The Ultimate Guide to Choosing and Changing Your 2000 Subaru Outback’s Oil

If you own a 2000 Subaru Outback, you’re probably aware that regular oil changes are essential to keep your car running smoothly. However, not all oils are created equal, and using the wrong type of oil can cause damage to your engine. In this article, we’ll guide you through everything you need to know about the type of oil your car needs, how often to change it, and how to change it yourself.

Type of Oil Needed for a 2000 Subaru Outback

The type of oil your 2000 Subaru Outback needs depends on the engine. Most 2000 Outbacks come with either a 2.2-liter or 2.5-liter engine, both of which require 5W-30 viscosity oil. Make sure to check your owner’s manual to ensure you’re using the correct oil for your engine.

Viscosity and Weight of Oil

Viscosity refers to the thickness of the oil. The first number (5 in 5W-30) indicates how quickly the oil flows in cold temperatures, while the second number (30 in 5W-30) represents the oil’s viscosity at operating temperature. For a 2000 Subaru Outback, 5W-30 is the recommended viscosity since it provides good startup flow and reduces engine wear.

Synthetic vs. Conventional Oil

Synthetic oil is made with advanced chemical processes that provide superior protection and performance compared to conventional oil. Although synthetic oil is more expensive, it lasts longer and doesn’t degrade as quickly as conventional oil, making it a better investment in the long run. However, if your car has been running on conventional oil, switching to synthetic oil might not be the best idea. Consult your mechanic before making the switch.

How Often to Change the Oil

The frequency with which you should change your oil depends on how often you drive and under what conditions. The general guideline for a 2000 Subaru Outback is to change the oil every 7,500 miles or six months, whichever comes first. If you frequently drive in dusty or mountainous areas or if you frequently tow heavy loads, you should reduce the interval to every 3,750 miles or three months.

Tools Needed to Change the Oil

Changing your 2000 Subaru Outback’s oil is a simple process that doesn’t require any advanced tools. You’ll need a wrench or socket set to remove the oil drain plug, a container to catch the old oil, a new oil filter, and the recommended amount of new oil.

Tips and Tricks for Changing the Oil

Here are some tips to make changing your 2000 Subaru Outback’s oil a breeze:

  • Warm up the engine for a few minutes before changing the oil to make the old oil flow out more easily.
  • Always use a new oil filter. It’s a small expense that can save you from costly engine damage.
  • Check the oil level after changing it to ensure you’ve added the right amount of oil. Overfilling or underfilling can cause engine damage.
  • Dispose of your old oil and filter properly. Drain the oil into a container and take it to a recycling center since it can’t be disposed of in the trash.


Q. How much oil does my 2000 Subaru Outback need?

A. The 2000 Subaru Outback with a 2.2-liter engine needs 5 quarts of oil, while the 2.5-liter engine requires 5.1 quarts.

Q. Can I change the oil myself, or should I take it to a mechanic?

A. Changing your 2000 Subaru Outback’s oil is a simple process that you can do yourself. However, if you’re not comfortable with it or don’t have the right tools, taking it to a mechanic is always an option.

Q. How do I know if my oil needs changing?

A. Your 2000 Subaru Outback might give you a warning light if the oil pressure is low or if the oil is dirty. However, it’s best to follow the recommended oil change interval to ensure your engine is running at its best.

Q. Can I use a different oil viscosity than what’s recommended?

A. It’s not recommended to use a different oil viscosity than what’s recommended since it can affect the engine’s performance and cause engine damage.

By following these simple guidelines, you can ensure that your 2000 Subaru Outback runs smoothly and efficiently. Don’t forget to check your oil regularly and change it as needed to keep your engine in top condition.
