Here's why:
* Overfilling: Adding too much oil can cause several problems, including:
* Increased pressure: This can damage seals and gaskets, leading to leaks.
* Foaming: Excess oil can get whipped into a foam by the crankshaft, reducing its lubricating properties.
* Engine damage: Foaming and increased pressure can lead to problems with the oil pump and other engine components.
* Misinterpretation: Adding oil when your engine doesn't need it can mask other underlying problems, such as a leak or oil consumption.
What to do instead:
1. Check your owner's manual: It will specify the correct oil capacity for your engine.
2. Use a dipstick: Regularly check your oil level using the dipstick.
3. Don't overfill: Only add oil if the dipstick shows you're below the "full" mark.
4. If you suspect a leak: Address the issue promptly. Don't just keep adding oil.
Important Note: Always consult your vehicle's owner's manual for specific instructions regarding oil levels and maintenance.
