Our 20L Overland Edition Metal Jerry Cans come in both Petrol and Diesel options. Right next to the filler hole there is multi language text telling the user what fuel the can is for so the wrong contents are never added or used by mistake. This is very useful when travelling through countries that have attendants at the pumps that fill the fuel for you. We have personally experienced attendednts in the pass attempt to add the wrong fuel type to vehicles in the past.
The lid has an extra sliding pin so the lid can not be opened by mistake when in transit.
