![]() ![]() The first problem you will face is debris and contamination being deposited throughout your entire engine. It can also lead to some expensive consequences. But not changing your engine oil is one of the worst things you can do for your car engine. It might be tempting to skip an oil change if you’re hard-pressed for time or money. What Happens If I Don’t Get an Oil Change? The easiest way to prevent engine sludge and keep your engine running optimally is by having regular oil changes. If sludge is still present after an engine flush, it may need to be mechanically removed. Ignoring engine sludge can expose your vehicle to extensive engine damage and removing it requires the oil to be drained and the engine to be flushed. It can also cause hard starting, overheating, and power loss. ![]() Heat from the engine causes engine sludge to harden which can cause major problems for fuel injectors, pistons, and valves. It causes blockages in the engine’s oil passages which can result in oil starvation. If oil isn’t changed it eventually thickens and becomes tar-like as it breaks down and becomes what mechanics call engine sludge.Įngine sludge sticks to engine parts as it moves around the engine and diminishes the oil’s ability to lubricate and clean. The role of oil however hasn’t changed much and it performs the same functions with greater efficiency. Modern oil is much more advanced than it used to be, which means we no longer have to change the oil every 3,000 miles. Regularly scheduled oil changes are necessary for good engine health, but have you ever wondered why changing your oil is so important? To prevent leaks and loss of engine performance, the engine oil seals microscopic spaces between the piston and cylinder to optimize engine performance. Optimizes Engine Performance: Metal surfaces are difficult to get perfectly smooth, especially when it comes to moving parts.Modern engine oils also have additives that chemically neutralize corrosion. Prevents Corrosion: While an engine is operating as normal, a coating of oil forms a barrier between components to protect them and prevent corrosion.Heat is then dispersed in the oil sump, or oil cooler if one is fitted. It also keeps temperatures constant as it flows over surfaces cooler than its usual 230 – 260F operating temperature. In fact, engine oil is responsible for up to 40% of an engine’s cooling process. Keeps Engine Temperature Constant: After an engine starts, it heats up, and one of the functions of engine oil is to remove this heat and transfer it elsewhere.This is due to dispersants that are added to engine oil at production giving it the ability to force suspension and maintain internal engine cleanliness. As engine oil circulates it suspends these contaminants within itself, preventing them from coming into contact with engine components and causing damage. Removes Contaminants: Every time an engine runs it creates by-products and contaminants like metal particles, soot deposits, acids and dust, and dirt which can wreak havoc in an engine.This results in decreased engine wear and for engine parts, increased service life. This film reduces friction by minimizing contact between engine components. Lubricates The Engine: As engine oil is pumped into an engine, it lubricates its moving internal parts, leaving a thin slippery film on the surface.Viscosity index improvers to enhance oil performance in extreme temperatures.Anti-wear agents to assist instant lubrication when the engine is started and minimize wear on engine parts that are particularly susceptible to damage.Dispersants/antioxidants to prevent impurities from being forming and building up on engine parts. ![]() Antifreeze to improve the fluidity of oil in cold temperatures.Corrosion inhibitors to protect against rust by forming a protective film.Foam inhibitors to prevent foam and bubbles forming in the oil.Oil filter: removes impurities from the oil before it is pumped through the engineĪdditionally, motor oil also has several chemical compounds that improve its performance and help keep your engine clean by removing impurities.Ĭommon additives found in motor oil include:.Oil galleries: transport oil through the engine.It does this via your vehicle’s oil system which is made up of the following parts: It also draws heat away from lubricated engine components before the oil is cooled via air in the sump before being recirculated through the engine. Oil keeps the parts running smoothly while minimizing friction and engine component wear. The primary role of engine oil is to lubricate moving parts in an engine.
