Engine oil numbers what do they mean

An engine oil analysis can give you a look deep inside the workings of the engine without you having to take it apart. Naturally, a lab report that comes back showing lots of metal particles may be a sign that you should avoid taking that vehicle home.

What do the numbers and letters mean? The next topic is the numbers and letters , which should never be overlooked. You might have seen '10W-40' or '5W-  Most motor oils are multigrade, for example '5W-40', meaning that they are able to The second and higher number indicates the lubricant's viscosity under You would be wise to check for faults, taking into account the type of engine, its age  engine oil? What is synthetic engine oil? Learn from Shell why it's essential that you get your engine oil specification right. What do the oil numbers mean? Manufacturers label the engine oils they produce using codes and numbers that puzzle many car owners. Motor oil should feature: They are also divided into classes: B1 and B5 mean fuel economy, while В3 and В4 are regular products. Viscosity Significance. Why it is important to ensure that a petroleum product has a correct viscosity. 3 Oct 2013 What do all those numbers and letters mean, and are all brands the same? Are you puzzled about the types of motor oil available? Wondering  However Bardahl motor oil always means: exceptional good lubrication of your car, A number of problems arise if you do not observe the aging of oil. The first  

The first number describes viscosity at low temperatures. The second number refers to viscosity at normal engine operating temperatures. Some examples: the “5” in a 5W-30 motor oil will protect an engine down to an air temperature of about -25 degrees Fahrenheit.

As for the numbers and what they mean, the numbers are the "viscosity" of the oil. Viscosity refers to the thickness of the oil, lower numbers are thinner, higher numbers are thicker. More appropriately the viscosity number is the amount of a given oil that can flow through a given oriface within a fixed amount of time which determines the viscosity number. The first number describes viscosity at low temperatures. The second number refers to viscosity at normal engine operating temperatures. Some examples: the “5” in a 5W-30 motor oil will protect an engine down to an air temperature of about -25 degrees Fahrenheit. CODE BREAKING A close look at engine oil labels and understanding the abbreviations. By Bruce W. Smith / Editorial Services. No matter what brand or type of oil container you grab, there’re a number of symbols and abbreviations listed on the label that help you make the right oil choice. Motor oil lubricates engine components and cuts down on friction. Friction causes increased heat (which increases wear) and the engine parts to slow down. Motor oil creates a small barrier or film between the parts in order for them to slide past one another. The slippery portion of parts increases efficiency, An engine oil analysis can give you a look deep inside the workings of the engine without you having to take it apart. Naturally, a lab report that comes back showing lots of metal particles may be a sign that you should avoid taking that vehicle home.

The higher numbers of a gear oil (e.g., 75W-140) do not mean that it has higher viscosity than an engine oil. In anticipation of new lower engine oil viscosity grades, to avoid confusion with the "winter" grades of oil the SAE adopted SAE 16 as a standard to follow SAE 20 instead of SAE 15.

What's written on your oil bottle, and what does it mean? This post may seem like going back to basics but I'm constantly surprised by the number of people who 

If your car calls for a 5W-30 or a 10W-30, but you live in an extremely cold climate, then you can use a 0W-30; choosing a “0W” means the oil will still pump at -40°F, and the “30” means the oil will provide the same high temperature viscosity. Lower viscosity “0W” oils can also help provide better fuel economy,

Manufacturers label the engine oils they produce using codes and numbers that puzzle many car owners. Motor oil should feature: They are also divided into classes: B1 and B5 mean fuel economy, while В3 and В4 are regular products. Viscosity Significance.

Wondering  However Bardahl motor oil always means: exceptional good lubrication of your car, A number of problems arise if you do not observe the aging of oil. The first   29 Jul 2016 Confused when it comes to buying engine oil? Multigrade oils span a wide viscosity range and consist of two numbers on the label e.g. 10W-30. as measured at 100°C. Therefore, an oil with a 10W-30 grade means it is a 10- weight oil, which will not thin any further than a 30-weight oil would when hot. Your vehicle shows engine oil life as a percentage. Percentage of remaining life, there is sometimes a letter and/or a number displayed-what do they mean? Simply put viscosity is a physical property of a fluid or gas that reflects it's tendency to flow. What do the SAE numbers on a container of motor oil mean?

A: That's the viscosity range of the oil, i.e., how thick it is. 20W means that this oil behaves exactly like a 20 weight oil at 0F, and behaves like a thicker 50 weight oil  5 Oct 2016 What do the combination of numbers and letters on a bottle of oil actually mean? engine-oil-cp4l The numbers on the side of any bottle of  What do the numbers and letters mean using the example SAE 20w/50, API - SJ/CF is a viscosity numbering system used to identify the 'thickness' of an oil or it's The second part,CF, is a diesel engine oil rating, 'C' being diesel and 'F'  10 Dec 2014 Those numbers that don't have the W were tested at 210°F, the To interpret the viscosity 5W-30, it means that an SAE 5 motor oil can perform
