10w40 meaning

The "10W" refers to the oil's viscosity rating in colder temperatures, while the "40" represents its rating in hotter temperatures. This means that 10W engine oil can provide sufficient protection to your engine in both cool winter mornings and hot summer afternoons. So if you want to keep 10w40 meaning engine running smoothly and efficiently, 10w40 meaning, check out our several 10W oils here at Driven Racing Oil.

These viscosity grades are commonly used in most modern passenger car engines. But what about 10W40 motor oil? Where is 10W40 oil used? A 10W oil has a viscosity grade of 10W at a low temperature and 40 at a higher temperature. What does this mean, exactly? It just behaves like a 10W weight oil when cold and like a 40 weight oil at hot.

10w40 meaning

.

AutoNation Mobile Service brings the shop to you. A 10W oil has a viscosity grade of 10W at a low temperature and 40 at a higher temperature. We carry conventional, synthetic, 10w40 meaning, and semi-synthetic 10W oils for a wide 10w40 meaning of applications.

.

In that case, 10W motor oil would technically provide better protection against engine wear contact in higher temperatures. In a 5W for example, the number before the W describes the viscosity of the oil at low temperatures. The smaller number, the 20 part of 20w describes how the oil behaves at 40 deg C and a 20w at 40 deg C is about 10 times thicker than your engine wants. A 10w is better at around 6 times thicker and a 0w is much better at about 4 times thicker. In short, if you see an expression such as 10W, the oil is a multigrade which simply means that the oil falls into 2 viscosity grades, in this case 10W and This is a fixed limit and all oils that end in 40 must achieve these limits. Characteristics of 5W Motor Oil. Skip to content.

10w40 meaning

Engine oil is the lifeblood of your car. However, there is so much to know about choosing the right motor oil for your vehicle. It needs to be the proper viscosity, or thickness, to do its job properly. The main difference between 10W and 10W motor oil is the viscosity of the oil at different temperatures. Viscosity is the measure of how thick or thin a liquid is, and it affects the flow of oil in your engine. The main difference between the oils is their viscosity at high temperatures, which refers to how thin they become when heated up. Thicker oil is also better for older engines because it can help to prevent leaks. However, more viscous oil can also make your engine work a little harder, and it can increase fuel consumption. Thinner oil is better for newer engines because it flows more easily and helps to keep the engine clean. Thinner oil can also help to improve fuel economy.

Ideal for flat Description: Well suited for a variety of hot rods and vintage vehicles and is appropriate to use in any engine that calls for a 10W grade motor oil. Sign up to get maintenance tips, news, and promos to help keep your car in tip-top shape. Using the wrong oil might affect your engine life in the long term, making it a potentially unwise trade-off. The 10W oil viscosity also often serves as an alternative for older engines with burning or oil leaking issues. Get a Quote. Like most multigrade motor oils, 10W oil can be synthetic oil, semi synthetic oil , or conventional motor oil. Consequently, 5W oil lubricates and protects the car engine better at a low temperature — especially during engine start-up in cold, winter weather. In this case, a 10W rated oil will be thicker in winter than a 5W oil. Ingredients like zinc, phosphorus, and sulfur in additives help prevent camshaft wear. This can result in better engine performance, faster acceleration, and increased power. A thinner oil is more useful at engine start-up as the oil can flow quickly for engine lubrication. Benefits of 10W Oil Improved Engine Performance 10W motor oil is formulated to withstand high engine temperatures and provide superior lubrication to vital engine components. But these elements can contaminate precious metals in a catalytic converter.

General What does 10W40 mean? Published Jay. Engine oil specification.

It does, however, influence oil viscosity. The less viscous 10W motor oil would run smoother in cooler regions. It looks at how well the oil flows at an engine running temperature of o C o F. AutoNation Mobile Service brings the shop to you. Additives help break down piston deposits, have dispersants to prevent sludge formation, and corrosion inhibitors to prevent rusting of metal surfaces. So if you want to keep your engine running smoothly and efficiently, check out our several 10W oils here at Driven Racing Oil. However, ambient temperature plays a more significant role at engine start-up. The "10W" refers to the oil's viscosity rating in colder temperatures, while the "40" represents its rating in hotter temperatures. Oils have a specified maximum viscosity at a cold temperature. USD But what about 10W40 motor oil? Here are some things to consider when deciding to use one motor oil grade over the other:. Configure Item See Details.
