How to identify oil viscosity

A thicker oil is not always better

Oil viscosity is not a minor detail or a matter of opinion: it's a technical parameter defined by the engine's internal design. Each oil grade behaves differently during startup, circulation, and protection, and using the wrong one directly affects lubrication.

1. 5W-20
Designed for modern engines with very tight tolerances.
• Extremely fast flow during cold starts.
• Reduces internal friction and fuel consumption.
• A thicker oil prevents it from reaching critical surfaces in time.

2. 5W-30
Balanced viscosity and the most commonly used in current engines.
• Good lubrication in cold conditions and stability at high temperatures.
• Maintains correct pressure and flow rate.
• Switching to a thicker oil does not increase protection.

3. 10W-40
Higher viscosity at high temperatures.
• Increases pressure, but circulates more slowly.
• May mask noises or minor wear.
• Does not repair internal failures or compensate for incorrect tolerances.

4. 15W-40
Noticeably thicker oil.
• Slow flow during startups.
• Requires more work from the oil pump.
• In modern engines, it accelerates wear.

5. 20W-50
Very high viscosity.
• Delayed lubrication in cold conditions and limited circulation.
• Increases internal temperature and consumption.
• Using it "for protection" is one of the most harmful myths.

The correct approach is:
• Always respect the viscosity recommended by the manufacturer.
• Understand that thicker is not synonymous with better lubrication.
• Prioritize oil flow, pressure, and quality.

Professional tip: the engine doesn't need an oil that "looks thick," it needs one that circulates quickly and consistently. Real protection lies in the flow rate, not the density.
