It also prevents engine damage caused by friction and provides oxidation resistance.Īpart from these essential functions, 10W-30 oil also features: This lubricant gives maximum protection to engine parts like pistons to prevent engine deposits. This capacity makes it ideal for heavy-duty diesel engines since it is a slightly thicker oil that can withstand a heavy load. It can also work well under high temperature and pressure environments in hotter climates and adhere to the engine without thinning out. What Is 10W-30 Oil Used For?ġ0W-30 has a great capacity to withstand hotter temperatures without compromising the quality of the engine performance. Keeping that in mind, let’s look at the uses of 10W-30 multi-grade oil.
For maximum protection in cold temperatures, look for a thinner oil like 0W-20 or 5W-30. So, it may not perform as well in freezing climates and lower temperatures. However, it’s a comparatively thicker oil film and has a consistency similar to grease. This capacity makes 10W-30 oil pretty stable at higher temperatures and pressure, and can run through critical engine parts without causing too much friction. Meaning, 10W-30 motor oil acts like an SAE 10W weight oil under 0☌ (32☏) and an SAE 30 oil at 100☌ (212☏).ġ0W-30 oil can survive at temperatures as low as -13☏ and as high as 86☏. The higher these digits are, the better they’ll hold up under a hot operating temperature. The numbers after it denote the oil viscosity at high temperature settings. The lower this number is, the better your engine oil will perform in cold temperature environments.
The numbers before the ‘W’ represent the oil’s winter-grade viscosity. A lubricant’s viscosity index is related to the viscosity change rate due to a temperature change. The numbers refer to the oil’s viscosity index. Engine oil grades are a scale developed by the Society of Automotive Engineers (SAE) to describe oil viscosity.
In this case, the SAE (Society of Automotive Engineers) 10W and SAE 30 weight oil. You, too, can increase your car’s performance by knowing more about engine oils and their classification.Ī multi-grade oil carries the properties of two different viscosity grade oils. Engine oils are becoming a vital tool for automotive engineers to help them meet fuel efficiency and emissions requirements.
