Yep, but JetA1 has a lower calorific value than diesel by a factor of about 15% in real use (ie less range from tank). It is a dry fuel though, so about 4l of cheapest mineral two stroke oil per 200l of JetA1 for lubrication of the injector pump. I have run an 80-90% JetA1 mix before, but usually use about 20% in tank. Common rail diesels don't seem to like it, and may not be good for them, but my 1KZTE has no problem with it. You can also pretty much guarantee it is unadulterated by any other cr@p that some vendors bulk up their diesel with.
