No, it’s not bad. Slightly overfilling the oil by one quart should not cause any problems and won’t hurt anything.
The dipstick shows it’s just above the full mark, which is acceptable and won’t lead to significant issues. However, it can be bad for the catalytic converter.
Let’s see why you should restrain yourself from using extra oil in the engine. The knowledge will come in very handy for you in the future.

5 Quarts and 4 quarts: Diffrences
| Aspect | 5 Quarts of Oil | 4 Quarts of Oil |
| Oil Capacity | Greater amount of oil added | Lesser amount of oil added |
| Engine Performance | Usually do not impact performance | Won’t significantly impact performance |
| Manufacturer | Some cars designed to accommodate 5 | Most cars designed for 4 quarts |
| Recommendations | quarts without issues | without issues |
| Potential Impact on Engine | Excessive overfilling could cause issues; need to check oil level correctly | Result in a lower oil level than recommended, leading to potential engine damage if ignored |
| Necessity of Draining Excess Oil | If significantly overfilled, draining some oil may be necessary | If significantly underfilled, topping up with an additional quart may be required |
Factors To Consider Before Putting 5 Quarts Of Oil Instead Of 4
Adding too much oil can have adverse effects on the engine and may lead to potential issues. Here are the key factors to take into account before putting 5 quarts of oil instead of 4 quarts:
Engine Capacity
Check the manufacturer’s recommendations for the engine’s oil capacity. The engine is designed to operate with a specific oil volume, and exceeding this capacity could cause problems like foaming, increased pressure, and oil leaks.
Oil Level Check
Ensure that the current oil level is below the safe limit and requires additional oil. Overfilling the oil can lead to excessive pressure within the crankcase, leading to oil leaks and other complications.
Oil Viscosity
Consider the type and viscosity of the oil you are using. Different engines require specific types of oil, and the incorrect viscosity could negatively impact engine performance.
Vehicle Type
The type of vehicle matters too. Different engines have varying oil capacities, and some may be more sensitive to overfilling than others.
Driving Conditions
If the vehicle is subject to heavy loads, towing, or extreme driving conditions, you might consider a slightly higher oil level, but it should still stay within the manufacturer’s recommended range.
Temperature Considerations
Engine oil expands as it heats up. In hot conditions, the oil may expand beyond the safe limit if you’ve already filled it to the maximum.
Potential Damage
Overfilling the oil can cause the crankshaft to come into contact with the oil, creating air bubbles, which reduces its lubricating properties. This can lead to increased friction, excess heat, and premature engine wear.
Fuel Efficiency
Excessive oil levels can lead to increased resistance and reduce fuel efficiency.
Safety
An overfilled engine can cause oil to spill onto hot engine components, leading to smoke, burning smells, and even a risk of fire.
Warranty
Check the vehicle’s warranty terms. Some warranties may be voided if the engine damage is a result of improper maintenance, including overfilling the oil.
