The 2016 Subaru Outback belongs to the 5th generation (2015-2019), built with 2.5L FB25 flat-four or 3.6L EZ36 flat-six, both with the Lineartronic CVT. It takes 0W-20 full synthetic. Oil changes run 6,000 miles or 6 months - notably shorter than most rivals. This is an early year of that generation, which usually means a handful of running changes were still being made.
A 2016 Subaru Outback is 10 years old in 2026, which at an average 12,000 miles a year puts it around 120,000 miles - high mileage. Near 120,000 miles you are past spark plugs, likely on a second set of brakes, and into suspension bushings, hoses and the water pump. Repairs start to outnumber scheduled services, and a written history is what tells you whether an item is due or already done. On that mileage estimate it should already have had spark plugs on most long-life applications at 120,000 miles, and the next milestone is 150,000 miles - transmission fluid again, plus hoses, mounts and suspension bushings - roughly 2.5 years away at average use.
The fault most worth knowing about on this generation is Oil consumption on some FB25 engines, which makes the short interval more important not less. Owners also report CVT chain and torque converter complaints on higher-mileage examples; and Battery drain complaints traced to parasitic draw on some builds. None of these are certainties on any individual vehicle - they are the patterns worth checking for when you buy or when a symptom appears.

| Every 6,000 mi / 6 months | Engine oil & filter change (0W-20 FB25; 5W-30 2.4T), Rotate tires, Inspect brakes and suspension, Inspect axle boots |
| Every 12,000 mi | Replace cabin air filter, Inspect brake pads and rotors, Check wheel alignment |
| Every 30,000 mi / 30 months | Replace engine air filter, Replace brake fluid (DOT 3), Inspect drive belt, Inspect steering and suspension |
| Every 60,000 mi | Replace spark plugs (FB25 and 2.4T iridium), Rear differential fluid change, CVT fluid drain & fill (recommended despite lifetime label), Inspect valve clearance (FB25) |
| Every 100,000 mi | Inspect Lineartronic CVT fluid and chain, Inspect timing chain and water pump, Inspect PCV valve |
| Every 137,500 mi / 11 years | Engine coolant flush (Subaru Super Coolant blue), Inspect entire cooling system |
The table above is indexed by service interval. This is the same schedule indexed by odometer reading, for when you know your mileage and want the list. If your odometer sits between these figures, work back to the last one you passed and catch up anything skipped.
| Odometer | Service due |
|---|---|
| 30,000 mi (48,000 km) | Engine oil & filter change (0W-20 FB25; 5W-30 2.4T), Rotate tires, Inspect brakes and suspension, Inspect axle boots, Replace engine air filter, Replace brake fluid (DOT 3), Inspect drive belt, Inspect steering and suspension. |
| 60,000 mi (97,000 km) | Engine oil & filter change (0W-20 FB25; 5W-30 2.4T), Rotate tires, Inspect brakes and suspension, Inspect axle boots, Replace cabin air filter, Inspect brake pads and rotors, Check wheel alignment, Replace engine air filter, Replace brake fluid (DOT 3), Inspect drive belt, Inspect steering and suspension, Replace spark plugs (FB25 and 2.4T iridium), Rear differential fluid change, CVT fluid drain & fill (recommended despite lifetime label), Inspect valve clearance (FB25). |
| 100,000 mi (161,000 km) | Inspect Lineartronic CVT fluid and chain, Inspect timing chain and water pump, Inspect PCV valve. The every-6,000 mi service runs on its own cycle - the nearest fall at 96,000 and 102,000 miles. |
| 120,000 mi (193,000 km) | Same as the 60,000 mi service. |
| 150,000 mi (241,000 km) | Same as the 30,000 mi service. |
| 200,000 mi (322,000 km) | Same as the 100,000 mi service. The every-6,000 mi service runs on its own cycle - the nearest fall at 198,000 and 204,000 miles. |
| Fastener | Torque | Size |

Maintenance keeps these away, but when the dash does light up these are the codes this vehicle throws most often - each with what it means and what the repair actually costs.
