Castrol 03128C, 5W-30 For Nishan Titan


Castor is one of the ancient brands in the automotive oil industry. It also brings versatile oils considering the engine’s and your needs. Castrol Edge and GTX are two of them. 

Castrol Edge Vs GTX

Castrol Edge’s specialty is to dramatically reduce premature engine wear with superior high temp protection and anti-wear performance. Offering higher viscosity stability is another benefit to reducing oil consumption. 

On the other hand, GTX efficiently offers you 6x better wear and 1.4x better sludge protection. Due to the smooth lubrication system of the engine, it’ll last longer than usual. 

Apart from these basic differences, they both also differ in many cases. And in this post, we’ll let you know all one by one. So if you want to choose the right food for your engine to get peace-minded driving on the road, don’t leave us here.

A Quick Overview Of Castrol Edge Oil

Castrol formulated its edge synthetic oil keeping in mind the highest protection of your engine even in extremely harsh weather. 

The Fluid Titanium Technology ensures the proper bending of its anti-wear and anti-frictional agents to reduce rubbing between the components. So tiny particles like sludge, won’t create and block the piston valves.

That means the oil remains clean for a long time with adequate viscosity stability to improve by 30% better film strength. So it won’t evaporate due to higher temperatures, and it offers you 6 times better wear protection than many other industrial oils. 

Unique Benefits

  • Unlock your engine’s maximum performance by reducing oil breakdown 
  • Excellent heat resistance makes it worth using in the hottest cities
  • Prevent metallic engagement to enhance engine lifespan
  • Good fit for most vehicles irrespective of age and types


  • Some people won’t prefer it for everyday use due to the higher price

A Quick Overview Of Castrol GTX Oil

Castrol GTX oil is formulated to kick out your poor engine performance in cold weather resulting in sludge and deposit buildup. 

Sludge, the main culprit that contaminates your engine oil, lowers its quality and viscosity. The Unique Trishield Technology of GTX oil and the anti-wear additives fight against sludge building. 

The oil flows into the engine’s metal parts effortlessly to offer better engine optimization. So on the road, you’ll get quiet, smooth, and high-mileage performance. 

Unique Benefits

  • Keep the engine clean for a longer time without needing repair
  • Offer superior protection and prevention from wear and deposits 
  • High mileage efficiency, but less expensive 
  • Perfect choice for cold weather to avoid cold starting hassle


  • Lower oil changing interval 

A Detailed Comparison Between Castrol Edge vs GTX

Though both of these oils are manufactured by the same company, you won’t find them the same. However, let’s see some of the distinct differences. 

1. Formulation & Certifications 

Following the right technology, having the right chemicals with the right proportion, and proper blending is the most important way to keep the oil stronger to serve your purpose. Once the oil maintains all those criteria, the authority institutions certify them as quality engine oil. 

  • Castrol Edge 

This oil contains multiple chemicals like antioxidants, anti-wear detergents, and agents. These are blended following Fluid  Titanium technology. So it meets and exceeds the IVA test, API SN PLUS approval, and other industry standards as quality oil. 

  • Castrol GTX 

Regarding oil formulation and quality, the GTX also meets the industry benchmarks, such as the ILSAC GF-6 standard, Ford Wss-M2C930-A, Ms 6395, and Gm 6094M. 

Following the Unique Trishield Technology, all the special additives are blended into the oil to make it stronger to fight against heat in extreme driving conditions. No compromise about quality. 

2. Viscosity Grade 

The next difference between them is their available viscosity grade. When one is formulated for prioritizing lower temp weather, the other is for high temp. And knowing their viscosity, you can identify them. 

  • Castrol Edge

You’ll find the higher 7 types of viscose oil from the Castrol edge, which are excellent to use in extreme cold and heat. So, no matter if your local weather conditions are too cold in winter or too hot in summer. 

