just a quick heads up and wanted to know if you had problems in the past with this.
The rear flap you open to top up the oil is unlocked and free for anyone to open an pour whatever they wanted in your engine.
I never thought about this before but I started being wary of not showing my neighbours that flap is unlocked. I have no enemies, but you never know.
Of course not many people know about that flap, but is it visible that it's not part of the rest of the body.
Another option would be to fit a padlock, but it would be ugly as f and also visible and that's when you attract attention.
Right...I leave it with you now
