Car oil types include conventional, synthetic, and synthetic blend oils. Conventional oils, derived directly from crude oil, are suitable for vehicles with simple engine designs. Synthetic oils, engineered with chemical compounds, offer superior performance in extreme temperatures and better engine protection, making them ideal for modern engines and high-performance cars. Synthetic blend oils combine the best of both, offering better performance than conventional oils at a lower cost than full synthetics. Each type has its specific viscosity grades and service ratings to match different engine requirements and driving conditions. Choosing the right oil involves considering your vehicle’s age, manufacturer recommendations, and driving habits.
In hot weather, engines require oil that can maintain viscosity and lubricate effectively under high temperatures. A higher viscosity oil, typically denoted by a larger number in the multigrade classification (e.g., 10W-40, 10W-50, 15W-50), is usually recommended. The first number (10 or 15) indicates the oil's flow at cold temperatures, whereas the second number (40, 50) represents the oil's viscosity at high temperatures. Higher second numbers ensure that the oil won't thin out as much in the heat, providing better protection for engine components. However, always consult your vehicle's manual before changing oil grades, as manufacturers specify the best oil for their engines' design and performance needs. Using an oil with too high of a viscosity can also lead to increased fuel consumption and difficult cold starts.
When picking motor oil, start by consulting your vehicle's owner manual for the manufacturer's recommendations on oil viscosity (e.g., 5W-30) and specifications. Choose between synthetic, conventional, or synthetic blend oils based on your driving conditions and budget. Synthetic oils offer the best performance and protection, particularly in extreme temperatures but come at a higher cost. Conventional oils are suitable for regular, light-duty use. Blends offer a middle ground, providing better protection than conventional oils at a slightly higher price. Also, consider if your car requires oils with specific approvals or certifications (like those from the American Petroleum Institute). Finally, consider your vehicle's age and mileage; high-mileage oils are designed for engines with over 75,000 miles and contain additives to address older engine problems.
