Ok after my panicked sludge cleaning thread (thanks for all the great guidance to everyone) here's where I am and want recommendations on how to continue to finish my engine clean up.
Currently running 1QT MMO in 6 QT oil full syn change. (1:5) I am in 250 miles now. How long should I go (500? 1000? total miles?) Filter looks dark amber but not black at this time.
As a reminder I am trying to do a gentle but thorough cleaning after finding mud like sludge and an oil light (which went out when the sensor was changed- thinkgin it got plugged with sludge). Trying not to do a flush as it seems the engine is not that bad based on hwo quickly it cleaned up so far.
I've read through plenty of threads on how to do a cleanse to clean up an engine and I want one last process to finalize before I go to standard OCI with a high quality synthetic.
I have settled on the Diesel OCI and want recommendations:
What grade to use? Its cold here 15-20 degrees starting in the morning. Car calls for 0W-30. Diesel is not available at that visc. Use single grade?
Use Conventional or Synthetic ? Any special approval (SN1 AP CEA ?? required?)
I've used Rotella in my Turbo Saabs before, seemed fine, so it's a known thing to me but Delvac is also recommended.
If Rotella which to use (T1, T5. T6, TX?)
How many miles on "short changes" are recommended? I can pull the filter at any mileage interval. it's a cartridge type and easy to get to so it's easy to pull.
How many changes before I swap to Mobil 1 ESP ( my go to)
Thanks again for any opinions
