What is oil viscosity?2018-07-19T15:30:15+00:00

Viscosity is an important criterion of any lubricating oil. It is a measure of a fluid’s thickness or resistance to flow. For example, honey is thick and water is thin, so honey has a higher viscosity than water. Oil viscosity needs to suit the right ambient temperatures. If it’s too thick when the engine is cold, it won’t move around the engine. And if it becomes too thin when the engine is hot, it won’t give the right protection to the engine parts.

Optimising an oil’s viscosity, or thickness, helps maximise energy efficiency while avoiding component wear. Viscosity modifiers increase the viscosity of your oil at high temperature but have little effect on low-temperature viscosity. These enable your oil to flow properly when cold and also to remain thick enough to protect your engine components at high temperatures.

Lower-viscosity grades of oil such as Shell Helix Ultra, make it easier for your engine to start from cold because they present less resistance to moving parts and hence take less power from your engine. This also means that you get enhanced fuel economy. To find the right oil viscosity for your engine, check your manufacturer’s guidelines and bear in mind the weather conditions you live and drive in.

What do the oil numbers mean?2018-07-19T15:30:25+00:00

Multigrade oils are those oils that have two numbers on the grade, indicating that the oil is able to maintain engine performance in high and low temperatures. A multigrade lubricant minimises viscosity differences under temperature variations.

The first number on a multigrade oil is normally followed by a W, which stands for winter. This number represents the lubricant’s viscosity under lower temperatures, giving an indication of how the oil will flow in the winter. The lower the first number, the thinner it is at low temperatures.

The second number, which appears after the W, represents the oil’s viscosity under high temperatures. The higher the number, the thicker the oil will stay at high temperatures. Using the correct viscosity for your engine increases engine performance, reduces engine wear and increases fuel efficiency.

In addition, synthetic oils usually have better low and high temperature properties than normal mineral oils. This maintains protection while allowing better fuel economy and cold starting.

What’s the difference between mineral and synthetic?2018-07-19T15:37:00+00:00

There are two main types of base oil: mineral and fully synthetic. Motor oils labelled as ‘part-’ or ‘semi-synthetic’ or ‘synthetic technology’ contain a mixture of these two types.

Mineral base oils come from crude oil that is processed in a refinery to separate out the fractions with useful lubrication properties and remove unwanted components such as waxes. Unlike some motor oil manufacturers, Shell makes its own top-class mineral base oils by selecting the best crudes and employing stringent quality control procedures throughout the entire production process.

Synthetic base oils give enhanced performance because they are manufactured using a more expensive chemical process than that used in mineral oil production. Because of this, fully synthetic oils like Shell Helix Ultra flow more easily at start-up temperatures, when most wear occurs. They are also more resistant to heat and are more easily protected by antioxidant additives (oxidation is a natural degradation process that occurs in oil over time). Plus they are less volatile than mineral oils.

What are performance additives?2018-07-19T15:42:25+00:00

Performance additives give extra protection to the base oil and enable it to protect and clean your engine, helping it to work harder for longer. They come in several kinds that must be carefully selected and blended to give top-class performance:

  • Detergents keep your engine clean and neutralise the corrosive acids that form as fuel is burned.
  • Dispersants remove soot and sludge and hold it in the oil to prevent blockages. This dirt can then be removed from your engine at the next oil change.
  • Anti-wear additives protect your engine by forming a chemical layer between the moving parts. These additives are particularly important when motoring with high loads or during engine start-up.
  • Antioxidants help to delay the natural degradation of your motor oil, hence protecting your engine more effectively for longer.
  • Friction modifiers reduce the drag between moving parts to increase fuel economy.
  • Anti-rust additives are essential elements that prevent engine corrosion.

How do I do an oil change?2018-07-19T15:51:12+00:00

Changing your car oil is easier than it sounds and could also save you money in the long term. It shouldn’t take longer than 45 minutes – just make sure that you follow your manufacturer’s specific instructions and safety directions.

Firstly, choose the ideal oil for your car from the Shell Helix range by clicking here or using our Shell Lube Match tool here. Then check you have the necessary tools.

YOU’LL NEED

  • Shell Helix Engine Oil (4 or 5 liters – check owner’s manual)
  • New oil filter – check owner’s manual
  • Safety glasses and rubber gloves
  • Plastic container and funnel
  • Car jack and jack stands
  • Drain plug socket wrench
  • Paper towels and a rag
  • Oil filter wrench

WHAT YOU HAVE TO DO

  1. PREPARE YOUR CAR

    The car should be on a level surface with the parking brake on and engine off, leaving the oil to cool for a few minutes. If you need space under the car, jack it up and use jack stands to support it. Jacks on their own are very unstable – never get under your car without using jack stands. You could also put something underneath the engine to prevent spilling oil onto the ground.

  2. UNSCREW THE OIL CAP

    Locate the oil cap (check with the manual to locate it) and unscrew it. This is very important, as a vacuum will not allow all the oil to drain out.

  3. LOCATE THE OIL DRAIN PLUG

    Get underneath the car and locate the oil drain plug. This is a lone bolt at the bottom of the oil sump.

  4. PLACE THE CONTAINER

    Place a container big enough to hold the oil beneath the oil drain plug and unscrew the plug, being careful not to let it fall into the container. Do not come in contact with the oil – it can be extremely hot.

  5. DRAIN OUT THE OLD OIL

    Allow all the oil to drain out. This can take several minutes.

  6. LOCATE THE OIL FILTER

    Locate the old oil filter with the help of your car’s owner manual. It should be identical to the one you are replacing it with.

  7. REMOVE THE OLD OIL FILTER

    Turn the filter wrench anti-clockwise to loosen the oil filter. The filter may be full of oil so take care not to spill any.

  8. PREPARE THE NEW FILTER

    Clean up the filter seat on the engine and place a light coating of oil on the gasket of the new filter.

  9. INSTALL THE NEW FILTER

    Carefully screw the new filter into place by hand, making sure it is not over-tight. Screw back in the oil drain plug and tighten it with the wrench.

  10. FILL UP WITH OIL

    Using the funnel, carefully fill the engine with Shell Helix, avoiding spillages. Measure the oil level with the dipstick after every two liters filled.

  11. CHECK THE LEVEL IS CORRECT

    When you have reached the correct level, replace the oil cap. Turn on the engine for ten minutes and then off again. Check the oil level with the dipstick once again – if the level is low, add more oil.

  12. CLEAN UP

    Clean up all oil spillages on your engine and check for any leaks from the drain plug.

  13. PROPERLY DISPOSE OF THE OLD OIL AND FILTER

    Used oil is highly toxic and must never be disposed of with domestic waste. It’s illegal to pour used oil into the sewage network. Put your used oil in a sealed container and label it. Then take it to an auto repair Centre, service station or recycling Centre. Most places will accept used oil for free.

Where can I dispose of my used oil?2018-07-19T15:53:03+00:00

What are the features and benefits of synthetic oils?2018-07-19T16:03:25+00:00

Synthetic oils have excellent viscosity control and outstanding stability over a wider temperature range than mineral based oils.

  1. Low overall viscosity means reduced friction in the fluid, resulting in improved engine efficiency and fuel economy, and better flow at lower ambient temperatures.
  2. The viscosity of synthetic oils changes less with temperature compared with a normal mineral oil. This means that the oil does not become too thick when cold or too thin when hot, which reduces engines wear at temperature extremes.
  3. The good high-temperature properties of synthetic oils mean that they are less prone to thinning at high temperatures. This gives better protection at high engine speeds (rpm) and when heavily loaded.
