Jet A1 in A Diesel

[Zad]

I imagine if its diluted in diesel at a fairly low ratio, say, 1:10 then the engine probably won't know any difference. Would I try it myself? Ehh... hmm. Not this week. Failing that, fit an Eberspaecher cab heater to your garage / shed / man cave for some winter heat to keep your P&J / porn stash dry
