What you need to know before you start

A Subaru Crosstrek oil change follows the same basic steps as most vehicles, but Subaru engines have a few quirks worth knowing about before you begin. The most important: Crosstrek models use different oil capacities and filter locations depending on the year and engine type, so you need to check your owner's manual or the sticker under your hood for the exact amount and grade your engine needs.

Most Crosstrek owners change oil every 6,000 miles if they use synthetic oil, or every 3,000 to 5,000 miles with conventional oil. Subaru's official recommendation varies by model year and driving conditions, so check your manual for your specific vehicle. The job takes about 30 to 45 minutes if you have done it before, or an hour to 90 minutes if this is your first time.

Key Takeaways

  • Subaru Crosstrek models from 2013 onward use either a 2.0-liter or 2.5-liter engine, and each requires a different oil capacity and filter type.
  • You will need an oil drain pan, a wrench or socket set, an oil filter wrench, a jack and jack stands (or ramps), and the correct oil grade and amount for your model year.
  • The oil drain plug is located on the underside of the engine, and the filter sits on top of the engine in most model years, making it easier to reach than in some other vehicles.
  • After draining old oil and replacing the filter, you refill through the top of the engine, then run the engine for a few seconds and check the level on the dipstick before driving.

Gather the right tools and materials before you start

You will need an oil drain pan large enough to hold at least 5 quarts, since Crosstrek engines hold between 3.7 and 5.1 quarts depending on whether you are also replacing the filter. A socket wrench set with metric sockets (usually 17mm for the drain plug) is standard. An oil filter wrench makes removing the old filter much easier — the band-style or cup-style wrenches work well for Crosstrek filters.

You will also need a jack and jack stands, or ramps, to safely lift the front of the vehicle so you can reach the drain plug and filter. Never work under a car supported only by a jack. A new oil filter (the correct part number for your model year) and the right amount and grade of oil are essential — check your owner's manual or the sticker inside the driver's door jamb for the exact specification. Most Crosstrek models use 0W-20 or 5W-30 synthetic oil, but this varies by year.

How to drain the old oil safely

Lift the front of the vehicle using a jack, then find it with jack stands on both sides. If you use ramps, drive slowly onto them and engage the parking brake. Locate the oil drain plug on the underside of the engine — it is a bolt that sticks down from the oil pan. Place your drain pan underneath it, then use your wrench to turn the plug counterclockwise until it comes free by hand.

Let the old oil drain completely into the pan. This takes 5 to 10 minutes. While you wait, wipe the drain plug clean with a rag and inspect the rubber washer on the bottom of the plug. If it looks cracked or flattened, replace it with a new one (these are inexpensive and often come with the new oil filter). Once the oil has stopped dripping, wipe the drain plug threads clean and screw the plug back in by hand, then tighten it with your wrench — snug but not so tight that you strip the threads.

Locate and replace the oil filter

The oil filter on most Crosstrek models sits on top of the engine, making it more accessible than in many vehicles. It looks like a cylindrical canister about 3 inches tall. Place your drain pan underneath it to catch any remaining oil, then use your oil filter wrench to turn it counterclockwise until it spins free by hand. Unscrew it the rest of the way and set it aside.

Before installing the new filter, wipe the rubber sealing surface on the engine with a clean rag to remove any old oil or debris. Take the new filter and explore a thin layer of fresh oil to the rubber gasket on the top of the filter — this helps create a good seal and makes removal easier next time. Screw the new filter on by hand until the gasket touches the engine, then turn it an additional three-quarters of a turn. Do not use the wrench to tighten it; hand-tight is correct.

Refill with fresh oil and check the level

Lower the vehicle back to the ground. Locate the oil filler cap on top of the engine — it usually has an oil can symbol on it. Unscrew it and set it aside. Pour in the amount of oil specified in your owner's manual, usually between 3.7 and 5.1 quarts depending on whether you replaced the filter. Pour slowly and check your progress to avoid overfilling.

Once you have added the oil, screw the filler cap back on. Start the engine and let it run for about 30 seconds, then turn it off. Wait a minute for the oil to settle, then locate the dipstick (usually a yellow or orange handle on the side of the engine). Pull it out, wipe it clean on a rag, reinsert it fully, then pull it out again to check the level. The oil should reach the full mark. If it is low, add a small amount more and recheck. If it is overfull, drain a little out through the drain plug.

Dispose of old oil properly

Never pour old oil down a drain or into the ground — it contaminates water supplies and harms wildlife. Most auto parts stores that sell oil will take used oil for free, even if you did not buy it from them. Some will also take used oil filters. Call ahead to confirm their policy. You can also check Earth911.org or call your local waste management department to find a disposal location near you.

If you have a large quantity of old oil, some recycling centers will take it as well. Keep the oil in a sealed container until you can drop it off. Many people keep a plastic jug or old milk carton for this purpose.

Common mistakes to avoid on a Crosstrek

The most frequent error is using the wrong oil grade or capacity. Subaru engines are sensitive to oil viscosity, and using 10W-30 instead of 0W-20 can affect fuel economy and engine performance. Always check your manual or the sticker in the door jamb, not just what the previous owner used. Another common mistake is overfilling the oil — even a half-quart too much can cause the engine to foam and lose pressure.

A third mistake is over-tightening the drain plug or filter. The drain plug threads are aluminum and strip easily if you force them. The filter gasket is designed to seal at hand-tight plus three-quarters of a turn — more pressure does not improve the seal and makes removal harder next time. Finally, do not forget to check the oil level after the first drive. Sometimes the level drops slightly as the new filter fills with oil.

Frequently Asked Questions

How often should I change the oil in my Crosstrek?

Subaru recommends every 6,000 miles with synthetic oil for most recent model years, or every 3,000 to 5,000 miles with conventional oil. Older Crosstrek models (2013–2015) may have different intervals. Check your owner's manual or the maintenance schedule sticker under the hood for your specific year and engine type.

What oil does a Subaru Crosstrek use?

Most Crosstrek models use 0W-20 synthetic oil, but some years use 5W-30. The correct grade is printed on a sticker inside the driver's door jamb and in your owner's manual. Using the wrong viscosity can affect engine performance and fuel economy, so always verify before you buy.

Can I change the oil myself if I do not have a garage?

Yes, as long as you have a safe way to lift the vehicle. Ramps work well and are less expensive than a jack and stands. Make sure the ground is level and solid, and never work under a vehicle supported only by a jack. If you live in an apartment or do not have access to a safe workspace, a quick-lube shop or dealership is a better option.

What should I do if I spill oil on the driveway?

Sprinkle cat litter, sand, or an absorbent powder on the spill when ready to soak it up. Let it sit for 15 to 30 minutes, then sweep it into a bag and dispose of it as hazardous waste. For large spills, contact your local environmental agency for guidance on cleanup and disposal.

Do I need to reset anything after an oil change?

Most Crosstrek models do not require a reset after an oil change. Some newer models have a maintenance reminder light that you can reset through the dashboard menu — check your owner's manual for the exact steps. The dealership can also reset it if you are unsure how.
