That is to say that this oil provides exceptional temperature protection in any severe weather conditions and prevents oil from thermal breakdown. After Mobil 1 oil, Pennzoil Platinum full synthetic oil is another wonderful oil that delivers all-round performance to the engine. To know which viscosity is perfectly suited for the model of your vehicle, first look at what is the manufacturer’s recommendation. This oil is recommended for all types of modern gasoline powered vehicles ranging from high performance turbocharged passenger cars to SUVs to light vans. Older cars are more prone to oil leaks problems due to the wear causing increase in oil consumption. This oil’s anti wear additive shield against wear and help to minimize oil consumption. Overall, It provides excellent performance and extends engine life.

The advanced additive protects the engine parts from wear. The added detergents remove oil sludge and deposit and keep the engine clean. As oil changing is considered to be a mundane task, needless to change oil frequently brings you relief. For instance, Rotary engines especially need conventional oil. Mazda does not recommend synthetic oil for their RX7 and RX8 models as they are concerned that some synthetic oil can proliferate carbon deposits inside the engine. This oil maintains excellent film strength and doesn’t break down in heat. It has even extended oil change interval upto 10,000 miles which can save you from changing oil at short intervals.This oil is great for high mileage engines or older engines. Castrol assured that this oil is specifically made for the engine over 75,000 which is the minimal range for an engine to be considered high mileage. Although there is no official expiry date expressed on oil containers or manuals, the motor oil can last for a longer period of time. Its 10w-30 oil is a useful touchstone for modern turbocharged engines. According to Pennzoil, this oil keeps the piston upto 40% cleaner than toughest industry standard and which makes the oil standout than any leading synthetic oil. Its uniform synthetic oil molecules and advanced additive technology help to reduce wear and also prevent deposits and sludge buildups. Its quality can completely run out and using this oil can cause more harm than good to the engine. Conclusion

Castrol GTX 10W-30 Motor Oil exclusively designed for protecting against sludge buildups. As older cars contain more sludge and carbon deposits, this oil’s double-action formula removes old sludge and keeps the engine healthy. If you drive in a weather condition where temperature ranging from 0 to 60 or 70°F, 10w-30 viscosity can be a decent option in that environment that provides all round protection from extreme ambient temperature. This oil is the undisputed champion of all the 10w-30 viscosity oils. Considering the quality and service it provides, It is a benchmark of all its competitors. That’s how fuel economy is improved in a less viscosity oil. Although both 10W-30 and 10w-40 are practically pretty much the same oil, theoretically 10w-40 should be more fuel-efficient at engine’s operating temperature as it has less viscosity grade than the 10w-40.
