Chevy 350 Oil Capacity & Type [How Much Oil Does it Take?]

Key points to highlight:

  • Specifics of the Chevy 350 engine’s oil capacity: 5 quarts when including a filter change, with a recommended oil type of 5W-30 for optimal performance.
  • Older Chevy models such as LT1, L82, or L81 typically require oil with a viscosity grade of 10W30 or 10W40.

As a newbie Chevy owner, you realize that you have a lot to learn about your car. You will need to know the general functionality of essential aspects of your new vehicle. For example, you may wonder why the right motor oil matters.

Equally, you may want to acquaint yourself with the suitable oil capacity for your Chevy engine at this early stage. Engine oil remains the lifeblood of your car; it does to your vehicle what blood does to the human body.

As such, you always need to choose the right quality of oil for your car engine. Engine oil provides vital lubrication, prevents corrosion, cleans, and helps in cooling. Critically, all these functions improve and can even expand the shelf-life of your engine.

How Much Oil Does a Chevy 350 Take?

In short, the oil capacity of a chevy 350 is 5 Quartz when a filter is also added. It is recommended that you use full synthetic 5W-30 oil to ensure the engine remains in good condition and improved performance.

What Kind of Oil Does Chevy 350 Engine Need?

If your Chevy 350 engine belongs to the latest models like LT-9, L83, L98, L05, or L31, you can comfortably use 5W30.

Otherwise, for older models such as LT1, L82, or L81, you can either use 10W30 or 10W40. So, what exactly do these letters and numbers mean?

The numbers stand for the oil viscosity grade, while the W stands for winter. Therefore, 5W30 indicates that it has the Society of Automobile Engineers standard j300 viscosity of 5 during winter and 30 during warmer temperatures.

It means the type of oil your Chevy 350 uses depends on your living conditions. Hotter countries use a higher grade as colder countries need a lower viscosity grade.

The next thing you need to check on after choosing your Chevy 350 oil is whether you have an oil filter and an oil pump.

The oil pump circulates oil in and around the engine while the oil filter stops debris and built-up gunk from re-entering the engine. As tiny as 10-20 microns, the dirt particles damage the bearings, cylinders, and other moving parts by abrasion. More importantly, the Chevy 350 oil capacity remains standard at 5 quarts.

What is a Chevy 350?

A Chevy 350 remains a type of small-block V8 engine. Chevrolet started manufacturing the Chevy 350 in 1954. Also, it uses the same engine block used by other vehicles, though with a few notable variations.

In the Chevrolet family, the Chevy 350 comparatively, is a small-block engine. Also, at 262-400 cubic inches of displacement or, 4.3-6.6L machine, it’s relatively smaller than its prominent Chevrolet cousins.

During the period between 1954 to 2003, Chevrolet manufactured several V8 engines. Oldsmobile, Holden, Pontiac, Buick, and Cadillac came into prominence. However, the Chevy 305( 5.0L) and the Chevy 350(5.7L) stood out like the Chevrolet /GM standard-bearers.

Chevy 350 first appeared in the 1967 Camaro as an L-48 high-performance option. Notably, the first Chevy 350 had a capacity of 5.7L and a 3.48m, or 88.39mm stroke.

What Are the Different Types of Motor Oils?

You will find various types of motor oil that you may use for your engine needs in the market. The motor oil types can be divided into three categories as follows:

Synthetic Oil

Synthetic oil is lab-processed motor oil, streamlining its production and making it easy to control. Also, its consistent molecule size allows for less friction and more oil flow throughout the engine. Oil circulates quickly, even at cold temperatures with a high flow rate; thus, protecting the engine against abrasion.

Mineral Oil

If you frack crude oil, you create mineral oil. In the process, you purify the oil, thus separating unnecessary compounds and elements. Contrastingly, mineral oils are of lower quality than synthetic oils. The wide variation in molecule size to synthetic oils allows for greater friction that slows down oil flow in the engine.

Mixed Oils

It is a mixture of mineral oils and synthetic oils. The result is hybrid oil that captures the quality of the two oil types.

Why Does Your Engine Need Motor Oil?

Several types of motor oil exist in the market, and it can be intimidating to a new car owner trying to get the best for his/her use. But why do you need motor oil? The answer to this question may seemingly be obvious, but as a new car owner, you are better placed to have them at your fingertips.

To Prevent Engine from Breaking

Oil makes things slippery, hence acting as a lubricant to internal parts of the engine. An internal combustion engine consists of a large number of moving parts. For these parts to function optimally, these metal parts ought not to contact one another. If well lubricated, the thin film oil acts as a barrier between parts.

Coolant for Engine Parts

Another vital purpose of the motor oil is to cool the engine parts. Motor oil cools the engine parts that remain far from the water jacket. For example, in motorcycles, the transmission remains oil-based.

Catch Matter Slipping Through Piston Rings

Piston rings lack air-tight seals, leading to the combustion of products like carbon particles that slip through the ring into the piston chamber.

Over time, these carbon particles harden and will start damaging your vehicle engine. Therefore, you need to use motor oil to prevent this from happening. Grease traps carbon particles, limiting them from causing engine damage as they re-direct them into the oil filter instead.

Neutralizes Natural Acid in Engines

In gasoline, sulfur reacts with water and oxygen to create sulphuric acid. Also, sulphuric acid remains quite corrosive and very damaging to your engine. Many motor oils consist of ingredients essential for neutralizing sulphuric acid keeping your machine safe and clean.


The Chevy 350 remains to be one of the best models produced by Chevrolet. You have a variety of motor oils that you can use for this engine in the market. Significantly, you need to know the motor oil type that suits your engine. More so, your choice should be based on the weather conditions of your area of residence. Hotter areas need a higher oil viscosity grade than colder areas.
