Truck engine oil is a crucial component of your vehicle’s performance and longevity. However, understanding the different types of engine oils and what they do can be confusing. In this blog, we’ll take a closer look at two important factors to consider when choosing an engine oil: viscosity and API classifications.
Understanding Viscosity
Viscosity is a measure of an oil’s resistance to flow. It’s important to choose an engine oil with the right viscosity for your truck’s engine. If the oil is too thin, it won’t provide adequate lubrication, which can lead to engine damage. If the oil is too thick, it won’t flow properly and can cause excessive wear and tear on your engine.
When you’re choosing an engine oil, you’ll see a code that looks something like “10W-30”. The first number (in this case, 10W) indicates the oil’s viscosity in cold temperatures. The “W” stands for winter, and the lower the number, the better the oil will perform in cold temperatures. The second number (30) indicates the oil’s viscosity in hot temperatures. The higher the number, the thicker the oil.
Understanding API Classifications
The American Petroleum Institute (API) has created a classification system to help consumers choose the right engine oil for their vehicle. The API classification consists of two letters, followed by a number. The first letter indicates the type of engine the oil is designed for (S for gasoline engines and C for diesel engines). The second letter indicates the performance level of the oil (for example, “J” for gasoline engines or “D” for diesel engines). The number following the letters indicates the oil’s performance level, with higher numbers indicating better performance.
Choosing the Right Engine Oil
Now that you understand viscosity and API classifications, how do you choose the right engine oil for your truck? The answer depends on a few factors, including your truck’s engine type, the manufacturer’s recommendations and the climate you’ll be driving in.
It’s important to follow your truck manufacturer’s recommendations when choosing an engine oil. They will specify the appropriate viscosity and API classification for your vehicle. You should also consider the climate you’ll be driving in, as this can impact the oil’s performance.
