Pre-Road Trip Vehicle Inspection & Maintenance Checklist
Continuous highway driving places sustained stress on internal engine bearings, tires, and electrical systems. Inspect these four critical vehicle components before departing to avoid mechanical breakdowns:
🛢️ Engine Oil & Filter Capacity
Verify crankcase oil capacity and viscosity grade (0W-20, 5W-30). Running low oil under continuous high RPMs causes rapid heat buildup and premature bearing wear.
🔋 12V Battery Group Size & CCA
Confirm BCI battery group sizes, terminal health, and Cold Cranking Amps (CCA) to prevent starting failures at remote rest stops.
⚙️ Wheel Lug Nut Torque Specs
Torque all wheel lug nuts to exact factory Foot-Pounds and Newton-Meters with a calibrated torque wrench to prevent dangerous wheel wobble.
