My Buying Guide on ‘Engine Oil Sae 15W 40’

When it comes to taking care of your car’s engine, choosing the right engine oil is crucial. After all, the engine oil is responsible for lubricating and protecting the internal components of your car’s engine, ensuring its smooth and efficient performance. One type of engine oil that I highly recommend is Sae 15W 40. In this buying guide, I will share my personal experience and tips on purchasing the best Sae 15W 40 engine oil for your car.

What is Sae 15W 40 Engine Oil?

Before we dive into the buying guide, let’s first understand what Sae 15W 40 engine oil is. The Society of Automotive Engineers (SAE) has created a classification system for engine oils based on their viscosity, which refers to how thick or thin the oil is. “SAE” stands for Society of Automotive Engineers while “15W” and “40” refer to the oil’s viscosity rating at different temperatures.

The number before “W” (winter) indicates the viscosity at low temperatures, while the number after it indicates the viscosity at high temperatures. In simpler terms, SAE 15W refers to a multi-grade oil that performs well in both cold and hot weather conditions.

Benefits of Using Sae 15W 40 Engine Oil

Now that we know what SAE 15W 40 engine oil is let’s take a look at its benefits:

– Improved Cold Start: The “W” in SAE 15W stands for winter and indicates its ability to flow easily in cold temperatures. This ensures an easy start-up even in freezing weather conditions.
– Better Fuel Efficiency: Due to its low viscosity, SAE 15W 40 offers less resistance within the engine, resulting in improved fuel efficiency.
– Enhanced Engine Protection: The high viscosity rating of SAE 15W ensures proper lubrication and protection for your car’s internal components.
– Suitable for Various Weather Conditions: Whether you live in colder or hotter regions, SAE 15W can withstand extreme temperatures without compromising its performance.

Factors to Consider When Buying Sae 15W Engine Oil

Now that you know about its benefits let me share some factors that you should consider when purchasing SAE 15W engine oil:

– Vehicle Specifications: Before buying any engine oil, it’s essential to check your car’s manufacturer manual for their recommended specifications. This includes viscosity ratings like “SAE,” such as “API,” which stands for American Petroleum Institute.
– Quality: Always opt for high-quality brands when it comes to purchasing engine oils as they ensure proper lubrication and protection for your car’s engine.
– Price: While quality should be your priority when buying any product, it doesn’t mean you have to overspend. Do some research and compare prices among different brands while keeping in mind their quality.
– Usage: Consider how often you use your car and under what conditions when selecting an appropriate drain interval for your chosen brand of SAE 15 W.

How to Change Your Engine Oil with Sae 15w

Once you have purchased your preferred brand of SAE 15 W engine oil, follow these steps to change your car’s old oil:

1. Park Your Car on a Flat Surface: Make sure your car is parked on level ground before changing the oil.

2. Drain Old Oil: Locate the drain plug underneath your car and place an empty pan underneath it before unscrewing it with a wrench. Allow all old oil to drain out completely before replacing the drain plug.

3. Replace Oil Filter: Locate the old filter (usually near or above the drain plug) and replace it with a new one.

4. Refill with New Oil: Using a funnel, refill your car with new SAE 15 W engine oil according to its recommended capacity mentioned in your vehicle manual.

5. Check Oil Levels: After refilling with new oil, wait a few minutes before checking if it has reached its recommended level using a dipstick.

In conclusion, choosing the right type of motor oil can significantly impact your vehicle’s performance and longevity.
