Stocking an extensive array of brands and viscosities means whether it's a 10w-30 semi synthetic engine oil, a 5w-30 full synthetic engine oil or a basic mineral oil, we cater for your vehicle and driving style. Our partnerships with companies such as Penrite, Castrol, Nulon, and other leading brands ensure you have the cutting edge technology and highest grade formulations when it comes to the right engine oil for vehicle.

Choosing the Right Engine OilWhen choosing a motor oil for your car, the most important thing is the viscosity and the easiest way to pick the best engine oils for your car is to consult the owner's manual. Different engines require different viscosity engine oil to protect and operate correctly, depending on the manufacturer specifications. In simple terms, viscosity just means thickness. A low viscosity or light weight engine oil will appear smooth and flowing like water, however a higher viscosity or heavier oil will appear thicker, similar to honey or maple syrup.

What Is the Difference Between a Mineral Engine Oil and Synthetic Engine Oil?

Designed to suit a range of engine types, applications, driving styles and budgets, one of the main variations between oils are whether they are a fully synthetic, semi-synthetic, or mineral based engine oil.

  • Mineral oils use more base oils and suit every-day use and are usually the right oil for older vehicles. However, for higher levels of protection and cleaning under intense driving conditions, semi-synthetic and full synthetic engine oils can be a better option.
  • Semi-synthetic engine oils are a great middle ground, featuring some of the best bits of the full synthetic option whilst offering a well-performing lubrication solution that is friendly to your wallet. These engine oils work by offering better resistance to friction on metal surfaces in both low and high operating temperatures when compared to a mineral engine oil.
  • Full synthetic engine oil will undergo an extensive lab treatment to provide a mixture of chemical additives and oil that make them perform significantly better than their mineral base oil counterparts. Apart from better extreme temperature performance, synthetic engine oils are formulated to provide low sludge and less corrosion formation as well as containing better detergents when you compare with mineral and synthetic oils. They also provide greater fuel economy based on their low viscosity. Keep in mind that the refining process is expensive and lengthy typically making synthetic engine oils the most expensive on the market.

Popular Questions Asked

What Oil Does My Car Take?

There are a few different ways you can figure out what oil your car needs. Repco's Rego Search function will tell you which oil your car needs based on the make and model, your owner's manual will have the information, and if you have a spare top-up bottle lying around from a recent oil change that will also let you know. You can also just do a quick Google search for your make and model and that will likely tell you.

How To Check Your Engine Oil

  1. Start by making sure your car is in park and on ground level (an angled car will tilt the oil level as well) with the parking brake on.
  2. Lift the hood and locate the dipstick, which you can usually find by its bright yellow or orange colour and its location near the oil cap, which will often have a picture of an oil can on it.
  3. Pull the dipstick out of its housing and take a look at the two lines at the bottom. The lower line indicates the minimum oil level for your car and the upper line shows you the maximum, you'll want your oil level to be somewhere between these two points.
  4. If there is oil residue below the bottom line or if there is no oil at all on the dipstick, then you'll need to top your oil up to just below the maximum line immediately.

How To Dispose of Motor Oil

Don't dump your oil down your sink, into your rubbish bin, or in your garden.

What you'll want to do instead is find your nearest oil recycling facility. Council facilities like landfill sites, transfer stations, and waste management centres will often take your used oil and there are local council programs that will take household chemicals and engine oil.

Local petrol stations will sometimes take motor oil and other facilities will even take things like oily rags, containers, and oil filters off your hands.

What Does 5w30 Oil Mean?

The number on your engine oil container indicates the viscosity of the oil in certain temperatures. Viscosity means the thickness of the oil, with a lower number meaning a thinner oil and a higher number being thicker.

The number that ends with a W indicates that it relates to the viscosity of the oil in winter or, more specifically, in cold temperatures, while the other number is for hot temperatures.

Can I Use 10w30 Oil Instead of 5w30?

In many cases, using a 10W30 oil instead of a 5W30 will be fine, as the second number is the same, meaning that both oils will flow at the same viscosity when the engine reaches operating temperature. You might have more difficulty with cold starts using a 10W30 though, as the thicker viscosity will mean the oil won't flow as readily and may not lubricate as quickly.

The best option is to always use the engine oil recommended by your owner's manual.

How Often Do You Need To Change Your Oil?

An oil change will need to be performed as part of the servicing schedule set out by the vehicle's manufacturer and can be anywhere from 3-6 months. You might need to change your oil more often if you tow heavy loads or work in harsh conditions consistently due to the extra strain on the engine.

Driving your car infrequently and for short distances can cause condensation to build up, as the engine isn't getting hot enough to boil it away, which can cause your oil to break down faster. Frequent oil changes can help to remedy this type of driving.
