Romke,
Through Oil Analysis. We sample every 12K. Our units with the DPF have 200K on them. We did not se this using CI 4plus engine oils. Since we have 120 units on CJ 4 we made the move over to the whole fleet. No other levels have increased. My concern is what effects is oxidation or...
Why am I seeing oxidation levels rise in our new EGR-DPF engines. Levels have risen about 6%-8% versus just an EGR engine. We are using the new CJ4 oils from a major supplier. Any advice is welcome and Happy Holidays
