Engine revision When finished, the most visible part of the work is left behind; But the period that really determines the life of the engine begins now. A certain distance is needed for the newly machined cylinder surfaces and the rings to "get used" to each other. to this period running in It is called and misuse can ruin even the best quality workmanship.
The first 500 km: the most sensitive period
- Do not go at constant speed. Driving at the same speed for a long time causes the cylinder surface to wear at a single point. Change speed and load gradually.
- Do not force the engine. Full throttle, high revs and sudden starts are prohibited during this period. It is safest to keep the rpm in the middle of the manufacturer's specified range.
- Do not run it idle for a long time. It is more important for the engine to reach operating temperature; Drive normally instead of starting and stopping for a short time.
- Check the oil level every 300–500 km. In the first period after revision, oil consumption may be slightly higher than normal; This is part of the seating process of the rings.
500–1,000 Km: gradual increase
During this period, you can gradually expand the rev range. Again, no full throttle; but allowing the engine to compress while braking helps the rings sit on the surface. Mixed urban + extra-urban driving is better than single-type driving.
Why is the first oil change important?
Fine metal particles remaining from machine operations and auxiliary materials used during assembly mix with the oil in the first kilometers. So after revision First oil and filter change around 1,000–1,500 km We recommend doing this. This means the engine runs on clean oil; The next maintenance interval is also planned from this date.
Which symptoms are normal during break-in and which are not?
| Symptom | Evaluation |
|---|---|
| Light oil consumption | It is considered normal in the first period and is followed |
| Short-term water vapor from exhaust | It is normal |
| Continuous blue smoke | It's not normal; fat burning is researched |
| Metallic sound, bed knocking | urgent; vehicle does not start |
| temperature rise | urgent; cooling system is checked |
In this table, the top two rows are trackable, while the bottom three rows are not. We check the sound, oil pressure and temperature behavior of the engine after the first start-up before delivery; The best thing for you to do is to report any early symptoms to us over the phone.
Warranty and tracking
For engine work we provide a 5,000 km warranty We apply. In order for the warranty to function properly, break-in rules must be followed and the first oil change must be made on time. A doubt that arises in the first 1,000 km can often be clarified with a simple check without dismantling the engine — so it is always more economical to ask early rather than waiting and saying "it's warranty anyway".
