In the shorter maintenance intervals of the past, drivers may never have lifted the hood to check fluids or picked up a tire gauge.
Today, with longer maintenance intervals, it’s time to dust off some old habits. While engineered to handle longer intervals and equipped with the fluids to do so, vehicles require occasional checks – including adding fluid(s) or air – to keep them running smoothly.
How much oil engines consume varies, based on manufacturing tolerances, wear, and usage. Usage includes driving patterns such as frequent engine braking (downshifting the transmission in order to decelerate the vehicle), engine operation at sustained high rpm (i.e., sustained highway driving or driving in hilly terrain), frequent acceleration and deceleration (i.e., stop-and-go freeway traffic), severe thermal conditions (extreme heat or cold), idling for extended periods of time (i.e., frequent and sustained remote engine-start operation), and new-engine break-in period (up to the first 3,000 miles).
All will result in increased engine oil consumption. However, the need to add oil should not be interpreted as a need for more frequent servicing. The qualities of Subaru synthetic oils are such that as long as the engine is not operated for extended periods of time with low oil, simply adding oil as necessary and following the scheduled maintenance intervals is an acceptable practice and will not negatively affect durability and longevity.
In the event of severe usage such as frequent trailer towing or carrying heavy loads, then shorter maintenance intervals are highly recommended.
Low-oil level warning light: If this light illuminates when you’re driving:
After adding oil, the warning light should go out after restarting the engine.
Low-oil pressure warning light: If it illuminates when you’re driving:
- Stop as quickly as possible in a safe place
- Turn off the engine
- Check engine oil level
- If the oil level is low, add oil immediately
- If the engine oil is at the proper level but the light remains illuminated, contact your nearest Subaru retailer immediately
