Engine Cleaning Before Oil Change: Myth or Real Necessity?

Introduction

Changing the oil is a crucial step in ensuring the longevity and performance of your engine. But should you always clean your engine before the oil change, or is it just a marketing tactic by additive manufacturers?

💡 Some drivers believe that an oil change alone is enough, while others recommend a pre-clean to remove accumulated residues. Who’s right? Is it a real need or just a myth?

👉 In this article, we will thoroughly analyse the usefulness of engine cleaning before the oil change and separate the fact from the fiction.

1. Why does an engine get dirty over time?

An engine operates by burning fuel and circulating oil to lubricate its components. However, over time, impurities accumulate:

🔸 Combustion residues: Carbon deposits form on the valves, piston rings, and the top of the pistons.
🔸 Oxidation of the oil: Engine oil degrades, forming varnish and sludge deposits.
🔸 Mechanical wear: Fine metal particles mix with the oil, accelerating the contamination.
🔸 Poor quality fuel: Impure fuel generates deposits in the injection system and the oil circuit.

💡 A dirty engine runs less efficiently, consumes more, and wears out prematurely.

2. Is an oil change alone enough to clean the engine?

Many drivers think that just changing the oil is enough to clear the engine of impurities. This is a misconception!

🚗 Here’s why an oil change alone isn’t sufficient:

❌ Residues remain stuck to the engine walls: Used oil cannot dissolve solid deposits of carbon and sludge.
❌ Internal channels remain contaminated: Deposits build up in the oil channels and can reduce lubrication flow.
❌ The new oil gets dirty quickly: When you add new oil to a dirty engine, it is immediately contaminated by the remaining impurities.

👉 Conclusion: Without prior cleaning, the oil change only removes part of the impurities and doesn’t fully protect your engine.

3. What are the benefits of engine cleaning before the oil change?

Using an engine cleaner before the oil change offers many benefits:

✅ Removal of internal deposits: Dissolves and flushes out sludge, carbon, and oxidised residues.
✅ Optimal lubrication: The new oil stays cleaner for longer and offers better protection for the engine.
✅ Improved performance: Reduces friction and preserves the engine’s power.
✅ Reduced risk of wear: Protects sensitive components like the piston rings, valves, and turbocharger.
✅ Prolonged engine lifespan: Less contamination = less premature wear.

🔍 A clean engine consumes less and lasts longer.

4. How does an engine cleaner before the oil change work?

An engine cleaner before the oil change is an additive specifically designed to dissolve accumulated impurities in the oil system. It’s easy to use and doesn’t require any disassembly.

📌 How to use:

1️⃣ Add the engine cleaner (CLEAN Avant Vidange) to the used oil, with the engine warm.
2️⃣ Let the engine run for 10 to 15 minutes at idle speed.
3️⃣ Drain the engine oil and replace the oil filter.
4️⃣ Fill up with fresh oil suitable for your vehicle.

🚀 Result: An engine free of internal impurities and fresh oil that works at full capacity!

5. Engine cleaning before the oil change: Myth or real necessity?

What experts say:

📌 Myth: "Engine cleaning is unnecessary if you change the oil regularly."
➡️ False: Even with regular oil changes, residues accumulate that affect engine performance.

📌 Myth: "Engine cleaners are harsh and could damage the engine."
➡️ False: A high-quality engine cleaner like CLEAN Avant Vidange is designed to clean gently without damaging seals or sensitive components.

📌 Myth: "Only older engines need a cleaning before the oil change."
➡️ False: Even newer engines can get dirty, especially with short trips or urban driving.

✅ Truth: Engine cleaning before the oil change is a crucial step for an effective oil change and optimal engine protection.
