Subaru Outback Oil Capacity by year and engine
Match the model year and engine before comparing oil capacity in US quarts. The table reports the compiled with-filter quantity. It is not a dry-engine fill or a guarantee that the same amount applies to another engine in the range.
| Year / configuration | Oil Capacity | Manufacturer references |
|---|---|---|
| 2018 · 2.5L AWD CVT | 5.1 qt · SAE 0W-20 synthetic | Reference 1 · 2026-09-05 |
| 2018 · 3.6L AWD CVT | 6.9 qt · SAE 5W-30 | Reference 1 · 2026-09-05 |
Compare oil capacity across other models. Not published means the field has no compiled value for that configuration.
Subaru Outback Torque Specs by year and engine
This table covers wheel-fastener tightening torque in foot-pounds. It does not cover cylinder-head bolts, brake calipers or suspension fasteners. Those jobs need their own procedure and torque specification.
| Year / configuration | Torque Specs | Manufacturer references |
|---|---|---|
| 2018 · 2.5L AWD CVT | 88.5 ft-lb | Reference 1 · 2026-09-05 |
| 2018 · 3.6L AWD CVT | 88.5 ft-lb | Reference 1 · 2026-09-05 |
Compare torque specs across other models. Not published means the field has no compiled value for that configuration.
Subaru Outback Towing Capacity by year and engine
A towing-capacity search needs more than a year and model. Engine, drivetrain, axle ratio, cab, towing equipment and trailer brakes can affect the manufacturer's limit. A single maximum is useful only when its configuration matches the vehicle.
| Year / configuration | Towing Capacity | Manufacturer references |
|---|---|---|
| 2018 · 2.5L AWD CVT | 2700 lb | Reference 1 · 2026-09-05 |
| 2018 · 3.6L AWD CVT | 2700 lb | Reference 1 · 2026-09-05 |
Compare towing capacity across other models. Not published means the field has no compiled value for that configuration.
Subaru Outback Tire Size by year and engine
OE tire size means a tire size listed for an original equipment configuration. A model may have multiple wheel packages. Compare the full tire code and your door-jamb label, rather than treating every size listed for the model as interchangeable.
| Year / configuration | Tire Size | Manufacturer references |
|---|---|---|
| 2018 · 2.5L AWD CVT | 225/65R17 102H, 225/60R18 100H | Reference 1 · 2026-09-05 |
| 2018 · 3.6L AWD CVT | 225/60R18 100H | Reference 1 · 2026-09-05 |
Compare tire size across other models. Not published means the field has no compiled value for that configuration.
Subaru Outback Bolt Pattern by year and engine
A bolt-pattern code records the number of fasteners and pitch-circle diameter. It is only one part of wheel selection. A matching pattern does not establish the correct center bore, offset, wheel width or load rating.
| Year / configuration | Bolt Pattern | Manufacturer references |
|---|---|---|
| 2018 · 2.5L AWD CVT | Not published | Reference 1 · 2026-09-05 |
| 2018 · 3.6L AWD CVT | Not published | Reference 1 · 2026-09-05 |
Compare bolt pattern across other models. Not published means the field has no compiled value for that configuration.
Subaru Outback Transmission Fluid Capacity by year and engine
Identify the transmission as well as the engine. A conventional automatic, CVT, dual-clutch gearbox and manual transmission can require different fluids even within one model year.
| Year / configuration | Transmission Fluid Capacity | Manufacturer references |
|---|---|---|
| 2018 · 2.5L AWD CVT | 12.4 qt | Reference 1 · 2026-09-05 |
| 2018 · 3.6L AWD CVT | 13.4 qt | Reference 1 · 2026-09-05 |
Compare transmission fluid capacity across other models. Not published means the field has no compiled value for that configuration.
Subaru Outback Battery Group Size by year and engine
A battery group identifies a case-size category, but it does not establish all replacement requirements. Terminal arrangement, capacity, starting rating and battery technology may also be specified for the vehicle.
| Year / configuration | Battery Group Size | Manufacturer references |
|---|---|---|
| 2018 · 2.5L AWD CVT | 75D23R | Reference 1 · 2026-09-05 |
| 2018 · 3.6L AWD CVT | 75D23R | Reference 1 · 2026-09-05 |
Compare battery group size across other models. Not published means the field has no compiled value for that configuration.
Subaru Outback Wiper Blade Size by year and engine
Wiper sizes are recorded by position in inches. Driver and passenger blades may differ, and a rear blade is a separate fitment. Do not assume the two front blades use the same length.
| Year / configuration | Wiper Blade Size | Manufacturer references |
|---|---|---|
| 2018 · 2.5L AWD CVT | Not published | Reference 1 · 2026-09-05 |
| 2018 · 3.6L AWD CVT | Not published | Reference 1 · 2026-09-05 |
Compare wiper blade size across other models. Not published means the field has no compiled value for that configuration.
Subaru Outback Spark Plug Gap by year and engine
Spark plug gap is listed in inches for the specified engine. A turbocharged engine and a naturally aspirated engine in the same model may use different plugs or gaps.
| Year / configuration | Spark Plug Gap | Manufacturer references |
|---|---|---|
| 2018 · 2.5L AWD CVT | Not published | Reference 1 · 2026-09-05 |
| 2018 · 3.6L AWD CVT | Not published | Reference 1 · 2026-09-05 |
Compare spark plug gap across other models. Not published means the field has no compiled value for that configuration.
Subaru Outback Service Intervals by year and engine
Service intervals may be mileage-based, time-based or controlled by a maintenance monitor. Read the item description carefully: an initial coolant replacement can have a different schedule from later replacements.
| Year / configuration | Service Intervals | Manufacturer references |
|---|---|---|
| 2018 · 2.5L AWD CVT | Tire rotation: 7,500 mi / Not published mo | Reference 1 · 2026-09-05 |
| 2018 · 3.6L AWD CVT | Tire rotation: 7,500 mi / Not published mo | Reference 1 · 2026-09-05 |
Compare service intervals across other models. Not published means the field has no compiled value for that configuration.
Frequently asked questions
Does every Subaru Outback use the same oil capacity?
This reference separates 2 compiled engine configurations across 1 model years. Compare the oil-capacity table by year and engine; a model name alone does not identify the right fill quantity or oil specification.
Which Outback years have service specifications here?
Compiled service data is available for 2018. Other listed years have EPA fuel-economy and NHTSA records. We have not copied service values from one year into another.
Where are Subaru Outback recalls and fuel costs?
Open a model year in the table. The same page contains its MPG by engine, fuel-cost calculator, recall campaigns, safety ratings and any compiled service specifications.
