第四代斯巴鲁欧tback Maintenance and Cost
In naturally aspirated and unstressed form, as used in the 2010-2012 Subaru Outback, the EJ25 engine is a pretty reliable workhorse, provided it is serviced punctually and thoroughly. The 3.6-liter EZ36D and FB25B engines are even less demanding of unscheduled attention, but they all depend on frequent oil changes to keep working at their best. We recommend oil and filter changes every 5,000 miles to keep their sumps and oil passage clear of potential debris buildup.
业主的车辆配备的林eartronic CVTs would be well-advised to replace their transmission fluid and filter every 30,000 miles to avoid 2010-2014 Subaru CVT problems, while the five-speed automatic in 3.6R variants needs fresh oil and a filter change every 60,000 miles at the latest. The engine's air filter should be good for 30,000 miles, but the cabin's air filter will need replacement every 15,000 miles. If your vehicle operates in dusty or other harsh conditions, you should shorten the filter-replacement interval, however.
Spark plugs should be replaced at 60,000 miles (Subaru recommends 70,000 miles), but it's important to stick to the manufacturer's spark-plug specifications when the time comes for replacement, as incorrect spark plugs in any of these engines could cause a noticeable drop in performance and increase the fuel consumption.
Finally, the cam timing belt, tensioners and belt-driven coolant pump on EJ253-engined Outbacks need to be replaced every 60,000 miles to remain on the safe side, even if some official literature states a replacement interval of 90,000 miles for these items.
