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:
5k base 7.5k recent
Iron 19 14
Chrome 2 0
Lead 1 0
Copper 2 2
Tin 0 0
Alum. 3 4
Nickel 0 0
Silver 0 0
Silicon 7 2
Boron 85 49
Sodium 2 5
Mag 152 418
Calcium 2788 2540
Barium 0 0
Phos. 1143 1175
Zinc 1387 1326
Moly 82 6
Tit., Van., Pot, - All zero
Fuel Less than 1 less than 1
Visc. (100) 14.31 13.67
Water 0 0
Soot/solids .13 .37
Glycol neg neg
Nitration 11.0 12.0
Oxidation 12.0 14.0
TBN 10.29 10.15
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.
