The Best Oil For Your New Subaru Engine And How To Get The Longest Life

Source: Torque News

The most critical part of ensuring your new Subaru Outback, Forester, Crosstrek, Ascent, Impreza, Legacy, WRX /STI or BRZ engine will be reliable for years to come is to remain vigilant on the oil changes. Oil is the lifeblood of your engine and the least expensive maintenance you can do to keep your Subaru running well. The three Cs and main functions of your engine’s oil are to Cushion (lubricates), Clean (removes contaminants), and to keep your Subaru Boxer engine Cool.

How often should I change my engine oil?

Subaru recommends getting your first oil change at 6 months and not more than 9,5000 kilometres. However, it’s a good idea to change it at 5,000-6,500 kilometres since the engine will have just come through the initial break-in period (5,000 kilometres). Especially since a new engine will experience slightly more wear during this time.

Subaru oil change schedule and how often you should change it

Regular maintenance is the key

After your first oil change, Subaru says you should change it every 9,500 kilometres using synthetic oil. But this is if you drive in “normal” conditions. Driving habits and conditions will affect how often you should change your oil.

What are the extreme driving conditions?

Driving patterns such as frequent engine braking (downshifting the transmission in order to decelerate the vehicle), engine operation at sustained high rpm (sustained highway driving or driving in mountainous terrain), frequent acceleration and deceleration (stop-and-go highway traffic) Severe thermal conditions (extreme heat or cold), and idling for extended periods of time (frequent and sustained remote engine-start operation).

change your oil more often in extreme conditions

Extreme conditions require more frequent oil changes

If your vehicle has any of these extreme driving conditions you will need to change your oil more frequently. We would recommend changing it every 6,500-8,000 especially if you have more than one of the extremes above.

What oil should I use?

If your Subaru is a 2011 or newer Forester, a 2012 or newer Impreza, or a 2013 or newer Outback, Legacy, Crosstrek, Ascent, or BRZ, it is required to use synthetic oil. Subaru recommends using Genuine Subaru oil and 0W-20 viscosity in all of these engines, designed for improved fuel economy and increased power. 5W-30 is formulated for the turbocharged engine in the WRX and WRX STI, which runs at higher temperatures. It has increased protection against breakdown, and superior lubrication for optimal fuel economy.

Check the oil level often

If your driving patterns involve any extreme conditions, you will likely experience some oil consumption and need to “top off” your oil between oil changes. Don’t let your Subaru engine go below the bottom dot on your dipstick, or your engine can overheat and you will experience premature engine wear or engine failure.

The best way to ensure your new Subaru Outback, Forester, Crosstrek, Ascent, Impreza, WRX /STI or BRZ engine will be reliable for years to come is to remain vigilant on the oil changes.
