Explain the Different Weights of Motor Oil

Conventional synthetic and synthetic blend the last of which combines some of the properties of the first two. Make The Switch To Castrol.

5w 20 10w 30 What Do Motor Oil Weights Mean

Enjoy Versatile Cooking With The Big Green Egg.

. The majority of engines designed before Ford had 5W-20 oil. It is correct to say 20 weight oil for 20. So you may see gear oil listed as 75W-90 which gives you both the winter and hot weights of the oil.

As there are different types of motor oils the weight of per gallon oil depends on the type of oil as well. Viscosity is a measure of how easily oil pours at room temperature. The difference in the viscosity is the reason you see multiple numbers on grades such as 5W-30.

All the numerical values are correctly referred to as weight or straight-weight oils. Multi-weight oils such as 10W-30 are a new invention made possible by adding polymers to oil. Brand new engine oils including the 0W-30 5W-30 and 10W-30 perform as single weight grade oil at fully warmed-up and operating temperature of your car.

Car Engine Oils At A Glimpse. So 0W-30 would be a better cold-weather lubricant than 5W-30. Ad Find the Right Quaker State Motor Oil and Get Engine Durability.

The higher the number on the bottle the thicker the oil. This oil weights up to 8. Within these types there are different grades or weights.

The first number indicates the viscosity of the oil at a cold temperature while the second number indicates the viscosity at operating temperature. The lower the number the lighter the weight and therefore the thinner the oil. There are three main types of motor oil.

The W signifies winter not weight. Ad Castrol Provides The Fluids The World Needs For Every Application. Oils first received this W designation from SAE in the 1950s.

The more VI additives the worse the problem which is why auto manufacturers decided to steer car owners away from motor oils loaded with VI additives like the 10W-40 and 20W-50 viscosities. The most common type of motor oil s the full synthetic motor oil. SAEs J300 standard first published in 1911 and revised numerous times since classifies oil into 11 viscosity grades0W 5W 10W 15W 20W 25W 20 30 40 50 and 60.

5W shall be called 5 weight winter-grade oil. I dont have to tell you why that is bad. According to the definition SAE J300 there are 11 single-grade oil types available.

Lower viscosity motor oils also result in better fuel economy. Its More Than Just Oil. To account for changing temperatures oil is manufactured through the use of additives so that it can have multiple grades of viscosity or multiple weights.

This has led over time to motor oil viscosity decreasing currently 5W-30 and 5W-20 are the most popular grade and 0W-20 is the fastest growing grade. The number preceding the W is a measurement of the oils flow at 0 degrees Fahrenheit. Oil weight refers to how thickthin the oil is which is the same as viscosity.

Lower viscosity oils pour with ease at a given temperature while higher viscosity oils are more. The other number refers to the oils resistance towards thinning at high-temperature conditions. These lower viscosity motor oils are needed to move through the thin engine pathways to protect and clean metal surfaces.

A 10W-30 rating means an oil has a viscosity grade of 10 in cold temperatures W. The lower the first number is the better the oil flows at below freezing temperatures. However the numbers are also temperature dependent.

Motor oil helps lubricate an engine to reduce friction and maintain smooth movement of working parts thereby increasing performance. So due to viscosity 5w20 is a thinner oil during operating temperatures whereas 5w30 is thicker during. The polymers allow the oil to have different weights at different temperatures.

Your 10W-30 motor oil can easily become a 10W-20 or even a SAE 10 10W-10 motor oil. 0W 5W 10W 15W 20W 25W 20 30 40 50 and 60. This enables the 5w20 motor oil to reach engine parts quicker and create less drag that reduces fuel economy.

The number following the W indicates the weight of the oil when hot. 5w30 motor oil the 20 indicates that the oil has a lower viscosity and is thinner at higher temperatures. When comparing 5w20 vs.

Grill Roast Smoke Bake To Perfection. In general the weight of a gallon of motor oil stays between 7-8 lbs. One weight will be a winter weight and the other will be the hot weight.
