I see photos of ISIS, Iraqi Army, and regular civilians in Irag and Syria and most appear to be driving around in Toyota PU trucks. Now these are almost 3d world countries, the weather is hot and the roads are dusty. You have to wonder what kind of maintenance these trucks get and how frequently. It must be severe service +. Either Toyota is making some really tough engines or they are getting fed a diet of super engine oils. Any one know what kind of oil the get fed, preferred brand or weight, and how often?
