If you drive a 2017 Subaru, one of the best ways to keep your vehicle running efficiently for years is by using the correct oil type.
The 2017 Subaru uses 0W-20 full synthetic oil for 4-cylinder engines and 5W-30 synthetic oil for 6-cylinder models. These oils ensure smooth performance, strong protection, better mileage, and long-lasting engine health in all weather conditions.
In this complete guide, you’ll learn the recommended oil types, capacities, and maintenance intervals for the most popular 2017 Subaru models: Outback, Forester, Legacy, and Crosstrek.
Why the Right Oil Type Matters for Subaru Engines
Every Subaru engine relies on clean, properly viscous oil to lubricate its moving parts. Because Subaru uses horizontally opposed BOXER engines, oil distribution is a bit different compared to conventional inline engines. This makes viscosity and oil cleanliness especially critical.
- Viscosity (like 0W-20 or 5W-30) refers to how easily oil flows in cold and hot temperatures.
- Synthetic oil offers better resistance to thermal breakdown, ideal for Subaru’s higher compression engines.
- The correct oil type ensures improved cold starts, better fuel economy, and longer engine life.
In short: use what Subaru recommends—your engine will thank you with years of reliable performance.
Recommended Oil Types by 2017 Subaru Model
The following chart covers the most accurate and up-to-date oil specifications for the 2017 lineup:
| Model | Engine Type | Recommended Oil Type | Oil Capacity (with Filter) |
| Outback | 2.5L 4-cylinder | 0W-20 Synthetic | 5.1 qt (4.8 L) |
| Outback | 3.6L 6-cylinder | 5W-30 Synthetic | 6.9 qt (6.5 L) |
| Forester | 2.5L 4-cylinder | 0W-20 Synthetic | 5.1 qt (4.8 L) |
| Legacy | 2.5L 4-cylinder | 0W-20 Synthetic | 5.1 qt (4.8 L) |
| Crosstrek | 2.0L 4-cylinder | 0W-20 Synthetic | 4.4 qt (4.2 L) |
Quick Tip:
If you’re unsure which engine you have, check your VIN sticker or owner’s manual. The oil cap under your hood often lists the correct viscosity (for example, “0W-20”).
0W-20 vs 5W-30 — What’s the Difference?
You may notice that Subaru recommends 0W-20 for most 4-cylinder engines and 5W-30 for 6-cylinder models. Here’s why:
- 0W-20 Synthetic Oil: Designed for fuel efficiency and cold-climate starts. Flows faster at low temps, making it perfect for daily driving and moderate conditions.
- 5W-30 Synthetic Oil: Thicker at higher temperatures, giving better protection for more powerful or high-load engines like the 3.6L H6.
If you live in an area with hot summers or tow heavy loads, 5W-30 may offer a little extra protection—but always confirm it’s approved for your specific engine.
How to Check & Change the Oil in a 2017 Subaru
Changing your oil at home can save money and help you monitor your engine’s health. Follow these simple steps:
Tools & Supplies
- Correct synthetic oil (see chart above)
- New oil filter (Subaru OEM recommended)
- Drain plug washer
- Socket wrench & drain pan
- Funnel and gloves
Step-by-Step Process
- Warm the engine slightly to thin the old oil.
- Park on a level surface, engage the parking brake, and pop the hood.
- Place the drain pan beneath the oil pan and remove the drain plug.
- Let all the oil drain, then remove and replace the oil filter.
- Reinstall the plug with a new crush washer and refill with the specified quantity of new oil.
- Start the engine for 30 seconds, then turn it off and re-check the level with the dipstick.
- Top up if needed until it reaches the upper mark.
Oil Change Interval
Subaru recommends changing oil every 6,000 miles (≈ 9,600 km) or 6 months, whichever comes first. If you frequently drive short trips, tow, or operate in extreme climates, change it sooner—every 3,000–4,000 miles.
Best Oil Brands for 2017 Subaru Models
You don’t have to use Subaru-branded oil, but you should choose a high-quality full synthetic that meets API SN Plus or newer standards.
Top-rated options include:
- Subaru OEM Synthetic 0W-20
- Mobil 1 Advanced Fuel Economy 0W-20 / 5W-30
- Castrol EDGE Advanced Full Synthetic
- Valvoline Advanced Full Synthetic
- Pennzoil Platinum Full Synthetic
These oils provide excellent protection against deposits, wear, and high-temperature breakdown—all crucial for the horizontally opposed BOXER engine.
Subaru Maintenance Schedule (2017 Models)
Regular maintenance ensures top performance and prevents engine issues.
| Mileage Interval | Service Tasks |
| 6,000 miles / 6 months | Replace engine oil & filter |
| 12,000 miles / 12 months | Rotate tires, inspect brakes, check fluids |
| 30,000 miles / 30 months | Replace air filter, inspect belts, coolant, and transmission fluid |
| 60,000 miles / 60 months | Replace spark plugs (if applicable), coolant flush |
| 100,000 miles | Inspect timing components, check for oil leaks, perform full diagnostic |
Keeping up with these intervals helps maintain resale value and prevents the oil from degrading prematurely—especially important in older 2017 vehicles.
Troubleshooting: When Something Feels Off
After an oil change, if you notice:
- A burning-oil smell → Check for leaks near the filter or drain plug.
- Engine ticking sounds → Oil level may be low or the wrong viscosity used.
- Check Engine Light (CEL) → Verify oil pressure and quality; scan codes if needed.
Small mistakes can be costly, so double-check every step during changes.
Pro Tips to Extend Engine Life
- Always replace the drain plug washer—a $1 item that prevents leaks.
- Use genuine Subaru filters—they’re built to maintain oil pressure for BOXER engines.
- Check oil monthly—older vehicles may burn ½ quart between changes.
- Don’t overtighten the oil filter—hand-tight plus ⅓ turn is enough.
- Reset the maintenance reminder in your dashboard after each oil change.
