THE KNOWLEDGE

Oil System

You don't need to be a professional mechanic to acknowledge the fact that a vehicle's engine has numerous moving parts. When these parts come into contact with each other while in motion, friction occurs, which lowers their efficiency and increases their wear and tear rate. This is the purpose of the oil system in your vehicle, to act as a lubricant and reduce the damaging effect that friction has on your engine.

Components of the Oil System

While there might be slight differences between different manufacturers, the main components that are standard in all vehicles are:

- The Oil Pan/Sump

This is the reservoir that holds the engine oil. The oil that gets into the engine comes from the oil pan, and after it circulates through the engine it returns back to the oil pan ready to its next cycle.

- The Oil Pump

Since gravity is working against the oil circulation, an oil pump is necessary to provide the power that will push the oil and create the required pressure to move it throughout the engine.

- The Pressure Valve

Once the oil is pumped from the sump, it is restricted for a while so that it builds up enough pressure to propel it throughout the engine. Once this pressure is achieved, the pressure valve opens to allow the pressurized oil into the engine.

- The Oil Filter

Once the oil has gone through the engine, it picks up dust, grime and other particles that were hidden within the engine's crooks and crannies. The oil filter removes these impurities before the oil is recycled back into the engine.

- The Pickup Tube

This is the piping that connects the oil pan/sump with the pressure valve. Once the engine is switched on, the oil pump pushes the oil through the pickup tube on its way towards the engine.

- Galleries

The galleries are a series of holes within the engine that allows the pumped oil to access all the engine components that require lubrication. Thanks to the pressure created by the oil pump, in conjunction with the pressure valve, the oil that enters the engine has sufficient pressure to pass through all the galleries and lubricate the engine's moving parts.

What is the Purpose of Oil in the Engine?

- Lubrication

This is the main purpose of engine oil, to lubricate the moving parts within the engine. A well-lubricated engine does not have much friction which reduces the amount of energy that is required to function. This increases engine performance and improves the overall vehicle engine efficiency. Lubrication also reduces the wear and tear that comes naturally when moving engine parts come into contact. The main engine block which houses the pistons and the crankshaft are particularly prone to damage if they are not sufficiently lubricated, this is where a performance oil system come into play removing the unnecessary risk to valuable engine parts.

- Temperature Regulation

One of the side-effects of friction within the engine is overheating. A well-lubricated oil system ensures that this friction generated heat is not produced which keeps the engine temperatures cooler. Oil is also an excellent conductor of heat. As the cool oil passes through the engine, it absorbs some of the heat generated in the engine further cooling it.

- Removing Dirt and Debris from the Engine

As the engine moves, it usually collects dust, dirt and other debris. These are usually washed away by the oil as it passes through the small holes and galleries within the engine. The oil filter ensures that this dirt is not returned back to the engine during the next oil cycle, thus keeping the engine clean. Debris buildup within the engine affects the overall efficiency and performance of your vehicle.

Aftermarket Improvements to the Oil System

The aftermarket parts that can improve the performance of your vehicle include:

- Oil Catch Tanks

During the combustion process, the combustion cylinder and piston need to be well-lubricated to function properly. Unfortunately, some of this oil ends up getting mixed with the fuel-air mixture being combusted, adding impurities to the exhaust fumes produced. Without an oil catch tank, this oil will be pushed into the exhaust system and will cause clogging over time. In high-performance vehicles, not only is the combustion rate increased, but any blockage in the exhaust will lead to reduced efficiency. The catch tank stores this oil before it enters into the exhaust system.

- Oil Drain Plugs

When you go for an engine change, the oil that is stored in your sump needs to be drained; this is done via the oil drain plug which is located below the sump. High-performance vehicles usually require a reinforced drain plug that will not cause leakage under heavy use.

- Dry Sump

Most stock cars use a wet sump which stores all the oil being used in the engine. A dry sump utilizes an additional oil reservoir which allows the sump to be much smaller. It is referred to as the ‘dry' sump since it is completely drained when the oil is being pumped into the engine. Its smaller size allows the engine to sit lower and creates a lower center of gravity that improves handling and cornering at high speeds.

- Oil Coolers

In a high-performance engine, the oil tends to heat up much faster due to the increased power output. Engine coolers are usually installed to keep the oil from getting overheated, and losing its effectiveness. Engine coolers are usually installed to regulate the temperature of heating oil, although there are some that can regulate the transmission oil temperatures as well.

