What Grade Oil To Use In My Car

How do I know which oil to put in my car?

Choose an oil with the vehicle manufacture’s recommended viscosity rating (check your owner’s manual). Viscosity is an oil’s ability to flow at different temperatures. The two most common viscosities (a.k.a. weights) are SAE 5W-30 and SAE 10W-30. The lower the number, the thinner the oil.

Does it matter what grade of oil I put in my car?

As long as the grade and ACEA specification is correct, you should be fine. However, David Wright of the United Kingdom Lubricant Association recommends choosing reputable manufacturers. Some firms will blend more advanced, expensive oils that exceed the specifications on the packaging.

Should I use 5w30 or 5w40?

5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.

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.

What happens if I put the wrong oil in my car?

Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.

Is Full synthetic oil Better?

Yes, synthetic oil is better for your engine than conventional oil. Synthetics use higher quality base oils as compared to the less-refined base oils used in conventional oils which makes conventional oils: Less chemically stable. Oxidize and acidify more easily.

Does type of oil really matter?

The most important thing is to use oil that’s the right thickness, or viscosity, for your car’s engine. Oil that’s too thick or thin won’t provide the necessary protection for your engine, which can result in costly damage. The standards required for your car will also be listed in your owner’s manual.

What does 5w30 mean?

5w30 motor oil has a winter viscosity grade of five, meaning it’s less viscous (less thick) at very low temperatures compared to, say, 10w30. It has a hot viscosity grade of 30, which means it is less viscous at high temperatures than an oil such as 5w50.

Does the brand of oil matter?

As long as the oil weight and certifications match what your car needs, there is no point in paying extra for a brand name. Blackstone Laboratories has performed oil analysis on hundreds of thousands of vehicles.

What happens if I put 5w40 instead of 5w30?

In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.

Can I switch from 5w40 to 5w30?

In most cases, if they recommend SAE 5W-40, then SAE 5W-30 may cause problems with wear or even engine damage. SAE 5W-40 will always be “Thin” enough at any temperature, but SAE 5W-30 may be too “Thin” at high temperatures.

Can I run 5w40 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.

Is it OK to use 5w30 instead of 5W20?

Can You Use 5w30 Instead Of 5w20. It is not recommended. Although they both have the same winter rating of 5, the thickness (viscosity) of 5w30 is a bit higher than 5w20. That means your engine’s at stake for using the high viscosity oil.

Is 5W20 good for summer?

5W20 yeah it is like water, good for winter, but not as good in summer, when it gets 110F. Although 5w20 is like water, but it is holding together.

Can I put 5W20 oil instead of 5w30?

Mixing 5W-20 and 5W-30 (or any other oils for that matter) may lead to faster wear and tear of your engine and eventually cause problems with the basic functioning of critical engine parts. And even if your engine allows it, you won’t get any noticeable results by mixing different viscosity grade oils.

What happens if I put 10W40 instead of 5W-30?

If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

Can I put synthetic oil in my car after using regular oil?

yes. If you don’t have a choice, adding synthetic oil to regular oil can help you out in a pinch. Since motor oils are generally made from the same ingredients (base oil and additives), they are typically compatible when mixed.

Can you switch oil types?

Myth: Once you switch to synthetic oil, you can never switch back. This is one of the most persistent myths about synthetic oil—and completely untrue. You can switch back and forth at any time. In fact, synthetic blends are simply a mixture of synthetic and conventional oils.
