Hey guys, First time poster, but may I say what a dedicated community. I had no idea there was a forum this active just for discussing lubricants.
Anyways, the vehicle is actually an 83 amc eagle, but the motor is from a 93 cherokee, so thats probably a more accurate title. I was concerned about the level of material on my magnetic drain plug, so I dug out the old blackstone kit I had lying around, and sent in a sample. These are the results:
Yes, I know, I was using cheap garbage oil. Ive seen the error in my ways and switched to M1 high mileage 10w30 now.
Anyways, the question I have you you guys is this:
During the last oil change, I had added 12.5 oz of engine restore, to see if it would help my light oil burning problem. Compression numbers went up an average of 10 psi per cylinder, but the oil burning didnt change. Im thinking valve stem seals now, but havent gotten around to changing them yet. Anyways, the additive added a bunch of copper and lead to my oil, so its difficult to say if Ive got excessive bearing wear, or how bad it is. I know, I wont get a clear picture of that for another 2 or 3 OCIs, and anything else is mere speculation, but I was just wondering if I could get you guys' opinion on if these levels of copper and lead are in line with the use of the additive, or if they seem high even for this use case. That is, if anyone has experience with UOAs done with restore in use.