Castrol edge engine oil will align with your needs, irrespective of state, weather, and heat. You can choose 0W-16, 0W-20, or 5W-20 for bone-chilling cold weather and 10W-30 or 5W-50 for sweat-breaking hot weather. 

  • Castrol GTX 

10W-30, 10W-40, and 20W-50 are the GTX available viscosity grade oils suitable for colder climates. But that doesn’t mean they are ineffective in high-heat weather. 

The 5W-50 viscosity oil’s right digit is 50, so it can be incorporated with normal hot weather instead of extreme. So, if you live in a mostly cold-based region with typical heat in summer. You will be free from the hassle of seasonal oil changing hassle. 

3. Protection & Prevention 

Protection and prevention (PP) are other differential factors between these two oils. You need protective engine oil to fight against heat and between component engagement. The preventive oil remains clean, has proper viscosity, and faster flowing through the critical parts.   

  • Castrol Edge 

Your engine will perform better under harsh weather with the Castrol edge oil due to its different anti-wear agents. The parts will smoothly rotate during operation without each other friction. 

The smoother rotation means lower deposit buildup, lower oil breakdown, and higher engine life. 

  • Castrol GTX 

The colder the weather, the higher the humidity level, the higher the sludge formation, and the higher the cold-start hassle. 

Here the GTX wins the race with the edge because it’ll provide at least 50% better sludge prevention. And lower sludge will promote higher engine protection from unexpected rust and corrosion. 

4. Mileage Efficiency & Fuel Economy

ME and FE both are co-related in choosing the engine oil. The higher the mileage efficiency, the lower cost, and vice versa. 

The logic is very simple behind it. The more miles you can drive with one gallon of oil, the less you have to buy.  

  • Castrol Edge 

Since the focus point of the oil was high heat resistance, it won’t offer you higher mileage efficiency like the GTX. The company offers you around 20,000 miles of efficiency from this oil. 

But, many users claimed they drove their vehicles more than these miles based on their driving skills, roads, and weather conditions. 

Considering the fuel price and mileage efficiency, it’s not better than the GTX.  

  • Castrol GTX

Higher 75000 miles running thrives you on the road, and if it adds a lower price, then boom. 

The science behind the higher mileage efficiency is the cold weather. Because when natural high heat + internal engine heat puts too much pressure on the engine and oil, the engine can’t perform at its peak. 

But, in cold weather, the engine won’t struggle with its internal high heat for natural cold weather. 

However, whatever the reason is, Castrol GTX offers the best mileage performance and fuel efficiency. 

5. Compatible Engine & Vehicles 

Different engine types with multiple types and branded vehicles are available in the market. And you may have anyone according to your needs. The oil’s engine and vehicle compatibility should match your one. 

  • Castrol Edge 

Castrol Edge cares about your gasoline, petrol, or diesel-powered engine and is compatible with them. 

Whatever vehicle you have, from  2-stroke motorcycles to 4-stroke cars, you can confidently pour this oil into its stomach. 

In terms of brands, BMW, Mercedes, Ford, Audi, Volkswagen, and Land Rover will run excellently with this oil. 

  • Castrol GTX 

Turbocharged Diesel, Gasoline, or Petrol, all engines will cooperate with Castrol GTX oil. You can use this oil for your passenger cars, light-duty trucks, vans, ATVs, and SUVs

6. Oil Changing Interval

Nothing is more stressful and frustrating than needing to change the oil during the trip. The higher oil changing interval also puts a smile on your rosy lip on the long journey. 

  • Castrol Edge 

It offers higher oil change intervals of up to 10000 miles between the oil change. And this time, it’ll maintain excellent strength and unsurpassed protection. Moreover, you can go 15000 miles with better driving skills on a flat road. 

  • Castrol GTX 

Though it’s not full synthetic oil like the edge, you can drive your vehicle 5000 to 6000 miles before the next oil change. But, the unfortunate matter is that you still have to change the oil if you don’t drive 5000 miles within 3 months.
