DPF isnt the right answer
	
	
		DPF is a bad answer, so is EGR, which is what it is paired with. Adblue is the way to go, always has been, like all things that the euros do, Liebherr crane engines oil drain at 500 hrs, oil looks new. they run hotter, cleaner, perfect. Volvo trucks have had adblue for years. Cat dont even sell a truck engine anymore. More power, less fuel.
All cars have their issues for sure, My LR4 has been great touch wood, Sure I have had some bad Toyota experiences, i had the first of the 4.5L V8 diesels in a work ute 3 engines. But the reality is nothing out last Hilux especially in bad conditions, we have them here on a north african mine site and they have 300'000ks, sure they are rooted, but the mechanics here cause most of the issues not the car itself. Generally a cheap fix if you buy one too, because of market share eveyone wants to support them and get a peice of the pie.
Ive seen a heap of those DPF hilux's blowing plumes of smoke, does need to be fixed. a place i worked even had one go bang.
as for Toyota petrol's, amazing vehicles, never ever give problems, my plumber had a hiace 2.7 with 220,000 k's and i did its second service at 220,000ks, he still has it, still says it doesnt need a service, i only did the job becuase his asked me to.
