When it comes to car maintenance, choosing the right oil is essential. At C&G Autos, your trusted local garage in Slough with over 600 glowing reviews, we’re here to offer some friendly advice to keep your engine running smoothly for years to come. One common but potentially costly mistake drivers make is using the wrong oil grade in their engines. Let’s break down why oil grade matters and what can happen if you don’t follow the recommended specifications for your car.

Why Oil Grade Matters

Every car engine has specific requirements for the oil it uses, primarily based on viscosity (thickness) and temperature performance. For instance, a common oil grade, such as 5W-30, tells you how the oil performs under different conditions. The first part, “5W,” refers to the oil’s flow in cold temperatures (winter), while the “30” refers to its thickness when the engine is hot. Using the correct grade helps maintain a balance between effective lubrication and engine efficiency.

The Risks of Using the Wrong Oil Grade

Using the wrong oil might not cause immediate issues, but over time, it can lead to several problems that may reduce your engine’s performance and longevity. Here’s what could happen:

1. Insufficient Lubrication
   If you use oil that’s too thin, it might not form a sufficient barrier between engine components, especially when the engine heats up. This could lead to “metal-on-metal” contact, causing premature wear on crucial engine parts like bearings and pistons.

2. Increased Engine Strain
   Thicker oil might seem better for protection, but it can make your engine work harder, especially in colder weather. This added strain can make it harder for your car to start in cold conditions and may result in reduced fuel efficiency. Over time, this extra resistance can cause additional wear and tear on your engine.

3. Poor Fuel Economy
   The right oil allows your engine to run smoothly, maximizing fuel efficiency. If the oil is too thick, your car needs to burn more fuel to move the engine parts, costing you more in fuel over time. On the other hand, oil that’s too thin can increase friction, also causing a dip in fuel efficiency.

4. Potential Engine Overheating
   Proper oil helps regulate engine temperature. Thicker oil may not flow freely, leading to potential hot spots and increased engine temperature, which could result in overheating. This isn’t just inconvenient – it can lead to serious, expensive damage if left unchecked.

What to Do If You’ve Used the Wrong Oil

If you’ve accidentally put the wrong oil in your car, don’t panic – this is more common than you’d think. The best course of action is to drain the oil and replace it with the correct grade, along with changing the oil filter to remove any remaining traces of the incorrect oil. Think of it like a “reset” for your engine. This simple fix can help avoid future issues and keep your car performing at its best.
