5W-30 Oil – Buyer’s Guide

With so many brands, three oil types, and countless standards, finding the right oil is not as easy as it used to be. Here’s information that will help educate yourself and make the process easier:

What Does 5W-30 Oil Mean?

The 5W-30 indicates the oil grade or weight (viscosity). Nowadays, almost all lubricants for engines have multiple viscosities represented as ‘nW-n’ where n is a numeric number in multiples of five.

The number before W represents the viscosity at low temperatures. The lower this number is, the more fluid the oil is at low temperatures.

On the other hand, the number after the hyphen or W is the viscosity at high temperatures. So the higher the number, the less viscous the oil is at high temperatures, as you don’t want the oil to be too thin when heated.

5W-30 is an all-temperature oil with a wide temperature range. In simpler words, it’s good for winters as well as summers, offering adequate fluidity at both ends of the spectrum.

Did you know that aside from the SAE grade for viscosity, there are many other standards and certifications for engine oils? American Petroleum Institute or API certification is common for engine oils used in the US.

Other standards used around the world include ILSAC, ACEA (Europe), and JASO (Japan).

5W-30 Temperature Range

The ambient temperature range of most 5W-30 oils is from -30 degrees Celcius (-22 F) to 40 degrees Celcius (104 F).

Is 5W-30 Good for High Mileage?

Oil viscosity or grade doesn’t have much to do with the mileage of the car. It has more to do with the compatibility or the climate where the car is being driven. Nevertheless, 5W-30 grade oil is perfectly good for a high mileage engine.

There are special high-mileage engine oils available in 5W-30 grade for use in cars with mileage over 75k, and that requires this specific oil grade. If your car manufacturer recommends 5W-30, that means it recommends it for the entire life of the car, not just for when it has low mileage.

Here’s a fun fact for you car enthusiasts: most people think high-mileage cars are those with 100k miles or more on them. However, any vehicle that hits 75k miles on the odometer qualifies as a high-mileage vehicle.

5W-30 Conventional vs 5W-30 Full Synthetic Oil Comparison

One of the most common debates when it comes to engine oils is conventional vs synthetic oil. If your wondering which 5W-30 oil is best for your engine, the answer is full synthetic. Full synthetic oils are markedly more viscous and offer better temperature resistance than conventional oils.

Your vehicle will not have any issues using conventional oil if the manufacturer hasn’t officially recommended or mandated synthetic oils. However, using synthetic oils can help improve engine performance and fuel economy.

Many manufacturers have fully embraced synthetic oils. According to Consumer Reports, half the car owners surveyed by National Oil and Lube News in 2018 used synthetic or synthetic blends for engine oil.

Conventional oil does offer the price advantage as it’s typically way cheaper than synthetic oil. You can expect to get 5-quarts in under 20 bucks, whereas synthetic oils can go up to 40 bucks. This is because synthetic oils use advanced technology and are more difficult to produce than conventional oils.

What is 5W-30 Oil Used For?

The SAE grade 5W-30 oil, including conventional, semi-synthetic, and full synthetic, is not just used in gasoline car engines. Diesel engines also sometimes use 5W-30 grade, especially in colder climates.

Moreover, 5W-30 oil is also common for high-mileage vehicles.

Its use also extends to motorbikes and smaller engines, such as those in generators, lawnmowers, power washers, and snow blowers. However, you should still ensure compatibility as there are different types, standards, and uses, which means not every 5W-30 oil may be used across all possible applications.
