This is an update to my previous post. This 10k mile sample was taken with 90k miles on the vehicle and is listed as the 3rd entry in each row. I am still using Delvac 1 and running ARCO ECD-1 ULSD with Primrose 405/402 as my fuel. The only new modification is a CAT 2 micron fuel filter. Below is my previous post with my new data included. This sample was anaylzed by Blackstone.

A little background…..

I bought my 2000 Jetta TDI 5spd last Fall with 54k miles on the odometer. The first results were from the initial baseline sample which the owner estimated had between 3k and 5k miles. The baseline sample was before any modifications. I don’t know what oil was in the car. Any guesses based on the additive chemistry? The maintenance records were not complete so I opted to run double Auto-RX cleaning cycles with Delvac 1300. After the cleaning and rinse cycles were complete, I switched it over to Delvac 1. The second set of results are from my most recent sample. The recent results reflect the modifications listed below. Here are the details:

Miles on oil: 7,500

Miles on vehicle 70,000

Driving conditions: The oil was in use for the months of March-May in Southern California. My driving is 80% Highway (usually 70-75 mph) and 20% City. I don’t baby it.

Fuel: My fuel was exclusively ARCO ECD-1 ULSD with Primrose Powermaster 405.

Oil/filters: Delvac 1 with Mann oil filter and Mann air filter.

Mods: Rocketchip Stage 2, Sprint 520 nozzles, Diesel Geek Race Pipe, Old Navy CCV

Lab: Testing was performed by CTC

RESULTS:

Fuel Less than 1, less than 1, less than .5
Visc. (100) 14.31, 13.67, 79.1(15.8?)
Water 0 0 0
Soot/solids .13 .37 .4
Glycol neg neg neg
Nitration 11.0 12.0 ?
Oxidation 12.0 14.0 ?
TBN 10.29 10.15 8.00

I am very happy with my results. The iron is right on, air filtration is working well, and lots of TBN left. The only area that I see for improvement is reducing my soot level. Any suggestions for an additive? I specifically am looking for something that increases lubricity and reduces soot.

Based on these results, I will be pushing my next interval out to 10k.

Any comments are welcomed and appreciated.
 
Isn't the soot spec up to 2% on the TDI?

Otherwise, great looking numbers. Did you retrofit the car with the 100k mile timing belt parts?

The 'base' fill of oil looks to be quite appropriate based on the numbers you provided. Sometimes you see the TDI's filled with bulk 5W30 dino, which isn't very good for the turbocharger.
 
I'm not sure what is considered a maximum level of soot. I think some may use 2% but I personally don't think I would ever let it go that high.

Yes, at 60k it got the 100k belt, tensioner, all rollers and a water pump. I should be set to 160k.
 
Try Fuel Power instead of the Primrose fuel treatment. Or, get some Schaeffer Diesel Treat 2000 from SaleRep. You might also try Lube Control in the oil to keep the soot from agglomerating.
