Comparison between Castrol Magnatec, Castrol Edge, and Castrol GTX

 

Differences You Can’t Ignore:-

  • Features: Castrol Edge is the manufacturer’s most premium engine oil specially designed for performance vehicles although it could be used for general vehicles as well. Castrol Edge is specifically manufactured for modern-day vehicles where the engine is getting smaller and more efficient, which put the engine oil to test with increasing pressure. Castrol Magnatec is made primarily for heavy traffic conditions and short trips.Castrol says that up to 75% of engine wear happens during cold start, Magnatec is very useful in these conditions as it is equipped with ‘DUALOCK technology’ which ensures that the oil particles cling onto the engine components, so that engine wear and tear is reduced. Castrol GTX is standard engine oil that provides great value for its price. It was introduced primarily to extend the engine life and is very effective in cleaning sludge and preventing new sludge from forming.
  • Suitable Models: Although all the 3 products are suitable for high-performance or regular powerplants, there are certain engine oils within the GTX, Magnatec, and Edge range that are specifically designed for high-performance and regular engines respectively. Castrol Edge is designed specifically for modern-day engines. Then, there are a few products that are specifically engineered for high-mileage vehicles.
  • Longevity: After testing all the 3 engine oils through a variety of tests, it can be concluded that Castrol GTX retains its oil properties the longest, after which comes Castrol Magnatec, which also provides good shelf life due to its clinging property. Castrol Edge, even though, being the most premium engine oil in Castrol’s range of engine oils, has the least shelf life and loses its oil properties earlier than the other two.
  • Cost: Being the most premium offering, Castrol Edge is the most expensive out of the 3, Castrol Magnatec is the second most expensive, and Castrol GTX is the cheapest of the lot.

 

 

Similarities:

  • Suitable Engines: All of the above-mentioned engine oils are compatible with both gasoline and diesel powertrains.
  • Oil type: All 3 engine oils are available in fully-synthetic forms. While Magnetic and Edge are available only in synthetic forms, GTX is a premium conventional mineral grade oil.
  • Reliability: All the engine oils are thoroughly proven products, and are extensively tested for various conditions. Thus, there are no questions asked over the reliability of these Castrol products.

2) Castrol GTX MAGNATEC 5W-30 Full Synthetic Motor Oil

Castrol GTX MAGNATEC 5W-30 Full Synthetic Motor Oil

When the engine of the car is not in use, the engine oil lubricating the engine is gradually collected in the oil sump. Now, when the engine is started, it takes time for the oil to reach various critical engine components and therefore, the engine has to work for some time without the lubrication of the engine oil. This is the major reason for the wear and tear of the engine.

Castrol Magnatec is a fully-synthetic oil that has advanced ‘DUALOCK technology’ which helps the oil particles to stick to the engine components, therefore when the engine is started, it is already lubricated to a certain extent, thereby significantly decreasing the wear and tear caused to the engine.

Salient features:-

  • It has been optimized to meet stringent industry standards and has been ‘Dexos 1 gen 2’ approved which means that it is specifically formulated to use in General Motors (GM)
  • Reduces Engine wear, keeping the critical engine parts up to 4X smoother.
  • Provides excellent protection in the warm-up of the engine, which is during the first 20 minutes of the engine start, because during this time, the engine is prone to most of the wear and tear.
  • Its viscosity grade is 5W-30, which means it has a viscosity rating of 5 at winter temperatures, and 30 at operating temperatures (220 degrees Fahrenheit).

Downsides:-

  • Engine performance is not as good as Castrol Edge engine oils.
  • It is costlier than conventional and semi-synthetic engine oils such as Castrol GTX.


Pro-Tip
– Castrol Magnatec is a must-have engine oil for heavy traffic conditions.

Castrol Edge high mileage is low-cost synthetic oil that offers superb value for your high mileage car. It reduces leakage and oil burn-off. There have been some reports of engine noise.

Castrol GTX’s high mileage comes specifically for vehicles clocking 75,000 miles in the odometer. The oil is made by professionals to help prevent sludge build.

Castrol Edge Vs Magnatec 5W30

Castrol Edge is thinner engine oil in comparison to Castrol Magnatec. As temperature rises Castrol Magnatec is able to maintain a suitable thickness, the Castrol edge gets thinner. Castrol Magnatec has a longer shelf life than Castrol Edge.

Castrol Edge with its Fluid Titanium technology is an expert in handling high pressure and decreasing friction.

In Castrol Magnatec Intelligent molecules are present that cling to the surface which creates the best anti-wear system.

Castrol Magnatec Vs Edge Titanium

Castrol Magnatec has laboratory-made intelligent molecules that cling to critical engine parts like a magnet, providing an extra layer of protection from the start and throughout warmup that won’t drain the sump.

Castrol Edge with its advanced ‘Fluid TITANIUM’ technology provides superior engine wear protection. It offers a high level of high-temperature protection, anti-wear performance, and viscosity stability.

Castrol Magnatec Professional VS Castrol Edge

Castrol Magnatec professional is specifically made in collaboration with Ford motors to meet modern emission standards and fuel economy. It tends to focus mostly on warm-up wear, while Edge emphasizes reducing friction under high-pressure settings. In a general sense, Castrol Edge has a lead over Magnatec Professional since it meets and even exceeds the highest standards of performance, though the protection offered by Castrol Magnatec Professional in heavy traffic conditions and frequent start-stops is unmatchable.

Castrol Magnatec VS GTX ultraclean

Castrol GTX ultraclean is a semi-synthetic engine oil with double action formula that has proven to clean away the sludge which can block engine oilways. It also prevents new sludge formation, thanks to its synthetic technology. In fact, it provides much better sludge protection than is demanded by the latest industry standards.

The fully-synthetic Castrol Magnatec, on the other hand, focuses more on protecting the engine in heavy traffic conditions and short trips.
