It’s easy to forget the importance of regular vehicle maintenance, but changing the oil is one of the simplest, most essential ways to enhance your Subaru vehicle’s performance and increase its lifespan.
While the general recommendation is that you should change your oil every 3,000 miles, newer vehicles can keep the oil churning for 5,000 to 7,000 miles.

The oil I was using for my car was only rated to 5 quarts, but I have since gotten a few more and have been using them on all my engines since. I did a little research and came up with 2 different types of oil, the type I was using had higher viscosity and I would expect a higher performance from the engine, I decided to try a lower viscosity one.
My new oil changed the car’s idle speed from 20,000 rpm to 25,000 rpm. I have since tested and it was not because of the lower viscosity oil, and in fact, it has not changed any idle speed on my car. The lower viscosity oil did not cause any changes in any other aspects of my car, including the engine’s oil pressure. The one thing I do know is that it is a much better oil than the previous one, and it has not changed the idle speed on my car.
Hi, Val.
In case of using the recommended oil viscosity range (above in article) the car’s idle shouldn’t change. Having this problem, I would say it’s not because of oil.
