How do I know the weight of my engine oil?

How do I know the weight of my engine oil?

The higher the number on the bottle, the thicker the oil. However, the numbers are also temperature dependent. A 10W-30 rating means an oil has a viscosity grade of 10 in cold temperatures (“W” stands for “winter”), and 30 in warm temperatures.

What is my oil capacity?

One of the first places to look is your owner’s manual. In the Table of Contents, you’ll find a listing for “Vehicle Specifications”. Once you turn to that page, look for a heading that says “Lubrication System”. That will tell you the oil capacity of the engine if you completely drain and refill it.

Can I use 10w30 instead of 5w20?

Originally Answered: Can I put 10w30 instead of 5w20? You can, but you will get worse mileage, and in most cases shorten the life of your engine, as it will take longer to pump up pressure for your bearings and lifters, and won’t spray your lower cylinders for an extra second or so on each cold start.

Can 5W40 be used instead of 5w30?

There’s not going to be much functional difference between a 5w-30 and 5w-40 as there’s a lot of functional overlap in the recommendations. The lower weight might yield better efficiency under light load operating conditions, but higher weight might yield better protection under higher load operating conditions.

What’s the difference between 5W 20 and 5W 30?

5w30 motor oil, the 20 indicates that the oil has a lower viscosity and is thinner at higher temperatures. So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures.

Whats thicker 5w20 or 10w30?

5w20 is thinner at lower temperatures, whereas 10w30 is thicker at lower temperatures. 5w20 is better for cold-weather starting, whereas 10w30 is better for sealing action.

Can I put 10w30 in 5W 30?

Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.

How do I know what type of oil is right for me?

You can use the vehicle selector to find the right oil for your vehicle, or your owner’s manual should also provide a recommendation for the appropriate type and weight of oil required for your application. O’Reilly Auto Parts stocks name-brand oils you trust to keep your vehicle running at peak performance and minimize wear.

What is motor oil viscosity and how to measure it?

It changes with temperature, shear rate, pressure, and thickness. Oil viscosity is graded by measuring the time it takes for a standard amount of oil to flow. Motor oil viscosity is a common term we need to understand completely, and it refers to the ability of an oil to flow.

How do I know when to change the oil in my car?

Many modern vehicles use sensors to detect when the engine oil needs to be changed, and will alert you with a light or message on the dash when it is time to change the oil. It is best to always observe the oil change interval specific to your vehicle to ensure the longest engine life.

What is oil weight and why does it matter?

Oil weight is the term used to describe the viscosity of an oil, which indicates how well an oil flows at a specific temperature. The lower the oil weight number, the more quickly the oil flows.
