In my signature below. You must upload the pic to a host server, either here or something like Imgur. Then post the image link back here in your thread. It should show up inline like you want.

I would go to www.imgur.com upload the image there and once finished you are going to get different options for types up links you want. Select the appropriate one for message boards and forums, copy it and then past it here.

Okay, my 70,000 mile service was just done and I had the Blackstone lab do the test on 10,000 dealer-serviced Castrol.
It was all normal except the Potassium was 40 and the normal for Potassium is 22.
Also, the fuel percent was high at 3.5. And the flash point was 375.
They commented that maybe my use of Dieselkleen might have lowered the flashpoint.
Blackstone commented: "Potassium is a coolant marker but without high sodium (or poor wear for that matter - metals are in good standing) a leak is just a possibility at this point."
Comments? Could the VW tune cause higher Potassium levels?

Solvent based additives will reduce the flashpoint. Winter or All-in-one formulas like stanadyne PF are solvent based. I don’t use Diesel Kleen and unfamiliar with the constituents.

Don’t use these ^^^ unless necessary. If your fuel doesn’t gel or live where temps are mild use a summer formula which typically don’t contain solvents.

The patassium is a mystery and could be from the additive. You only have one data point so it’s difficult to speculate on where it’s coming from.

Potassium is generally indicative of coolant.

Yep your correct, CRs do have high FE and Al levels , mine are high but pretty predictable,Al always seems to be half the PPM of FE. Mine are touching 110 FE per 15k(10k miles) and 55 Al. Only thing I'm worried about is the potassium levels in mine which are the same level as Al but again they seem to be predictable.

I just got into the game and learning. I haven't been able to transfer the files to post yet, but will as soon as possible.

I had Blackstone check both my 2017 (20k) Subaru 2.0 & 2011 (70k) CR JSW. The Subaru numbers were VERY low relative to the TDI??? I wondered the same about the TDI levels that seemed way high. I did add half a bottle of moli lube additive @ 3k into it. I realize it was my first oil change (on 7k) since purchase (CPO), so...? The Subi I bought new and changed every 5k w/ recommended synthetic oil (6k recommended).

Why are such high wear levels common to the CR? I always was under the understanding diesels wore soooo much longer. You know 1 million mile trucks. My guess is the emission related deficient oil now used along with modern diesel?

This is the first drain trying out Redline 5W40 oil after using Mobil TDT for the last decade. ~19K miles was not intentional, but, life happened and it is what it is now.

It might be time to take a peak at my cam lobes and lifters. The last look was 20K miles ago during timing belt change and all was well. It's still on the factory cam.

Or, maybe 19K miles was just too much? Thoughts?
