Real South Texas Challenges, Real-World Solutions

Working in the Eagle Ford Shale means constant exposure to heat, dust, and vibration—all major stressors for diesel engines and hydraulic systems. Sand infiltration, hose bursts, and electrical shorts can shut down a job site fast. Lone Star Diesel Solutions technicians understand these conditions because we work in them every day. We bring practical solutions designed for oilfield realities, not shop theory.

Prevent Breakdowns Before They Happen

While emergency calls are our specialty, we also offer preventive maintenance programs for drilling and pumping equipment:

• Routine fluid and filter changes
• Hydraulic inspections and leak prevention
• Electrical testing for rig automation and sensors
• Drivetrain and clutch checks for service trucks
• Cooling system flushes and repairs

A consistent PM schedule minimizes costly shutdowns and extends equipment life.
