Which Oil Does My Car Need?

It’s vital to check your vehicle’s oil. Here’s why.

Did you know that approximately 1 in 4 cars are low on oil?

We’re all guilty of not checking our oil as often as we should – or leaving it until the warning lights come on, when the oil level is already too low. Correct oil levels lubricate the moving parts of an engine and help to maintain the health of your vehicle.

Oil Change

The correct and fresh oil helps to increase engine life, aid fuel efficiency and helps you get maximum power and performance from you vehicle.  Oil is the blood of an engine and reduces metal on metal friction to minimise the risk of damage which could be caused by the heat produced by the internal components.

There are oils available for the modern vehicle and you can be assured that ATS Euromaster has access to the latest oil products. We offer superior quality Shell Oil and Lubricants at competitive prices.

Our highly qualified technicians will be on hand to give you advice and help you identify the most suitable oil for your vehicle in line with your vehicle manufactures  recommendations.

Why Should I Change My Oil? 

No matter how well maintained engines are, the system will generate dirt and deposits that contaminates the oil. The oil filter will initially remove any dirt from the oil, however the filter will eventually clog up making the oil cleansing process ineffective.

The dirty oil circulated around the engine will not be as effective in lubricating the system as originally planned.  The dirt can impact the engine’s responsiveness and performance over time. 

Once the oil becomes contaminated, it will stop lubricating the engine to best effect, potentially leading to engine damage. 

ATS Euromaster recommends that engine oil levels are checked once every month.

How to Check Your Oil Level

A quick guide to checking your oil

  • Step 1: Open the bonnet Park your car on a horizontal level – not on a hill. Ensure your engine is cold or not been running for at least 15 minutes. Then, release your bonnet catch and secure the bonnet open.
  • Step 2: Find the dipstick Now take a look round for the top of the dipstick. It’s normally circular and always located next to the engine. Any difficulties please refer to your vehicle’s handbook.
  • Step 3: Check the oil level Take out the dipstick and clean off any oil. Pay particular attention to the area where the minimum and maximum indicators are marked at the bottom of the dipstick. Once clean, fully reinsert the dipstick into the engine. Then, carefully remove and examine where the oil level appears in relation to maximum and minimum markings (or upper or lower).
  • Step 4: How to top up your oil Remove the oil cap and pour the oil into the reservoir little at a time. Take care not to spill any oil on the engine. Every so often check the oil level with the dipstick and continue to add oil until the higher level is reached. Replace oil cap making sure it’s on tight.

Tip: Take care not to overfill the oil. 

It pays to check your oil, the average bill to repair an engine damaged by lack of oil is a whopping £1,400 as reported by AutoCar.

According to AutoCar, half of all motorists fail to check their car’s oil at the recommended once-monthly intervals and 28% never check the level at all.

Furthermore, Britannia Rescue reported that 68% don’t know how to check their oil. 

Mineral and Synthetic Shell Oil

There are two types of base oil, mineral and fully synthetic.

Mineral base oils come from crude oil which is processed to remove out fractions with useful lubricant properties and remove unwanted components such as waxes. Shell provide their own top-class mineral base oils by selecting the best crudes and extracting the oil under advanced quality control procedures.

Synthetic base oils offer an enhanced performance in hot and cold weather conditions as they are manufactured using a more expensive chemical process than that used in mineral oil production. Synthetic oils such as Shell Helix are of a higher purity and quality when compared to mineral base oils as they contain less unwanted components.

What do Oil Numbers Mean? 

Multigrade oils have two numbers on the grade, the oil is able to maintain engine performance in high and low temperatures.  A multigrade oil reduces viscosity differences under temperatures.

The first number on a multigrade oil is normally followed by ‘W’, which stands for winter. This number represented the viscosity under lower temperatures. The lower the first number, the thinner the oil.

The second number which appears after the ‘W’ is the oil viscosity under higher temperatures. The higher the second number, the thicker the lower will remain in hot temperatures.

The correct oil viscosity, or oil thickness can benefit you buy improving energy efficiency, enhancing fuel economy and protecting your engine parts.

Synthetic oils usually have better low and high temperature properties than mineral oils. 

What is Oil Viscosity?

Viscosity is a measure of an oil’s thickness and ability to flow at certain temperatures.  Generally, the thicker the oil, the higher the viscosity, and the thinner the oil, the lower the viscosity.

The SAE viscosity grade is written as SAE XW-Y, where X is related to low-temperature viscosity and Y is related to high-temperature viscosity.

The low-temperature viscosity indicates how well the oil will flow to lubricate critical engine parts at low temperatures.  The lower the number, the more easily the engine will start in cold weather.

The high-temperature viscosity provides thickness for good lubrication at operating temperatures.

The SAE viscosity classification says NOTHING about oil quality.

All oils thin when heated, but multigrade oils thin less than monograde oils (also called single-grade or straight-grade oils).  Less thinning provides a more consistent oil pressure.

The viscosity index indicates how much the oil will thin when it is subjected to heat.  The higher the index, the less an oil will thin when it is heated.

What is Shell's new PurePlus Technology?

Shell Helix Ultra passenger car motor oils are formulated using the unique Shell PurePlus Technology, a leading-edge gas-to-liquids technology process that converts natural gas into base oil.

Compared with traditional group II and group III base oils (generally refined from petroleum crude oil), Shell PurePlus Technology provides enhanced (viscosity, friction and volatility) performance, and offers the opportunity to develop superior lubricants for the most advanced engines, making Shell Helix Ultra their newest, most advanced motor oil ever.
