I encountered the old problem of diesel waxing on a loan 300 defender something I havent had in years , I added petrol (as you do ) at about 10-1 which should be about right. I was told that it was ok on older vehicles but not on newer ones ( common rail injection ) question is ,if you cant use petrol what else can go in to prevent waxing.
 
Its probably on summer diesel. The oil companies automatically add the appropriate anti-waxing stuff to DERV at various times of the year etc so its never normally a problem down to about -20 deg C. I don't know what the actual stuff is they add, but you can get it if needs be.

Are you in an area around or below -20? Could the fuel be old?

Diesel should last years and years, it's not like petrol which will go bad after standing for a while.

I think our derv in the UK is only protected against waxing down to -15 or thereabouts.

Its not about going off/stale, its because summer diesel doesn't have as much anti-waxing additive. If it was on last year's winter diesel.....etc
