Break-In Procedures
Why Break-In Matters
A remanufactured engine is built with precision-machined surfaces, new piston rings, bearings, gaskets, seals, and updated components. The break-in process allows these components to properly seat and ensures long-term reliability. Failure to follow break-in procedures can cause:
Excessive oil consumption
Premature wear or scuffing
Overheating issues
Warranty denial for improper installation or neglect
Initial Start-Up (First 15–20 Minutes)
Prime the Oil System – Before starting, pre-fill the oil filter and crank the engine without spark/fuel to build oil pressure.
Check Fluids – Fill with manufacturer-recommended oil (typically conventional, not synthetic, for break-in) and coolant.
First Start – Start the engine and immediately bring RPM to 1,500–2,000 for the first 15–20 minutes. This allows proper camshaft and lifter break-in while ensuring good oil splash.
Monitor Gauges – Watch oil pressure, coolant temperature, and listen for abnormal noises.
Inspect for Leaks – Shut down and check for oil, coolant, or fuel leaks before proceeding.
First 500 Miles
Avoid High RPM & Heavy Loads – Keep RPM under 3,500 and avoid towing, hauling, or aggressive driving.
Vary Engine Speed – Do not use cruise control; vary speeds to help piston rings seat properly.
Short Trips vs. Long Trips – Mix city and highway driving, but avoid extended idling or long highway trips at constant RPM.
Oil Change at 500 Miles – Drain the break-in oil, replace filter, and refill with fresh conventional oil. This removes metal particles from the seating process.
500–1,000 Miles
Continue varying engine speed.
Light to moderate loads are acceptable, but no full-throttle accelerations.
At 1,000 miles, perform a second oil and filter change.
After 1,000 Miles
Switch to high-quality synthetic or synthetic-blend oil if desired.
Normal driving, towing, and hauling can resume.
Maintain regular oil changes every 3,000–5,000 miles (conventional) or 5,000–7,500 miles (synthetic), or as recommended by Fraser Engines.
Additional Tips for Long Engine Life
Always use premium filters (Fram Ultra, Wix, Mopar, Motorcraft, AC Delco, etc.).
Maintain proper cooling system function – replace thermostat, water pump, and radiator hoses during engine install.
Replace spark plugs, wires, and sensors if worn.
Use only manufacturer-approved coolant and oil specifications.
