Hot Shot's Secret 10W-30 Green Diamond Fleet Diesel Engine Oil from Lubrication Specialties is specially formulated for use in diesel powered vehicles that experience extreme temperatures, heavy loads, stop and go operations, or high airborne particulates. Green Diamond Fleet is ideal for all diesel-powered light, medium, and heavy duty trucks, industrial equipment, and stationary engines. As a severe duty diesel oil, it is a replacement for any CF-4, CJ-4, CI-4, and CI-4 Plus specification oil. The engine oil cleans, lubricates, and maintains engines and turbos for long-lasting protection, improved performance and fuel economy, and longer oil drain intervals, the company says.
