#4442165 - 06/26/17 05:58 PM Rotella T15W40 22K on the oil (making metal)

Well not happy with these results at all, Blackstone is recommending I drop the oil as iron is now at 95 ppm. Most of the miles are city/highway and towing in the west coastal mountains. As a comparison my sister's 6BT has very similar miles on the oil and is 12 ppm (no towing). I've got no signs of trouble at all from the engine, no smoke, blow-by is low and fuel economy is excellent. What do you guys think, dump the oil or keep using? I'm inclined to dump it, change the full and add 15 quarts of Amsoil AME 15W40 and see if that helps the wear numbers.
Here's the report:

From using .5-1qt to 6. There is a problem starting to happen. It's not the oils fault.

At what point in your OCI did it start using oil? That's probably when you should change it. I've had a passenger car that would use zero oil, hit 7k on the OCI, and then start to use a little bit.

Here's the report:






What oil was used for the previous OCIs?

Edit: interesting that back at 248,000km it used 5qts make up oil in 8,000km. Then went down to none over 17,000km. Now up to 6qt in 35,000km. Are those numbers correct?

I ran Rotella T6 for 40000 miles in my Detroit and was it 75 PPM iron, that was before I started playing around with bypass filters I did swap the full flow filters at least once which added 2 Fresh gallons of oil, I have a bypass on three trucks only 2 of them have regular sampling done right now. My one suggestion would be to possibly use oil to flush out that high mileage oil (shot oci), just a thought because one truck had more frequent oil changes than the other and my samples and tbn reflect that. My 200,000 Mile motor versus my 1 million mile motor the samples look better on the 1 million mile motor. The 200,000 Mile motor oil change interval with 40K prior to the bypass install and regular sampling the 1 million mile motor had a 15000 mile change and an oil pan dump and cleaning just prior to the bypass install. I think the residual oil from the 40K change is causing me to see a 5.2 TBN in that motor versus a 5.8 in the other motor at the same mileage sample. Just some interesting thoughts so far I'm very happy with the Shaeffer 9000 and fuel mileage I'm receiving from it

Sorry guys I forgot to mentioned that this truck has an Amsoil Dual Gard and a Frantz in series after the Dual Gard. The 6 quarts of oil are used from 4 toilet paper rolls changed, a full flow filter changed, and the oil burned is around 2-3 quarts burned.

Is this the same filter setup as previous OCIs?

Yes, with the exception of adding the Frantz unit, this was added 12000 miles ago.

I'd be interested to see a particle analysis on that, Blackstone told me it's only $15 if the oil is clear enough to do so

Well I tried that with the previous sample and they could not read it, have to be able to see through the oil.

I know it may sound counter-intuitive, but is there any way to bypass your frantz filter setup for the next change?

So, bypass your bypass filter.... crzy

I'm just trying to cancel out any obvious variables that may have changed AND affected your UOAs before we blame the oil.

35,600 miles or kilometers on the oil?

Thanks for the responses guys, I've decided to change filters and oil and get another sample in 5000 miles.
