It might be hard to believe but I happen to own an 03 MKIV Jetta TDI with about 64,000 miles. I've owned the car for about a year when it had 46,000 miles on the clock. I bought the car from Carmax, which wasn't my 1st choice but there aren't exactly too many sub 50K MKIVs laying around these days. They claim to do a full service, fluids, etc. So I ran it for 9,300, changed the oil with Valvoline 5w 40 and took a sample. What I got back was a little worrying. I ran it for another 10K and took a sample and they couldn't hardly believe I ran it for 10,000!
So... what do you think explains the differences between the two reports? And how do my numbers look now?
