Breaking in Your New Engine

After installation by a qualified professional mechanic, the initial break-in period is a crucial time in maximizing your warranty and the longevity of your new engine.

After initial installation by a qualified professional mechanic, and before starting your new engine for the first time, add three quarts of high-quality grade SAE 30 motor oil with a zinc anti-wear additive.

During the initial break-in period, avoid excessive RPM at all times, and follow this schedule to break in your new engine.

The valve lash clearance should be adjusted to 0.006”on both the intake and exhaust valves.

• At 300 miles, adjust the valves.

• At 500 miles, change the oil and adjust the valves again.

• At 3,000 miles, change the oil and adjust the valves again. This is your first regular maintenance interval. Switch to a high-quality grade SAE 30 detergent motor oil.

Every time the valves are adjusted the engine must be cold, preferably after cooling overnight.

If you plan to drive the vehicle year-round in cold climates, change to multi-grade SAE 10W-40 for the winter months.

From here on, we recommend changing the oil and checking the valve adjustment every 3,000 miles and adjusting the valves every 6,000 miles.
