With new CK-4 engine oils now on the market and in your trucks, you’re sure to be enjoying longer drain intervals and fewer oil changes. That’s because the advanced wear protection and viscosity control of this new class of oils can better handle higher underhood temperatures for longer periods of time than previous oil formulations.
Leaking radiators can do more than just reduce a truck’s fuel economy. They can also lead to low power, engine overheating and substandard emissions due to damaged hoses, head gaskets, thermostats, sensors, EGR coolers and diesel particulate filters.
