Oil and Water
Yes, this is a bit of a girls question but I'm hoping someone can help. I try to check the oil and water in my car regularly but am confused about whether you should check when the engine is cold, or (as my step dad says) start and run the car for a bit (something to do with the sump) first so that the engine is warm. Is it different for oil and water? I'm guessing checking the water when it's hot would be a bad thing....
Thanks for your help.

As for the water, you were quite right to say it would be a bad thing when hot. Do not attempt to remove water filling cap when engine is hot. These days most cars have a reservoir that is see through, and a mark on the side showing where the water level should be.