Frequently Asked Questions about Oil System

What does the oil system do in my car?

Your car's oil system is much more than just 'oil changes'. It’s the lifeblood of your engine, responsible for lubrication, temperature regulation and cleaning. The oil itself reduces friction between moving parts – think pistons sliding inside cylinders. Less friction means less wear and tear, better performance, and improved fuel efficiency.

It also carries away heat generated from combustion, preventing overheating. Plus, the oil picks up dirt, debris and metal particles, transporting them to the oil filter where they’re removed before the oil is recirculated. A healthy oil system keeps everything running smoothly.

Essentially, it's a closed-loop system with an oil pan, pump, filter, and network of galleries ensuring every vital engine component gets the lubrication it needs.

What are some aftermarket upgrades for improving my vehicle’s oil system?

If you're serious about performance, several aftermarket upgrades can boost your oil system. Oil catch cans prevent oil from entering the exhaust, keeping emissions clean and maintaining engine efficiency.

Upgraded oil drain plugs with stronger seals are a must for high-performance builds, preventing leaks under stress. Dry sump systems, while complex, lower the engine's center of gravity for better handling on track. And finally, adding an external oil cooler is essential if you push your engine to its limits, ensuring consistent oil temperature and lubrication.

Let’s be honest – these aren’t cheap. But a robust oil system is crucial for reliability when building a high-horsepower engine.

How does engine oil help regulate temperature?

Engine oil isn’t just a lubricant; it plays a crucial role in temperature management. Friction generates heat within the engine, and oil helps absorb and dissipate that heat.

As the oil circulates, it carries heat away from critical components like pistons and bearings. It also acts as a coolant itself, transferring heat to the oil pan and then to the outside air (or an oil cooler).

A well-maintained oil system keeps temperatures stable, preventing overheating and potential engine damage. Using high-quality synthetic oils further enhances this thermal protection.

What are some aftermarket upgrades I can make to my oil system?

If you’re building a performance engine, the stock oil system might become a bottleneck. Several upgrades address these limitations.

Oil catch cans prevent oil from entering the intake and exhaust, improving combustion efficiency and reducing carbon buildup. Upgraded oil drain plugs offer improved sealing and durability for frequent oil changes. Dry sump systems relocate the oil reservoir externally, allowing for lower engine mounting (better handling) and preventing oil starvation during aggressive driving.

Finally, an oil cooler helps dissipate heat in high-stress situations like track days or towing. Choosing the right upgrades depends on your specific goals – street performance versus all-out racing.

How does an oil system work?

The oil system is your engine’s lifeblood. It works by circulating oil throughout the engine to lubricate moving parts, reduce friction and heat, and remove debris.

Here's a simplified breakdown: The oil pump draws oil from the oil pan (reservoir) and sends it under pressure through galleries – tiny channels within the engine block. This pressurized oil reaches vital components like pistons, crankshaft, camshaft, and bearings, creating a protective film that minimizes wear.

The oil then passes through an oil filter to remove contaminants before returning to the pan for recirculation. A healthy system maintains constant lubrication even at high RPMs or under heavy load. Think of it as a circulatory system keeping your engine's organs functioning smoothly.

How much is an oil system repair?

The cost of an oil system repair varies wildly depending on what’s broken. A simple oil leak from a worn seal might be a $100-300 fix, requiring just parts and labor to replace the gasket.

More serious issues like a failing oil pump ($400-$800) or a cracked oil pan ($500+) will obviously cost more. A complete overhaul – including replacing the pump, seals, cooler (if equipped), and filter – could easily exceed $1000.

It’s crucial to get a proper diagnosis from a qualified mechanic. Ignoring an oil system problem can quickly lead to catastrophic engine failure, costing thousands in repairs or even requiring a complete engine replacement.

What is the oil system called in a car?

The entire network responsible for lubricating your engine is generally referred to as the 'oil system'. But it’s not one single component – it's an integrated collection of parts. You’ll often hear mechanics refer to it by its core function: the lubrication system.

Key components include the oil pan (where the oil is stored), the oil pump (which circulates the oil), the oil filter (to remove contaminants), and a network of galleries – tiny channels that deliver oil to every moving part. Some high-performance cars also feature additions like oil coolers or dry sump systems.

Understanding it’s a *system* is crucial. A failure in one area impacts the whole thing. Ignoring an oil change, for example, isn't just about dirty oil; it stresses the pump and clogs the filter, ultimately damaging your engine.
