Winterizing summer diesel

[Happy hillbily]

I have about 1200 litres of summer diesel in the tank, probably won't get through it till February (depending what the weather will throw at us) so have bought 5 litres of this to add 1.2 litres to my tank

Oh by the way, it's £21 cheaper to buy it through their shop on ebay than buying it direct
Now this is my tank

and I only have access to the front. So if I pour 1.2 litres of the anti wax into it, will it disperse throughout all of the fuel ?
Should I put the nozzle to run to circulate the fuel to help mix it, even though the pickup.pipe for the pump is almost directly below the filler. ?
Don't really want to be adding it separately to the different tractors as I use up the 1200 litres, I got caught out a few years ago, got stuck in a snowdrift with the 7610 and snowplough, and bottomed out the fuel tank on the snow, which was enough to wax up the fuel instantly, it was a right pita having to drag the dead tractor out and remove the fuel at the side of the road in the middle of a blizzard

Have used smith and Allen for years and there spot on, I’ve also found stuff to be cheaper through there eBay shop too, which is strange.

In your situation, similar to mine, I’d add it to the tank and recirculate for a while. Obviously the best time to add is on delivery day.
But for what it costs, and the aggravation it can save, I drop a dash in the tractor before I fill it up to be really sure.

Thanks for the nudge.
We stocked up in May so need to winterise and add preservative to see it through to next May.
I've a few packets of silica gel and half a pack of milk filter socks to make some diy water removers.

Thought red diesel was all now 'winter diesel' whatever time of year you got it? Certainly haven't had any issues for about 15yrs with waxing.

Back in the day ,,a bit of paraffin in the tractor tanks did the job ,,the old exposed metal tanks were renowned for going waxy
