The range of viscosity grades available allows drivers to select the ideal oil viscosity recommended for their vehicle's engine. Lower viscosity oils like 0W-20 provide better fuel economy and flow at colder temperatures, while higher viscosity oils like 20W-50 give more protection at hotter engine operating temperatures.

Synthetic vs Conventional

Synthetic and conventional motor oils have some key differences that drivers should understand when selecting the right oil for their vehicle.

Synthetic Oil

• Made from chemically modified crude oil components to create customized molecules that improve certain properties like cold flow and oxidation resistance. This allows for better performance.

• More stable at extreme temperatures so better protection in very cold and very hot weather.

• Lower coefficient of friction so can improve fuel economy.

• Better viscosity at low temperatures so easier cold starts.

• More resistant to oxidation so can last longer between oil changes, often double or more compared to conventional.

Conventional Oil

• Made from crude oil with less chemical processing and manipulation. The molecules are more inconsistent.

• Does not perform as well at temperature extremes or hold up to oxidation as long.

• Typically requires more frequent oil changes than synthetic.

• Less expensive option than synthetic. Some vehicles do not require synthetic.

The main tradeoffs are that synthetic offers improved performance and durability but at a higher cost, while conventional is more affordable but needs replacement sooner. Drivers should consult their owner's manual for the recommended oil type. Many modern engines can benefit from upgraded protection of synthetic.

Castrol Oil Change Frequency

When it comes to changing your Castrol motor oil, it's important to follow the manufacturer's recommendations for oil change frequency. Most automakers recommend changing your oil every 5,000-7,500 miles or every 6-12 months, whichever comes first. However, some factors may require more frequent oil changes:

• Driving Conditions - If you frequently drive in stop-and-go traffic, haul heavy loads, drive on dirt or dusty roads or drive for extended periods at high speeds, you may need to change your oil more often. These harsh conditions cause oil to break down more quickly.

• Vehicle Age - Older engines may burn oil more rapidly and require more frequent changes. As an engine accumulates miles, it's a good idea to check the oil level more frequently and top off if needed. Changing the oil more often can help remove sludge that builds up over time.

• Climate - Extreme hot or cold temperatures can impact oil life. If you live in an area with temperature extremes, changing the oil ahead of manufacturer intervals can be beneficial.

The bottom line is that while Castrol motor oils are high-quality, following the automaker's recommendations based on your driving conditions and habits will help optimize performance and engine life. Don't hesitate to change oil more frequently if needed.

Castrol Oil Filters

When it comes to oil filters, you have two main options - OEM filters from the vehicle manufacturer or aftermarket filters. Castrol recommends using OEM oil filters for optimal performance.

OEM oil filters are designed specifically for your make and model. They go through extensive testing and quality control to meet the vehicle manufacturer's specifications. Aftermarket filters may be cheaper, but they are essentially generic and may not provide the same level of filtration.

Most modern vehicles use a spin-on oil filter design. This is a canister style filter that spins onto the engine block. Spin-on filters are convenient since the filter housing is part of the filter itself. Older cartridge-style filters use a separate housing that the filter cartridge fits into.

Sticking with OEM oil filters is the best way to maintain your warranty protection. Aftermarket filters may cause issues that the manufacturer can blame on "non-approved" parts. For optimal engine protection, always replace your oil filter at the recommended interval using the specific OEM filter.
