If you are trying to change the oil on your bike or car, the toughest part would be trying to get it all in without spilling it around. Without a funnel, this could be a daunting task.

In such cases where your funnel is missing or rendered useless due to any of the various reasons, how do you do it?

Take a screw driver and pour the viscous oil along the shaft of the screwdriver. The surface tension and the viscosity of the oil kick in and hold on to the shaft to allow you a spill-free work.

Also, since the screwdrivers are pointed, you can pretty much be extremely precise even if the hole is small enough to cause inconvenience.
