How does google view...

[JamesT]

I have two urls that are almost the same for example:

www.mysite.co.uk/motoring/car_fuel

www.mysite.co.uk/motoring/car-fuel

both pages are very different, but on the same topic.

How does google view the use of _ and - in urls? Will it see my urls as different?

Please advise if you know the answer. Thank You.

Dashes are Google's preferred word separators. (I have heard that underscores are considered to be word joiners, so in that case your first one would be carfuel rather than car fuel but I am not sure whether that is correct.)

In any case, the two would tend to look the same to your human readers and could cause some confusion there, so if you have the option to change one, I would.
