oil is the blood of your car. If the wrong kind is used, the engine is at risk of increased wear and corrosion. Formation of blockages can also lead to engine seizure. By putting our oils in the engine, you can carry on motoring with confidence and experience the feeling that your car has just been serviced – all for less than the cost of a tank of fuel.

Keeping engine components clean is essential as it keeps them in good condition. If your engine components are dirty, oil may not be lubricating and protecting the engine properly. Dirt build-up can also lead to premature engine damage. Our engine oils are designed to clean and protect engines for improved performance.

In many ways:

1. Cleaning the engine

Our oils are designed to clear away dirt, debris and deposits from engine components and to prevent blockages in important oil ways. The oil helps to lock up the dirt and render it harmless until it is removed at the next oil change.

2. Minimising friction and wear

our oils form a protective film over your engine components and have special additives that act between the moving surfaces to prevent contact and reduce drag. This helps your engine to operate as quietly and effectively as the designers intended.

3. Removing heat

Our oils carry heat away from hot areas, such as around the piston rings where the temperature can reach up to 320°C, and redistribute it around the engine.

4. Preventing corrosion and rust

Our oils help to protect your hard-working engine components from corrosion beyond the normal oil-change interval. Benchmarking studies show that Shell Helix oils provide best-in-class protection and help to extend your engine’s life and avoid some expensive repairs.

Engine oils are made up from three important ingredients – base oils, viscosity modifiers and performance additives. These are carefully selected and skilfully blended to enable the oil to provide maximum engine protection.

You should change your oil and filter at or before the end of oil-change intervals indicated by your vehicle manufacturer. These are based on distance travelled or time. Regular oil changing helps to keep your engine oil in good condition and provide the best protection for all of your engine components.

Used oil can pollute the environment and should never be poured down the drain. In many markets it is also illegal to do this. Instead, take your waste to an official oil-disposal or recycling bank (these are often located at local refuse collection points). Alternatively, ask your local authority recycling officer for guidance.

Not changing your oil on a regular basis can significantly reduce the level of protection provided against engine wear. Engine oil acts as a reservoir for all kinds of by-products that form when the fuel burns, including soot, sludge, water and acidic material, as well as unburned and partially burned fuel. At the same time, the stress placed on the oil during engine operation gradually depletes the components that determine the oil’s performance. Refreshing the oil on a regular basis ensures that the right balance of components is present in the oil.

It also removes waste materials that might otherwise result in increased deposit formation, corrosion of metal components and increased wear.

If you simply keep on topping up your oil, you put more stress on the older oil that remains in the engine. And this stress issue has become worse in recent years as lighter, modern engines now run with about 25% less oil in their sumps. Our oils have a powerful ability to clean up your engine components and goes on keeping engines clean through to the next oil change.

All engine oils are made of base oils and additives. A synthetic lubricant contains more highly refined base oils than conventional mineral oils, offering you superior protection and performance. Synthetic engine oils provide a variety of benefits that keep your engine running at optimal performance for years, such as help to prevent wear, keep an engine clean, flow easily, maintain viscosity, prevent rust and reduce friction.

All engine oils are made of base oils and additives. Fully synthetic engine oils contain 100% non-conventional, high-performance fluids. Semi-synthetic engine oils (also called "blends") contain a smaller percentage of these high-performance fluids in combination with conventional mineral oil. Mobil 1 is a fully synthetic motor oil.

You get an unsurpassed level of engine protection. Back in 1974 when Mobil 1 was launched, it was the first widely available automotive synthetic lubricant on the market. Today, there are others but Mobil 1 is still universally acknowledged to be the most advanced.

Furthermore we also have multiple decades of experience in F1 that, partly thanks to mobile lubricants, has advanced so much the latest years. 

Free-flowing Mobil 1 starts protecting as soon as you start your engine, making it the perfect choice if most of your driving involves short journeys. If most of your driving consists of short journeys - the quick trip to work, the school run, or down to the shops - your engine hardly has time to warm up before it is turned off again. To save engine wear, you need outstanding cold start protection.

In tests, it has been proven that Mobil 1 still flows freely at temperatures as low as negative 40°C and it can reach all moving parts of the engine 15 seconds faster than some conventional oils at start-up. That means Mobil 1 starts protecting your engine straight away, saving it from a great deal of punishment, and saving you money on fuel and maintenance costs. And, of course, it also means more reliable starting, even on the coldest mornings.

Outstanding protection even at the most extreme temperatures makes Mobil 1 ideal if most of your driving is high speed motorway cruising. If you often drive long distances at high speeds, your engine will get extremely hot. And, needless to say, fuel economy will be a matter of great importance to you.

The Million Mile Test and the Drive Around the World proves that no matter how long the journey, Mobil 1 can virtually eliminate engine wear; keeping your engine in almost the same condition as the day it was fitted. That means your engine won't only continue to perform at its peak, it will also run more efficiently and use less fuel.

Tried and tested at the highest levels of motorsport, the World's Leading Synthetic Engine Oil is simply the only choice for the enthusiastic driver. If you enjoy driving and performance really matters to you, that means you place extreme demands upon your engine. As the McLaren F1 team knows, using the right lubricant can make a significant difference, in terms of increased power output. What's more, you will enjoy the reassurance of knowing that your engine has the ultimate protection, no matter how hard you drive it.

While Mobil 1 costs a little more than other engine oils, for the simple reason that it costs rather more to produce, its unique formulation is the result of an enormous ongoing investment in research and development.
