Alright, with all of the oil debates, I figured we should see who has over 100K or 200K or more. Please post how many miles, what brand and weight oil you have been using, and what brand oil filters have been used. Also, if you have had an engine internal mechanical failure of any part of the internal engine, i.e. rod thrown, bearings wiped, rings bad, etc. that may or may not have been a result of the engine oil, please also note that. Lastly, please state how many miles you go between oil changes, and if anyone has any oil analysis reports from the CRD, that would be helpful as well.
Example using my own CRD:
I have 79K currently. From 0-47K, it had dealer oil changes, which were 0w40 Mobil 1 up until Chrysler went to Pennzoil Ultra 5w40. Not sure when that occurred. Oil changes were every 3-6K I think. When I got it at 47K, I changed the oil with Mobil 1 5w40 up until 73K. I used Pure One (Purolator) PL25230 oil filters every 4500 miles/1.5 months. Since 73K, I have been using Rotella T6 5w40 synthetic at 4-5K intervals using the same Purolator P1 filter. No internal engine trouble to date.
Next few oil changes will be with Mobil 1 0w40 and P1 oil filters. If the Blackstone test kit arrives in time, I will try to get a sample of the RT6 5w40 off for analysis, and will do the same with M1 0w40 during the 2nd oil change with M1 so that the test results are fairly accurate. Again, that is if all goes according to plan.
Lastly, see my other post regarding comparing the factory Mopar oil filter and the Purolator PL25230 oil filter.
