For the Philippines it is pretty much good for any diesel, except BMW, or Mercedes and the newer rovers (high end stuff) with extreamly high rail pressures and super advanced piezoelectric injectors. (Example these cars are making 2000bar/29000psi of fuel pressure vs a 3.0 D4D which is only 1350bar/19580psi so this could cause a problem if your thicking things up)
Works fine on D4D engines like the Fortuner with no issues, Would probably solve a bunch of issues with the 2.5 D4D as well.
No real testing shows it causes any issues to any vehicle, the 2007 and up thing is a recomendation ie the word (may cause harm). And since the CRDI sold there are not the super high tech ones I would not hesitate on using it.
But if you got a non common rail diesel (Any) you should not hesitate to use it. Once you start you won't stop putting it in
