Another data point for folks looking to compare their numbers. transferred to favorite links
Vehicle: 1998 Jetta TDI
Mods: None except for "yellow light" EGR mod
Air filter: OEM paper
Oil filter: OEM, changed at 5K intervals
Bypass filter: None
Oil: Caterpillar-branded Delvac 1
Fuel: Amoco Powerblend with ~8 oz Power Service Diesel Fuel Supplement (last ~1500 miles 65/35 mix of Powerblend and World Energy B100)
Mostly highway mileage. Total vehicle miles ~74K.
What say the experts - would I be pushing my luck to drag it out to 20K?

During the first interval I brought the car to the dealer to diagnose what looked like failing turbo seals (oil dripping down onto the inner CV joint). The dealer cleaned up the area around the turbo and added a tracer to the oil, and when I brought it back after about 100 miles they held a black light up to it and determined it was a loose oil return line. I don't know what the chemical makeup of the tracer was, but it didn't seem to skew the analysis results any.code:
