I wouldn't try it on 100% mate, but there's places that do a 65 / 35 mix, 65 being normal diesel.
That should be fine in it.
The 100% we've just had to drain out of a Focus 1.8TDDI after it started runnin' like a dog and got worse and worse.
Drained the tank, put BP Ultimate in it (won't have 100% drained tank you see) and it's fine now.
