The tank took around 9 litre to overflow at 11035 miles. Plus 250ml of Wynn's Crystal Clear and Protect, treatment that stops AdBlue crystallising. The previous fill was at 8899 and so we have covered 2136 miles. I had expected a little more than 230 miles per litre! By the time we get back from Sissinghurst at the weekend we'll have covered another 2000 miles or so since the last fill. I have quite a lot of the last batch in the garage and I might treat that with some of the Wynn's before use in the van. I had hoped that the next time we will need to top up will be when we are in Spain. I don't think we can wait anther 1000 miles and before Spain we have another few trip here in the UK. It was very cheap, as was diesel, at the station on the way from the A7/N340 towards Peñíscola. I topped up "old" Molly there last year.
