What are the right lubricants your car?
UNLOCK THE VERY EDGE OF PERFORMANCE
Worldwide emissions regulations are tightening, renewing the challenge to maintain the engine power and performance expected by drivers.
Castrol EDGE is tested at the highest standards to meet the challenge of maintaining the high-performance levels expected by drivers, whilst engine technology adapts to meet the demanding legislative limits.
Recommended for world-leading car manufacturers, Castrol now delivers More Power. Same Fuel¹. The Castrol EDGE range:
Delivers more horsepower and greater acceleration to get you more metres ahead²
Demonstrates improved performance as a result of better fuel economy
¹ Greater power delivery for normalised fuel consumption relative to 5W-40 baseline, demonstrated by engine testing for more than 80% of the Castrol EDGE portfolio in volume in 2021.
² Demonstrated in Castrol engine testing; distance ahead relative to 5W-40 baseline over road load accelerations.
NON-STOP PROTECTION FROM EVERY START
Castrol MAGNATEC engine oil, featuring DUALOCK technology, is specifically engineered for today’s urban driving environment and designed to protect engines against the wear caused by re-starting in busy traffic.
The patented molecule in DUALOCK Technology helps provide 50% better protection from warm-up wear* and re-start wear.

Castrol GTX helps extend engine life by tackling the main causes of sludge.
It’s advanced 3X-Protect formula surrounds and suspends dirt particles to keep engines cleaner for longer.
Giving you and your vehicle more miles together.
When it’s time for an oil change, knowing what motor oil to use is essential. The answer to that question gets more complex every day. The latest engines are getting smaller and more powerful all the time, and manufacturers are specifying complex full synthetic oils to cope with higher engine pressures and meet fuel efficiency targets.
If you’re driving a muscle car or a European import, the manufacturer may well specify a full synthetic motor oil. Alternatively if you’re driving an older domestic vehicle, the manufacturer may recommend a conventional oil. However, even though that’s the most economical option, a full synthetic will almost certainly look after your engine better. Knowing what engine oil to use at every oil change is essential.
Your owner’s manual will tell you which industry specification, type and grade of oil the manufacturer specifies.
Viscosity is a measurement of the thickness and ‘ease of flow’ in any liquid. For example, water is a thin liquid that flows freely, so we say that it has a low viscosity. Honey, on the other hand, is relatively thick and flows more slowly. So we describe honey as having a high viscosity. It’s also worth noting that honey flows more easily – and is therefore less viscous – when it is slightly warm. Motor oil behaves in pretty much the same way, which is why mechanics will usually run an engine for a minute or two before draining used motor oil away to replace it.
