That's the regular summer formula, the winter ones were reduced to clear a while back.
I hope they are not putting the rain-x type stuff in this . The last Prestone screen wash i bought i had to throw away and it ruined the windscreen for weeks because of that ridiculous additive in it that causes lots of smearing and cold morning fogging.
their stock of winter (yellow) screen wash is half price to make way for the green stuff. loads of it in the entrance area at Tesco in Swansea yesterday.
Nice spot, found it not as good as the winter/all season but still a good deal!
