There are a few potential causes for a car to smell like burning oil. Some possible reasons include:
- An oil leak: If the car has an oil leak, it can cause the oil to drip onto hot surfaces, such as the exhaust manifold or catalytic converter, and produce a burning oil smell.
- Low oil level: If the oil level in the car is low, it can cause the engine to run hotter than normal and produce a burning oil smell.
- Worn engine parts: If the car has worn engine parts, such as worn valve guides or seals, it can cause the oil to leak and produce a burning oil smell.
- Overheating: If the car is overheating, it can cause the oil to burn and produce a burning oil smell.

If your car is smelling like burning oil and it started right after an oil change, it could be caused by a few different issues. Some potential causes include:
- Incorrect oil type or viscosity: If the wrong type of oil or oil with the wrong viscosity was used during the oil change, it can cause the oil to break down or burn more quickly than normal, leading to a burning oil smell.
- Improper oil level: If too much or too little oil was added during the oil change, it can cause the engine to run hotter than normal and produce a burning oil smell.
- A malfunctioning oil filter: If the oil filter is not functioning properly, it can cause the oil to become contaminated or bypass the filter altogether, leading to a burning oil smell.
- Other issues with the oil change: If the oil change was not performed correctly, it can cause the car to develop issues that can lead to a burning oil smell.
