[QUOTE="CATDiezel, post: 1393019, member: 4387"] Hot fuel has a pretty nasty affect on lubricity and high pressure components. The United States government did a test on the 6.7L fuel system proving the points on lubricity and the wear on injectors and pumps. Being they use the 6.7L in some of their militany vehicles or plan on doing so. Caterpillar swears up and down the loss of lubricity of the fuel is greatly lowered past 140*F. That's why they start putting the engine into a pretty hefty engine derate above that temperature. [/QUOTE]
