Hi,
this UOA is the first on a new engine. The factory fill oil was a MB229.1-MB229.3 Approved product of Ssangyong Oil, Korea. It was changed after 2270kms, 1410 miles, when the drive line components and PS were changed to synthetic lubricants - Castrol Syntrax 75w-90 and Transmax Z
An OEM MANN licenced oil filter was used
The engine was new so it is obviously still bedding in. Operational use has been primarily 70% highway with off road at 25% and urban at 5%
Engine revs were restricted to 3500rpm up to the OC point. Then they were restricted to 4000rpm up to 5000kms. The engine's red line is at 4500rpm
The oil will now be changed according to regular UOA results using these limits: Soot 2.5%, Iron 70ppm, TBN 2, and/or any other significant oil degradation factor. A time limit of 15 months will be applied too. The engine will operate in an ambient range from -5C to 45+C with much of it off road
The Manufacturer's recommended OCIs are; first OC at 5000kms and then OCs at 10000km intervals using MB229.1 or MB229.3 Approved and Listed lubricants
