My 2012 plus 4 is reputed to have a 45 litre tank... thats what the manual says. On a long trip recently I let it drop to just under a quarter on the gauge.... was getting quite anxious based on the mikes covered. On filling her up I got 42 litres in. Hmm.

I'm half tempted to run it until dry but I really don't want to stir up all the cak in the bottom of the tank and get it into the filter pump and injectors
