Why does Subaru use synthetic oil?

Why Subaru Uses Synthetic Oil
Subaru uses synthetic oil for several reasons:
1. Engine Design and Performance:
– Synthetic oil, which consists of 80 percent synthetic base oil and 20 percent additives, is better formulated for low-friction, high-technology engine designs and for engines that face harsh driver demands.
– It is designed for improved fuel economy and increased power, and it provides increased protection against breakdown and superior lubrication for optimal fuel economy.
2. Turbocharged Engines:
– Turbocharged engines, such as those in the WRX and WRX STI, require synthetic oil due to running at higher temperatures, and 5W-30 synthetic oil is specifically formulated for these engines.
3. Environmental Impact:
– Synthetic oil is more pure than conventional oil and is designed to last much longer, which can reduce the overall environmental impact despite being made with certain chemicals that can be damaging to the environment.
4. Manufacturer Recommendations:
– Subaru requires the use of synthetic oil in newer models, such as the 2011 or newer Forester, 2012 or newer Impreza, and 2013 or newer Outback, Legacy, Crosstrek, Ascent, or BRZ .
In summary, Subaru uses synthetic oil to optimize engine performance, particularly in newer models and turbocharged engines, while also considering environmental impact and manufacturer recommendations.

When did Subaru start using synthetic oil?

2011
Starting in 2011 when Subaru changed from Rubber timing belts to timing chains in the 4 cylinder motors, the factory switched to full synthetic motor oils, 0w/20. The chain driven 6 cylinder motor, still uses 5/30 syntec blend.

Do Subarus need special oil changes?

No. Subaru Synthetic Motor Oil works with the same Subaru filters used with conventional motor oils.

Why is synthetic oil not good for older cars?

While synthetic oil generally protects better over a longer time, it flows more smoothly than conventional mineral oils – and for an older engine, this can mean a greater chance of grinding gears.

Is there a downside to synthetic oil?

Synthetics may be more prone to additives precipitation during cold storage conditions. This stratifies certain additives which can potentially lead to their complete separation from the oil. Multi-grade motor oils using synthetics may exhibit slightly less fuel economy at highway speeds compared to mineral oil.

Can I put conventional oil in my Subaru?

Subaru engines place varying demands on their motor oil. Naturally aspirated engines in the newest Forester, Impreza, Legacy, Outback, and BRZ models as well as turbocharged models require Subaru Synthetic Motor Oil (or its equivalent).

How often should synthetic oil be changed Subaru?

every 7,500 – 10,000 miles
Subaru suggests getting your Subaru oil & filter changed every 3,000-5,000 miles for conventional oil. Synthetic oil ordinarily should be changed every 7,500 – 10,000 miles. Keep in mind it’s best to check your owner’s manual and ask your dealer to find out the intervals that work best for your vehicle.

What brand of synthetic oil does Subaru use?

That’s why we created Genuine Subaru 5W-30 and 0W-20 Synthetic Motor Oils – two advanced synthetic formulations that outperform conventional motor oils in several ways: Provides superior protection against oil oxidation and breakdown. Ensures a cleaner running engine and longer engine life.
