Whats everyone use over winter, i use the Screwfix stuff during summer but its not rated for winter use.

Something that can handle -10 should be plenty, not daft money either. Previously ive used Autoglym but that's £25+ for 5 litres that makes about 15 litres so £8+ per 5 litres, anything better priced.
 
I use Prestones Extreme Performance. Use it all year round actually just change the dilution. 1:9 works well for winter in my experience, 1:19 in autumn and spring. 1:29 for summer.
 
I've used Prestone the last few years, it's really good and it's sometimes on offer at Tesco for the larger bottles. Stick with the normal yellow one though, this summer I tried their luminous green one instead and it's rubbish, as it dries on the areas beyond the windscreen wipers it leaves lots of residue which I don't tend to get with the regular stuff.
 
I use Halfords concentrated, it's quite cheap and even better with trade card. I use it neat all year round. Never had any problems with it gunking up or anything. Smells lovely too!

Use concentrate rather than premix. You can then dilute it to suit the time of year.

Thats not what i asked. lol
I always use concentrate, Screwfix is concentrate as is the Autoglym stuff, just wondered if anything else worked out cheaper for at least -10.
 
Looks like Autoglym actually is pretty competitive, -45 neat, -14 at 1:2 works out at £1.78 per litre.
That Prestone looks decent as well.

Halfords is confusing me.

-10 concentrate £5
-10 ready mixed £4.50

Why would anyone buy the concentrate, if they wanted -10.

See above cheaper to use the ready mixed -10.

If it's the same sized bottle how is it cheaper to get ready mixed?

Your 5L of concentrate is going to make considerably more than just 5L unless you are using it neat, the 5L ready mixed is going to only ever be 5L unless you further dilute it... Or am i missing something?

Ditto the above, the berry one especially. Not sure why people buy pre mixed as who pays over the top for for water?

He said he was using it neat, so have other people in this thread. Works out cheaper to use the ready mixed.

Oh i see, I only saw your statement regarding pre-mixed being cheaper. I would think though that they do that because of the strength of it neat, hence not picking the cheaper diluted option... Who knows.

- The concentrate is £5 for 5l. But in order to work at -10c, it has to be used undiluted.
- The premix is £4.50 for 5l. It's advertised to work down to -10c as-is.

So presumably they are selling the exact same stuff in different bottles. So why bother with the concentrate when you can get the premix and use it in the same way (diluted as necessary) and save yourself 50p?

I will of course be contacting the UN to inform them of this dastardly scheme.

EDIT: I fail at reading threads. Updated post to make it more relevant.

Your mixing it wrong. You should make 50L out of a 5l tub of Autoglym screenwash. You only add 500mm to make 5l for normal winter use.

They even state themselves that 1:2 is for -14 so why are you saying that for -10 I can make 50l.
Even for -6 they say 1:4 so that's 25 liters from a 5 litre tub.
 
Ive never had to mix it that strong. I only ever put 500ml in and its never frozen, granted the temp here has only ever got down to about -7 or -8 though. It doesnt ever freeze when sprayed onto the screen and still defrosts some of the ice. Maybe I should have followed the instructions and used more.
 
either comma all season -26C , or eurocarpart triple qx -15C concentrates , both in the 70/80p / L @-10c

do a trial, to check they are miscible with what you currently use, or washout.
