Of course, its reliable - the diesel engines. My mistake, my english is not good. I wanted to say not much more reliable than petrol, maybe not at all. There was a lot of army defenders in my Country during the war in 1990s. We have also very old Lrs and they stil use their diesel engines from 60s, no problems. But, there are petrols from same period and it also still goes. Mine is 2,5 and it works realy nice without problems. I like diesels very much. But this is something special. More power? I dont need it. What for? Do You use it?
