How to Break in an Automatic Transmission Car?
2 Answers
Automatic transmission car break-in methods are: 1. For the initial break-in period of 1 to 500 kilometers, the speed should not be too fast, generally below 70 to 80 kilometers per hour, with the engine speed not exceeding 2200 rpm; 2. For the mid-term break-in period of 500 to 1000 kilometers, the maximum speed can be appropriately increased, generally reaching 90 to 100 kilometers per hour, with the engine speed still below 2500 rpm; 3. For the final break-in period of 1000 to 1500 kilometers, the speed can be increased to below 120 kilometers per hour. Since break-in is a gradual process, it must be done step by step, with the engine speed not exceeding 3000 rpm. Appropriate speed increases will not affect the engine but can actually promote the break-in process.
When I first got this new automatic transmission car, I followed my friend's advice to focus on breaking it in. For the first 1,000 miles, extra caution is needed—avoid flooring the accelerator or speeding right off the bat, as that could cause excessive engine wear. I made sure to drive gently, gradually increasing speed during acceleration and keeping RPMs below 2,500, allowing internal components like pistons to settle in properly. City driving is ideal, with stop-and-go traffic helping achieve even break-in, but avoid prolonged idling in low-speed conditions. During the initial uses, check the oil level frequently, and consider an early first oil change at around 1,500 miles to clear out initial metal debris and prevent engine damage from accumulation. Avoid heavy loads or towing during break-in, and maintain proper tire pressure. Though modern cars are precision-built, careful break-in undeniably extends longevity and, in the long run, optimizes fuel efficiency and performance. Bonus tip: A weekly short warm-up drive helps condition the exhaust system for smoother overall operation.
