If you’re looking for the very best motor oil, then Castrol should be top of your list. Castrol, along with Mobil is known as one of the finest producers of oils and lubricants in the world. You’ll find Castrol oil in everything from cars, vans and industrial machinery through to everyday items that keep the world running smoothly.

With over a century of experience in creating oils for different industries, Castrol’s oils can be trusted to keep your engine ticking over, whatever you drive, from Honda through to BMW. Castrol has been working hard to make sure their oils are as sustainable as possible. Using their oils can help your car run to its best abilities, which in turn will keep your emissions low.

Castrol car oil falls into two product ranges; Castrol Edge and Castrol Magnatec. At Cox Motor Parts we stock both, and we can help you find the perfect Castrol motor oil for your Honda.

If you are unsure which engine oil you need for your vehicle, we have an extensive oil and fluid information guide which shows which oil is suitable for each car.

What is the best Castrol Oil?

Castrol Edge Engine Oil

Say goodbye to your fears about friction hotspots in your engine. Castrol Edge has been created with Fluid TITANIUM to allow it to transform its structure as it glides around your engine. This technology allows it to become stiffer at any points where the pressure drastically increases, making sure there’s a layer of oil to keep any pieces of metal apart.

The varieties we stock include Castrol Edge 5W40 oil, in sizes from 1 litre to 4 and 5 litre bottles, as well as Castrol Edge 0w30 and Castrol Edge Professional. These are all designed to limit the friction in your car’s engine through Castrol’s TITANIUM technology.

  • At its strongest under high pressure
  • Minimises friction to maximise power
  • Meets highest standards possible after stringent testing
  • Protects engine during entire drain interval
  • Reduces wear & tear
  • Improves fuel economy
  • Offers the best performance of any Castrol oil or lubricant

Castrol Magnatec Engine Oil

If you live in a city and are concerned about the wear and tear caused by warm-up wear and stop-start wear then Castrol Magnatec Oil could be exactly what you’re after. Designed for urban environments where you’re going to be stopping and starting your car far more frequently, Castrol Magnatec Oil has been developed and patented to allow molecules to cling to critical parts of your engine to protect them.

You’ll find Castrol’s DUALOCK technology in the Castrol Magnatec 0W30 car oil, that’s fully synthetic and designed to prevent stop-start wear. We stock Castrol Magnatec 0W30 for people to use in their Honda engines, to get the best performance and protect them from wear and tear.

Why buy Castrol Engine Oil?

Castrol are one of the leading manufacturers of synthetic oils and they’re perfect for modern engines. Here are few of the reasons why we’re so keen on Castrol Engine Oil:

  • They use liquid engineering for optimal viscosity to keep your engines and parts safe
  • Castrol create synthetic oils focused on engine performance
  • Optimised for stress points caused by all driving conditions
  • Castrol products are designed for high temperatures, low temperatures and stop-start city driving
  • Lubricants created to resist sludge while protecting your engine
  • Known for their quality oils and lubricants that deliver high performance

While choosing the right lubricant for your engine may only feel like a small choice, Castrol engine oil is one of the safest investments you can make. They use the latest technology to engineer Castrol oils to enhance performance while offering maximum protection.

Is Castrol oil better than Mobil?

This isn’t a question that’s easily answered. Both Castrol and Mobil have their strengths, and their weaknesses. Their oils are designed to cater for slightly different needs and each offers lubricants that work better under different conditions.

Choosing an oil that’s best for your driving needs and following the right change intervals is key for getting the most out of your car and the oils that you use, regardless of brand. In general, Castrol oils offer excellent engine performance, smooth running and help cars last for a long time, even if it’s a slightly older motor. Mobil 1’s oils on the other hand offer lubricants that will keep new engines in tip top shape and help you drive them at peak performance. Either is a great choice for your automobile.
