I encountered a concerning situation with my Suburu today when an “At Oil Temp” warning light flashed on the dashboard. I’m unsure what it indicates and why the oil temperature would rise unusually. Is there a typical temperature range for engine oil, and at what point should I be concerned?
The “At Oil Temp” light you’ve noticed is indeed a signal to pay attention to, as it pertains to your vehicle’s well-being. Under normal operating conditions, engine oil temperatures should ideally be between 220-250 degrees Fahrenheit. When it exceeds 275 degrees, the oil begins to break down, which can lead to serious engine issues.
However, it’s crucial to note that the “At Oil Temp” warning specifically relates to your transmission oil, not the engine oil. The transmission oil is optimal at or below 200 degrees Fahrenheit. If this light is on, it’s a sign that your transmission oil may be overheating, which is more common than engine oil overheating.
If your vehicle is running hotter than usual or you detect a burning smell, it’s possible that your engine oil is also overheated. This could be due to an overworked or malfunctioning coolant system. On the other hand, if the engine is operating within the normal range, your engine oil typically won’t surpass 220 degrees Fahrenheit.
To ensure your vehicle’s health and safety, we recommend having a professional mechanic inspect your coolant system and overall engine health. This will help diagnose any issues and prevent potential damage.
Stay safe on the roads, and remember, your vehicle’s warnings are there to help you maintain its longevity and performance.
