I do not know why they didn't combine all 3 together.

copper went from 21 to 28 ppm from 11k to 45k, that's excellent. Hopefully this oil change it will all be flushed out of the system. I'm going to cut apart the filters and see what's inside.

A couple other things:

TBN is down to 8.6, the first sample was 9.6, this shows the new CJ-4 oil(CI-4 was used in the first sample only) has a lower TBN, which seems to be common knowledge.

Soot went up from the first sample, .1 to .3, due to summer vs. winter conditions.

I'm curious why my tin went from 2.7 to 0 when I didn't change the oil between 2nd and 3rd sample. Lead, silver, and aluminum also went down. Either this shows that the sampling is erroneous, or the extra filtration REALLY works. But I had the kleenoil filter on after the 1st sample.

"time on unit" is + 1,000,000 km.

Around the 25k mark I added 1 gallon of make up oil.

how many rebuilds on the engine

 

[allan5oh]

one, around 900,000 km. Motor hasn't been opened since.

----, didn't come out quite right. First column is observed values. Second is "new oil" values for 2nd paragraph, and "abnormal" for 3rd.

Although abnormal doesn't change if I have 11k or 52k on it...

BTW, thats .46 PPM per thousand miles.

.46 ppm iron, where's that ---- edit button!

Oil and filters working extremely well here. Was this the engine with the previous scare(or 2)?
Do you plan on switching to a synth for the winter? or at least plugging the coolant/oil heaters in?

You're at 45kkm here, and it looks like that you should have no problem going 100kkm with nothing but top offs and filter changing.

The power of your bypass filter showing as it cleans your oil, which reduces wear, allows longer OCIs, removes built up wear......

If it wasn't for the upcoming weather and cold start issues(wear, oil flow...), I would just use this oil year round.

I don't know what I'm going to do, probably just run schaeffers 5w40 this winter. We'll see.

I saw an SAE test where it took 20 seconds for 5w40 to get to the valve train vs 80 seconds for a 15w40. This was in a m11 and the oil was -15C.

Yes, this is the same engine with that copper problem.

52k showed 229 copper, changed oil and filter

11k showed 21 copper, no change

45k now shows 28 copper

Hopefully everything is fine.
