      Been wondering how my engine is doing with 336,705 miles on the clock. Been chipped since 40k miles and do extended oil change intervals using Mobil1 5W-30. Have gone as long as 22k miles between oil changes, usually change between 15-17k miles. In the early days of the extended drains I had the oil tested and it was pretty well done at 22k miles. The additives were all used up. I am still on the stock turbo also.

      #1 160 PSI
      #2 160 PSI
      #3 163 PSI
      #3 165 PSI

      Only major mechanical work was having the head rebuilt last year after a bolt failed on PD Performance Timing Belt Kit. We also used all the same lifters and the Camchain tensioner as well during the rebuild. I think the numbers are very good all things considered.

      Um, because it's my car. How many miles do you have on yours? Did you read the part where I stated the oil had been analyzed? If I wanted to follow the pack I guess the oil would be changed at your 5-8k interval. Some people change every 3k running synthetic, doesn't mean I will or should.

      My goal is to hit 500k before major engine work, bet I will make it. I was also one of the first to tear into a Tiptronic tranny, found out the uber high priced VW fluid was no better than $4 a quart Mercon V which I now use in it. Have had no oil related failures in the engine or tranny, so I must be damn lucky or actually onto something. I probably get away with this because 99.9% of my miles are all hiway. Would not be pushing it so far in typical mixxed mileage driving.

      Nice!
      My AWP at 71K miles had 185, 185, 186, 183 PSI.
      I also do extended oil changes (up to 7.5K miles so far) based on oil Analysis after each oil change. I also added an AMSOIL Bypass oil filter to remove all the really small crap in the oil.

      just saying that if at 22k the oil was finished like you stated i would drop the intervals a bit.

      oil looses it heat absorbing characteristics after time and there for friction will increase. causing increasing engine ware.

      the highway is probably the only reason the motor has made it to that kind of millage with out engine work.

      im not telling you to change your ways..im just thinking the same way everyone else does and keeping the oil fresh and clean.

      anyways hey your motor still runs and thats what counts if it works keep it up

      You are clearly the 1.8t maintenance god. I am planning on keeping my 04gli until the bitter end, this and your other high mileage threads inspire me. I worried chipping the engine would decrease reliability, not a concern anymore.
      You do all the maintenance yourself on the car?

      Not a god, just a bit of luck along with keeping on top of things. Yes, I do all my own maintenance.

      Looking good. When you look at compression your looking for variances. like 160,160,160,140. Since your ~160 all across youre in good shape!!!

      I wouldn't say "good" shape. Maybe fair. He's loosing power thru cyl pressure lose. To each is own. I'd be pissed I was loosing 20 or 30 horse and rebuild that thing.

      And think what kinda compression you'ld have if you changed oil every 7500 to 10k. Might be sitting around 175's.

      How do you think weather and the high volume of mileage helps with the longevity of your motor? I drive about 25k a year and live in the northeast. Everything else being the same, I would guess my engine would not last as long as yours.
      At my current rate, and current mileage, I wouldn't hit your mark on my 04 until ~2020. Love to see my car last that long.

      Want to bring back from the dead, how did your cams look? How do they look?

      My 183k 02 AWP had flat intake lobes and I think the cause is the zddp cut in 2006 or so. I replaced the flat cams with 3651 cats, and now add lucas tb zinc + to the oil.


      Lots of flat tappet cars are wiping cams as of late from the zddp removal.....

      Holy **** just saw this linked from another thread. My 01 has 215k or so, and I'm astounded by the condition of this engine. Cross hatching looks perfect and there is no ridge the top of the cylinders at all. Even the valves that aren't bent look super clean, no evidence of weak valve seals

      Kinda, the gauges are all over the place from one gauge to another.

      The specific heat of oil does not change as it "wears out" unless it's just getting full of water, in which case it isn't 100% oil anymore...
