Hey oil gurus!


Disclaimer: my first TDI, my first EGR equipped vehicle, not my first diesel.
As you see in the picture that is oil color after 100 miles, yes one hundred miles driven on it.
New to me 05 Passat TDI with 190k miles. I have receipts and car fax confirmation that vehicle has been serviced 7k-8k miles at the shop that out Pentosyne oil and OEM filters. Vehicle does not smoke, no blow by, turbo solid. I changed oil with Rotella T6 15-40. And drove total of 100 miles, 50 of it freeway speeds. And that the color of my oil.
I'm comparing it to my 01 Cummins with 110k miles. On Cummins I get that color after maybe 2k miles.

Is TDI run different? Is that because of EGR stuff? Or is it because different oil is now "cleaning" things inside?[Linked Image]

Yes, that is normal. I had a 2012 Jetta Sportwagen TDi that would turn fresh oil black on a trip around the block. And is was serviced at 7k intervals with Mobil One ESP since new.

Looks like any typical diesel and I've owned a few. If you have a diesel showing clean oil after a couple thousand miles that is highly unusual.

it freaked me out for a bit guys! I used to seeing that toward the end of my oil change intervals on my cummins. And on my cummins i do 5k miles on Delvac 1300 (conventional).
This this passat is new to me, i might run 5k and do oil change and maybe do a oil sample test. Just for peace of mind, but my goal is to run 10k on rotella or see if i can get some mobil ESP.

OP, you are not the first owner of a Diesel to post here on BITOG about finding the oil looking black after a short time of running in a Diesel. It is normal and nothing to worry about.


Boy will I be happy when ALL vehicles on public roads are autonomous.

this is common, particularly if you don't drain the oil filter housing, it holds about 0.3 liters of oil. Usually this is enough to make the new oil go black instantly

if you drain the oil filter housing your oil might stay "clean looking" for a day or two



LOL

If your Cummins takes 2,000 miles to turn the oil jet black.....You're changing the oil far to often! My old '97 12 valve's oil stayed clean for about that long after pulling the engine to replace the oil pan & gear case gasket. But after a 8,000 mile run & oil change....It would turn the oil instantly.

Facts of life for a diesel engine, Of coarse....EGR & DPF only cause more soot loading of the oil.

Couldn't actually get a good taste. Had to do a shot of it to make sure it's clean.

Eventually I'll get rid of EGR. But for now I want to determine the base line for the car. Since I just got it.
And yes, I do change oil on my truck often. But not really. I put about 5k miles a year, so I change it once a year.

DO NOT USE THE WRONG OIL on VW Diesels. They need the correct vw spec oil because of the weird fuel injection, the wrong stuff will wear the cam shaft.

Fine carbon black soot does that. It doesn’t take much to look fully dark black like ink.
