- fit an Oil Level Gauge to your tank to alert you to an unusual drop in your oil level;
- install locks on tank filler caps;
- whilst you may not have a say on where your tank is positioned, it is wise to try planting bushes to prevent thieves getting to the tank easily or parking your vehicle so that access to the tank is restricted. Also if it is overlooked by a window or close to occupied property, most thieves will not take the risk of wanting to be seen;
- make note of any unfamiliar vehicles looking suspicious. It has been known that thieves are following Oil Delivery vehicles around different households knowing that they may potentially have a full tank.
Please don't approach anyone who appears to be behaving suspiciously - call the police.
