Which engine oil weight is best for my car

No more truthful words have ever been said: oil- is the lifeblood of your car’s engine. Its purpose is to lubricate the engine’s many critical parts to ensure a long, reliable life. It is also a consumable product, meaning it has a fixed replacement interval to ensure it fulfills its purpose to the best of its ability.

Like determining the law oil change interval– which is sometimes a good idea shorten— Determining what engine oil weight to change with is an important factor in proper car maintenance.

Which begs the question: what engine oil weight is best for your car?

What is Oil Weight?

When people talk about the weight of an oil, they mean the oil’s viscosity, or how fast it flows at a given temperature, as stated by The Society of Automotive Engineers (SAE). In a common, everyday multi-grade oil, the first number is the oil’s viscosity rating at -17.8 degrees Celsius (0 degrees Fahrenheit), while the second number is the rating at an engine’s operating temperature, commonly referred to as 100 degrees Celsius (212 degrees Fahrenheit). We discuss more of these finer details from oil weight in one of our many Cars 101 blogs.

There are also single-grade oils, but they are much less common and not usually found in anything that regularly rolls down public streets. Well, it depends where you are – if you live in the coastal area of ​​Orange County, California, it’s not uncommon to see old air-cooled Volkswagens rolling around with single-grade oils lubricating their little sewing machine-looking engines in the summer. It is also a popular summer weather choice for motorcyclists and tractor owners. Do you use one yourself? Leave your comment below!

But in general, multi-grade is the most common type.

Why oil weight matters

Having the correct oil weight is important as it ensures maximum engine lubrication and protection. In colder climates during the winter, a 0W-30 will provide more protection at start up than a 15W-50, although a 15W-50 will do better on a summer racetrack.

Very new engines, especially those turbocharged like the A90 Toyota GR Supra 3.0– often run very thin 0W-20 or 0W-30 multi-grade oils because of their tighter tolerances, and because they must be thin enough to meet the turbo’s lubrication needs. On the other hand, the E9XBMW M3 runs more versatile 10W-60 because it needs good boot security like the ability to keep its tense, almost race-engine-like 4.0-litre V8 amply lubricated in every scenario.

Which oil weight is best for my car?

Okay, enough chatter, this is how you find out which oil weight is best for your car: read your owner’s manual.

This sounds incredibly simple and slightly smartass-ish, but it’s the truth. In fact, most car manufacturers outline what oil weight is best for your car depending on the climate you live in. This information can also be found through a simple Google search on your phone, or in one of the big books at your favorite local auto parts store. shopkeeper.

But what about different types of oil?

There are three types of motor oil there are – synthetic, synthetic blended and conventional. In general, synthetic offers the most protection and resistance to heat and other factors that cause wear, although it is also the most expensive type. It is also more environmentally friendly, cleaner, much more resistant to degradation and silting, and more resistant to combustion/consumption.

Branding shouldn’t be a big concern when it comes to oil. As long as you use the correct oil suggested by the manufacturer with the correct certifications, it really is splitting hairs. For example, we are talking about splitting a strand of hair from a baby, a baby mouse.

In summary: Run the manufacturer’s recommended weight for the climate you live in, making sure to also pay attention to what the manufacturer suggests for type and certifications.
