The reason for this is that when the engine is hot, the oil is under pressure and can come out very quickly when you remove the dipstick. This can cause serious burns if you’re not careful.

Why Check Engine Oil When Warm
If you’re like most car owners, you probably check your engine oil level when the engine is cold. But did you know that it’s actually better to check your oil level when the engine is warm? Here’s why:
When the engine is cold, the oil is thicker and doesn’t flow as easily. This can make it difficult to get an accurate reading on the dipstick.
Warm oil flows more easily and will give you a more accurate reading.
Plus, if there is any water in the oil, it will evaporate at higher temperatures, so checking when the engine is warm will help you spot any potential problems.
When Should You Check Engine Oil Level
Assuming you have an oil dipstick in your car:
Check your engine oil at least once a month, and more often if you drive frequently or regularly haul heavy loads. Checking your oil is easy and only takes a few minutes.
Here’s how:
Pull out the dipstick (usually it has a yellow or orange handle) and wipe it off with a clean rag. Reinsert the dipstick all the way back into the tube, then pull it out again to check the level.
The oil should reach somewhere between the “low” and “full” marks on the dipstick. If it doesn’t, add enough oil to bring it up to those levels.
Do You Check Oil With Car on Or off
If you’re wondering whether to check your car’s oil level with the engine on or off, there is no definitive answer. However, checking the oil while the engine is cold will give you the most accurate reading. If you check it when the engine is hot, the oil may appear higher than it actually is due to expansion.
Check Oil Hot Or Cold Reddit

If you check your oil when it’s cold, you risk getting an inaccurate reading. That’s because when oil is cold, it’s more viscous and will appear fuller than it actually is. However, checking your oil when it’s hot has its own set of risks.
Hot oil can cause burns, so be sure to use caution if you go this route.
The bottom line is that the best time to check your oil level is when the engine is warm but not hot. This way you can get a more accurate reading without putting yourself in danger.
Conclusion
It’s important to check your oil level regularly, and most people will tell you that it’s best to do so when the engine is hot. However, there are some benefits to checking it when the engine is cold as well. Here are a few things to keep in mind:
1. Hot engines burn more oil. If you’re low on oil, checking when the engine is cold will give you a better idea of how much you need to add.
2. Cold engines have thicker oil.
This means that it’s easier to see if there’s any debris in the oil when it’s cold. If there is debris, it’s likely that something is wrong with your engine and you should take it to a mechanic.
3. Cold weather can cause condensation in your engine, which can mix with the oil and make it less effective.
Checking the oil level when the engine is cold can help you avoid this problem.
