Types of Oil Suitable for a 2014 Subaru Legacy

Subaru recommends using synthetic oil for the 2014 Subaru Legacy. Synthetic oil has fewer impurities, allowing it to perform better in extreme temperatures and protecting the engine better over long intervals of usage. Other alternative oils include conventional oil, synthetic blends, and high mileage oils.

Conventional oil

Conventional oil is the cheapest oil type on the market but comes at the cost of reduced performance and needing to be replaced more frequently.

Synthetic blends

Synthetic blends mix conventional and synthetic oils. They have better performance than conventional oil and come at an affordable price.

High Mileage oil

High mileage oil is suitable for cars with over 75,000 miles. It has more additives to compensate for engine wear and tear.

Synthetic oil

Synthetic oil can last longer and perform better in extreme temperatures and is Subaru’s first choice in the 2014 Subaru Legacy. However, it comes with a higher price tag compared to conventional oil, and you may have to balance the cost in relation to the difference in performance.

Characteristics of Different Types of Oil

Different types of oil have added supplements that can have an impact on your car’s overall performance. For instance, synthetic oil, being the most expensive, encourages the engine’s efficiency, decreases the engine’s temperature during extreme weather and improves fuel economy than the rest.

On the other hand, Conventional oil’s lower price tag and short lifespan may make it feel like a good deal in the moment, but it won’t be long before you notice a drag in car’s performance.

Interval for Oil Change

However, it is best to keep in mind that there may be unique cases to your car that would require you to take it to an expert.

Environmental Impact of Oil Usage in Cars

Oil products have a devastating impact on the environment. Synthetic oil is environmentally friendly, but at the same time, its manufacturer and disposal process adversely affect the environment. On the other hand, conventional oil can have adverse effects due to its pollutants in the air, water, and soil.

Tips for Checking Oil and Adding Oil to the Car

Checking your car’s oil and adding oil to it is an easy process. You should routinely check your oil levels to avoid a reduction in engine life, accelerated wear, and tear of engine parts. Keep an eye on the oil’s color to make sure it’s not too dirty or low, and change it when necessary.

To check your oil levels:

  1. Make sure your engine is off and has cooled down.
  2. Open the hood of your car and locate the oil dipstick. Usually distinguished by a yellow handle or color.
  3. Pull the dipstick out and wipe it clean with a cloth
  4. Replace the dipstick back in the engine and pull out to measure the level of oil.

To add oil to your engine:

  1. Get the recommended oil for your vehicle.
  2. Remove the oil filler cap on top of the engine.
