Since 5W-30 is the grade specified for the majority of modern petrol and diesel cars, and a fully synthetic formulation is what most manufacturers now require, the 5-litre pack has become the standard service purchase.

Shop 5-litre 5W-30 by specification

The approval your vehicle requires matters as much as the viscosity. Our 5L range includes low-SAPS C3 products for vehicles with diesel particulate filters, alongside oils meeting other common manufacturer specifications such as VW 504.00/507.00, MB 229.51 and dexos2. Check your handbook or use our oil finder to confirm which applies.

Why buy 5 litres?

Most family cars take between 4 and 5.5 litres at a service, so a 5-litre container covers the change with little waste, and any remainder is useful for topping up between services. The cost per litre is typically lower than buying multiple 1-litre bottles.

Need a different size?

If you are topping up rather than servicing, our 1-litre 5W-30 fully synthetic engine oil range is the better buy. You can also browse all 5W-30 fully synthetic oil or the wider 5-litre engine oil selection across grades.

How much oil does my car need?

Capacity varies by engine rather than by model, typically between 3.5 and 6 litres for a passenger car. Your handbook will confirm the exact figure, and it is worth checking before ordering so you buy the right quantity first time.

What's the difference between 5W-30 and 5W-40 oil?

Both grades protect equally on cold starts, since the '5W' rating is the same. The difference is the operating temperature: 5W-30 runs thinner, suiting modern, efficiency-focused engines, while 5W-40 stays thicker, offering more film strength for older engines or sustained high-load driving like towing.

How often should I change my engine oil?

Most manufacturers recommend every 10,000–12,000 miles or once a year, whichever comes first, though this varies by vehicle and driving style — check your service schedule for the exact interval.

How long does 5W-30 oil last once opened?

An opened bottle is generally fine for up to two years if the cap is sealed tightly and it's stored somewhere cool and dark, away from direct sunlight.
