A decent oil pan but would benefit from being larger
This oil pan works decently but would be much better if it were slightly larger. At the size it is it is easy to miss the pan and make a mess. The pan holds enough oil for a bike or lawnmower but not enough for a car or truck. The plugs screw on well and don’t leak from my use. But the pan has inner lips that hold oil and make it hard to clean, would be much better if it were a smooth surface. The pan is made of thick plastic though and is well built overall, it just could be designed better.

Too small to avoid spilling/splashing!
Returning it as this was way smaller than expected!
