The method increments the car's speed by 4 miles per hour and decreases the fuel level by 0.05. The car cannot accelerate if the engine is not on. Also, don t accelerate if the car does not have enough fuel (0.05 amount) to do that. If the current speed is the maximum, then acceleration won t increase the speed but will burn fuel. It returns true if it accelerates, increases the car speed by some amount, the car and false, otherwise.

Here is a possible implementation of the method in Python:
```python
def accelerate(car):
if not car.engine_on or car.fuel < 0.05:
return False
if car.speed < car.max_speed:
car.speed += 4
car.fuel -= 0.05
return True
else:
car.fuel -= 0.05
return False
```
This function takes a `car` object as input, which should have at least the following attributes: `engine_on`, `fuel`, `speed`, and `max_speed`. It first checks if the engine is on and if there is enough fuel to accelerate, and returns `False` if either condition is not met. If the current speed is lower than the maximum speed, it increases the speed by 4 and decreases the fuel level by 0.05, and returns `True`. If the current speed is already at the maximum, it just burns fuel and returns `False`.
