Oil Tank Protection...

[Craphouserat]

Does anybody have any oil tank protection they could recommend to me? I have looked at a couple of options via google, but wondered if anybody had any they liked/found useful?

Recently noticed a few chavs in their snotboxes doing a little tour of the little development we're in - our oil tank is a fair bit away from house and is the first tank in view when you drive down our road into the development.

Any recommendations appreciated.

Cheers.
