Examining the surfaces of the parts of the new engine under a microscope, small depressions and bumps with sharp tops are noticeable. Correctly run-in in a gentle mode, the motor will smooth out irregularities and "thank" its owner with a long and flawless work.
Necessary
a car with a new or overhauled engine
Instructions
Step 1
Do not overheat the new motor. Minimize engine idling. If your car has a manual transmission, avoid driving in fifth gear and engine braking. Remember that owners of cars with automatic transmission are not recommended to drive at the fourth and sixth speeds, as well as braking in manual mode.
Step 2
Start moving smoothly, preheating the engine for five minutes. Maintain engine rpm in the 1600-2100 range and do not shift higher than third gear in the manual transmission.
Step 3
When warming up the car in motion, forcibly set the mode, which does not provide for switching further than the second with a four-speed and third gear with a six-speed automatic transmission.
Step 4
Remember that long-term operation in urban traffic conditions is contraindicated for a new engine. Frequent abrupt starts, braking and idling during prolonged parking are harmful to any car. If you get stuck in a traffic jam, increase the engine speed to 1000 - 1200. The increased oil pressure will improve the lubrication of the engine parts of your machine.
Step 5
When purchasing a new car or installing an engine after a major overhaul, take the time to drive on a clean, high-quality highway. An ideal option for running a car is a two hundred kilometers long one way route. When driving on the highway, do not shift higher than fourth gear. Do not exceed three thousand revolutions per minute the rotation of the engine of your car and do not accelerate it more than 80 km / h.
Step 6
Check the oil and technical fluid levels in your vehicle before each ride. Monitor tire pressure. Do not experiment with a dry engine while checking the manufacturer's specified acceleration and maximum speed of the machine.
