There's a catch in it somewhere!
Apparently the most frequently Googled motoring question is, how do I open the bonnet of my car?
The second one is, how do I know how much oil my car needs? Well, that should be in the manual, but the manual might not be available if the car has been bought second hand. Providing the owner didn't have to ask Google how to open the bonnet, hopefully they would be able to identify the dipstick and check the oil level (when it's cold of course).
