Should you check Subaru engine oil hot or cold?

Checking Subaru Engine Oil: Hot or Cold?
When it comes to checking the engine oil level in a Subaru, there is some debate about whether it should be done when the engine is hot or cold. Let’s take a look at the information available to determine the best approach.
Subaru’s Recommendation:
– According to a post on NASIOC, it is recommended to check the oil level when the engine is at normal operating temperature. After stopping the engine, it’s advised to let it sit for a couple of minutes for the oil to settle before checking it per the manual. This is because heat causes things to expand and take up more room, resulting in a hot engine having a higher fill-level than a cold one.
Community Insights:
– There are differing opinions within the Subaru community. Some users on the Subaru Forester Owners Forum and Reddit’s r/SubaruForester suggest checking the oil when the car is cold, particularly in the morning before running the engine. They argue that this allows all the oil to be in the sump, providing a more accurate reading .
– Others mention that the engine temperature may affect the oil level reading, with the oil’s temperature being more consistent if the car has been left overnight. They also note that measuring the oil level only 5 minutes after the engine was running may not provide an accurate result.
Conclusion:
Based on the available information, it seems that the general consensus leans towards checking the oil level when the engine is cold, particularly in the morning before running the engine. This allows the oil to settle in the oil pan, providing a more accurate reading. However, it’s important to note that Subaru’s official recommendation is to check the oil level when the engine is at normal operating temperature, after letting it sit for a couple of minutes to allow the oil to settle.
Ultimately, the decision may depend on individual preferences and practices, as well as the specific circumstances of the vehicle and its usage.
