Here are a few things to consider when choosing motor oil for your vehicle:
Viscosity: The viscosity of motor oil refers to its thickness or flow resistance. The first number in the viscosity grade (10W) indicates the oil's viscosity at low temperatures, while the second number (40) indicates its viscosity at high temperatures. A lower first number indicates better cold-weather performance, while a higher second number indicates better high-temperature performance.
Mileage: As vehicles accumulate mileage, their engines may start to wear and consume more oil. Using a higher viscosity oil (such as 10W-40) can help to slow down oil consumption and maintain adequate lubrication in older engines.
Climate: If you live in a region with extreme temperatures, it's important to choose a motor oil that is suitable for those conditions. For example, if you live in a very cold climate, you may want to use an oil with a lower first number (such as 5W) to ensure good cold-weather performance.
Manufacturer's Recommendations: It's always a good idea to refer to your vehicle's owner's manual for the manufacturer's recommended motor oil viscosity grade. This recommendation may vary depending on factors such as the engine type and climate.
Based on these considerations, a 10W-40 motor oil is generally a suitable choice for a 1996 Mazda B2300 with over 154,000 miles. However, it's always a good idea to consult your vehicle's owner's manual or a qualified mechanic to confirm the best motor oil for your specific vehicle and driving conditions.
