Viscosity Ratings Explained
Oil viscosity is an important aspect to consider when choosing the right oil for your vehicle. Viscosity is a term used to describe a fluid’s resistance to flow, and it’s measured using a scale developed by the Society of Automotive Engineers (SAE). The SAE scale assigns a numerical value to an oil’s viscosity rating, with lower numbers indicating thinner, more easily flowing oil, and higher numbers indicating thicker, more viscous oil.
For example, a 10W-30 oil has a lower viscosity rating than a 20W-50 oil. The first number (10W) represents the oil’s viscosity at low temperatures, while the second number (30) represents its viscosity at high temperatures. So, for vehicles that operate in colder climates, it’s recommended to use thicker oil with a lower first number, such as a 5W-30 or 5W-20.
On the other hand, for vehicles that operate in hotter temperatures or under heavy loads, thicker oil with a higher second number may be suitable, such as 10W-40 or 20W-50. Understanding viscosity ratings can help ensure optimal engine performance and prevent damage caused by inadequate lubrication.

Factors to Consider in Choosing Oil Weight
Choosing the right oil weight for your vehicle can be a daunting task, especially if you’re not well-versed in vehicle maintenance. Oil weight refers to the thickness of the oil, which can affect the way it lubricates engine components. For instance, if you live in a hot climate, it’s best to use a lighter oil weight, such as 5W-30, as it can circulate quickly to prevent overheating.
Conversely, if you live in a cold climate or have an older engine, a heavier oil weight like 10W-30 can provide better lubrication. Additionally, it’s important to consider the type of engine and manufacturer specifications when selecting oil weight. Following these factors can help you select the right oil weight, promoting engine longevity and improving overall vehicle performance.
Choosing the Right Oil Weight for Your Air Compressor
