Because a $30 specrographic analysis doesn't come close to giving "results" on all the aspects of how the oil performed in your long OCI. Go look at the entirety of the tests comprising a VW approval and see how many are characterized in this inexpensive analysis.
Not everyone on here tells people to get a UOA so they can use it for something wholly unwarranted.It's ironic.... Others ask "how long of an interval can I do" and a standard answer is "get an oil analysis". You did, it shows things are not bad at all, yet you still get critiqued.
She runs like a top !
Twice actually
It leaks oil then ? You had to add (4) quarts over time, which admittedly, isn't a lot over the mileage you're going.
Definitely doesn't leak. I guess burns a quart every 10k or so
can you send some pics?
Good. I had a 2015 Passat TDI and put 62k miles on it in 2 years and 3 days till it was bought back by VW for the diesel gate thing. I was going to keep it but hit a deer hard a few months before the buyback and ran the numbers and realized I would never get more money for it than what vw was offering. I changed the oil every 10k or so and when I changed the dsg fluid it looked brand new so the highway miles were certainly easy on it. Great car that ate up the highway miles in comfort. I achieved several 900+ mile tanks which is amazing for a car that size. Btw i don't remember ever adding oil btwn oil changes. I did have to add some the day I bought it as it was low upon arriving home with it. There was a thing about them being underfilled from the factory and the amount shown as required in the owners manual which VW sent a replacement page for the manual to correct.
Running ridiculous OCI and gauging the effectiveness of that practice with what are essentially useless UOA? Not exactly stuff I want to see.
I would be curious if he is running a bypass setup.
No bypass filter, just plain old mahle filters every 10 or 15k miles. Amsoil 5w30 euro
Yupper!
Yep. Relative compression test with a scope and a leakdown tells a lot.
