To ensure that your 2022 Subaru Forester, Outback, Crossstroke, Ascent, or other new model engine will be reliable for years to come, be vigilant about oil changes. Oil is the lifeblood of your engine and the lowest maintenance cost you can do to keep your 4WD vehicle running well. The three primary functions of your engine oil are cushioning (lubrication), cleaning (removing contaminants), and keeping your Subaru Boxer engine cool.
What oil should i use?
If your Subaru is a 2011 or newer, 2012 or newer Impreza, 2013 or newer Outback, Legacy, Crosstrek, Ascent or BRZ, Subaru says to use synthetic oil. Subaru recommends the use of Subaru Genuine Oil and 0W-20 viscosity in these engines. It is designed to improve fuel economy and increase power. The 5W-30 is designed for the turbocharged engine in the WRX and WRX STI, which operates at higher temperatures. It has increased protection against oil degradation and superior lubrication for optimum fuel economy.
Will using synthetic oil increase fuel mileage?
Many oil manufacturers claim that using synthetic oil will improve fuel mileage, but is this true? A recent study from the fleet government says they did not see an increase in fuel mileage using synthetic oil in their test.
Will using synthetic oil extend the life of the oil?
The same study said that switching from a mineral blend motor oil to a full synthetic oil could extend the life of the oil, “a claim that independent scientists can confirm in laboratory tests.”
How often should I change the engine oil?
Subaru recommends changing the oil for the first time in six months and no more than 6000 miles. However, it’s a good idea to change it at 3000-4000 miles because the engine will have just arrived during the initial breakout period (3,000 miles), especially since the new engine will see a little more wear.
Regular maintenance is key
Driving habits and conditions will affect how often you should change the oil. After your first oil change, Subaru says you should change it every 6,000 miles with synthetic oil. But this is if you are driving in “normal” conditions. Most engines operate in harsh conditions.
What are the extreme driving conditions?
Extreme conditions include:
Frequent engine braking (lowering the transmission to slow the car).
Engine running at high rpm (continuous highway driving or hilly terrain).
Excessive acceleration and deceleration (highway traffic stops and starts).
Extreme thermal conditions (extreme heat or cold).
prolonged idling (repeated and continuous start-up of the remote engine).
Extreme conditions require frequent oil changes
If you drive in harsh conditions, you will need to change the oil frequently. We recommend changing it every 4000-5000 if you are using synthetic oil, especially if you have more than one of the conditions listed above.
Why does my Subaru engine use oil between changes?
Since many manufacturers are now using these zero-weight “skinny” synthetic oils to squeeze in small improvements in fuel economy, you may experience some oil consumption between oil changes. It’s a good idea to check your car’s oil level often, about once a month, if you drive 12,000 miles a year.
Check the oil level often
You may experience some oil consumption in more severe conditions and may need to “top” the oil between oil changes. Don’t let your Subaru engine drop below the bottom point on your dipstick, or else your engine could overheat, and you’ll experience premature engine wear or engine failure.
The best way to make sure that your 2022 Subaru Forester, Outback, Crossstroke, Ascent, or other model engine will be reliable for years to come is to remain vigilant about oil changes. It will also help you get the best fuel efficiency.
