Q. Why is an engine oil’s ability to cleanse important?

A. 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. Pentex engine oils are designed to clean and protect engines for improved performance.

Q. Why is the choice of engine oil so important?

A. Oil is the lifeblood 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 Pentex oil 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.

Q. How does oil protect my engine?

A. In many ways:

• By cleaning the engine – Pentex 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.
• By reducing friction and minimising wear – Pentex 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.
• By removing heat – Pentex 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.
• By preventing corrosion and rust – Pentex oils help to protect your hard-working engine components from corrosion beyond the normal oil-change interval. Benchmarking studies show that Pentex oils provide best-in-class protection and help to extend your engine’s life and avoid some expensive repairs.

Q. Why is engine oil’s made from?

A. 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.

Q. Is it important to change oil and how often should I do this?

A. 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.

Q. How should I dispose of used oil?

A. 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.

Q. Why is Pentex any better than other leading brands?

A. We have put Penex's years of know-how in oil development into every aspect of the Pentex formula – from the base-oil technology through to the additives’ selection and blending.

Q. Will I really notice the difference if I don’t make frequent oil changes?

A. 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.

Q. Why not just keep topping up the engine oil?

A. 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. Pentex oil has a powerful ability to clean up your engine components and goes on keeping engines clean through to the next oil change.
