Shell T6 5w40 10k mi, 00 Audi A4 1.8t ATW K04 chip

[lucaq]

This is my first UOA. I changed the oil with the turbo last year. I had only had the car a few months and I did a Kinetic Exhaust Manifold, APR exhaust, Borg Warner k04 turbo (new), new oil feed line (just for safe keeping, coke buildup in the line is a problem in the S4, not so much in this car), valve cover gasket w/ tensioner gasket (head looked clean, no signs of sludge), New air filter (VW/Audi brand). Car had 120k on it, just over 130 now (I bought it with 118). Regularly boosts 18 psi and has a larger Side Mount Intercooler (SMIC). I run OEM oil filters only, not exactly sure what was on it, but it was probably Mahle. Stated oil capacity is 3.7qt, it was very low when I changed it (I was worried once I made this realization, I also thought that it would affect the UOA).


Comments from analysis tech:
Code:
Iron is a little above average in this first report for your Audi, but that's

perfectly normal considering the length of this oil run. Universal averages for the

1.8L Turbo engine are based on just ~5,900 miles on the oil, and since iron is the one

metal that should track with mileage, it makes sense to see it reading a little high in

this report. The other metals should stay pretty close to average levels regardless of

mileage, so everything here looks great. No contaminants were detected and the TBN was

good at 3.6. You could try12,000 miles next oil if you want. Nice!

Looks great for almost twice the universal averages. It's sheared almost out of grade but wear metals are low so it doesn't appear to be causing any issues. You could go a bit longer on it next time.

Keep the oil level topped up and enjoy the go-fast goodies!

The universal averages from B/S are pretty much much useless and I would not compare a given vehicle to them.

 

[skyship]

Their universal averages are quite usefull although you do need to ask for the average mileage they are based on, as they sometimes forget to tell you. Until you have established your own set of normal averages, some averages are definitely better than no averages, which is what you get from the other labs.

I've found them to be very useful for comparing my engine's UOAs to a larger population. But if you don't like data...

Regardless, the UOA is absolutely fine. I would continue with the current regime aside from keeping the oil level topped up early & often.

 

[Donald]

The problem with the B/S universal averages is they are for the average mileage for that engine or vehicle & engine.

So if your OCI is 3000 and the universal average OCI is 5000, then even if your values are equal to the universal average your UOA is worse. And it would be difficult to normalize them for mileage. Most of the time they tell you the OCI average, but not all the time.

If universal averages were great, Polaris would be using them. They certainly have a lot more data than B/S they could use to come up with universal averages.

The only way is trending your own vehicle and knowing what the abnormal values are.

Every time B/S has made comments about my vehicle compared to the universal averages, they have always included the mileage to which the UA refers.

From my first Blackstone UOA:
"Universal averages for wear metals in oil from this type diesel [engine] are based on a 7,800-mile oil run"

You can get a pretty good idea by simply taking the your OCI divided by the universal average OCI and multiplying by the wear metals figure to get a corrected number. Works perfectly for Fe and is fairly close for other wear metals. You will get an error as the filter gets dirty and its efficiency increases because some of the original wear metal particles then get filtered out, but top up oil will probably cause more of an error.

Don't worry I got this.

Donald Amsoil likes universal averages.

Geez, that's a good report! 10k on this engine is pushing it, but T6 did the job. I think I'll be moving my 2001 Passat resurrection project onto T6 after I put a few hundred miles on the current fill. (This is what you will be able to avoid by using T6 instead of a conventional oil: https://bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2904251)

Make sure you go to the larger filter for this motor. Audi switched to the diesel filter a while ago, it adds nearly a quart to capacity, about 4.5l total. Part number 068 115 561B. Its a Mahle OC51, Mann 940/25 and a Bosch 72174
The older number was a Mann 719/30 or Bosch 72150. Also have you upgraded the diverter valve?

 

[Gasbuggy]

Impressive. You were only a half quart low. I would put an extra 1/2 quart in it when starting fresh rather than have make up oil in should you plan on testing at 12k.

 

[lucaq]

Upgraded from the sludge upgrade? So there are three sizes now, old audi 4cyl block, passat/a4 sludge upgrade and now a diesel filter? I will definitely look into this, awesome, thanks!

You kinda have to upgrade the diverter valve when heading towards 20 psi, the stock ones are notorious for failing, I think that even the 710N OEM DV would probably fail at some point. My friend's shop is an APR dealer, so I got the exhaust, inlet pipe and R1 DV, all APR from them for a decent price. I do have two of these cars under my care, I am running the same regiment on an 03 A4 AMB engine code, just changed the oil in November, so we will see how she holds up, she has a K03s (stock) and pushes almost the same boost as my K04. She has a DV also, but I am not sure the brand, it was anodized purple

and came on the car when I got it (REVO chip too). She has 200k miles, I am really interested to see what kind of UOA I get on her, maybe I won't push her to 10k to start.

Bummer about your passat. I actually have the same fear about oil pressure/oil pump so I installed a oil pressure gauge along with the boost gauge on the steering column. There is an open test port on the oil flange anyway so it is a really easy install and the stock setup is just an oil pressure switch, basically only helpful in a catastrophic scenario as it only trips if the oil pressure drops below a threshold. I like having the oil pressure gauge on a car with as many miles as the 03 has (the car with 200k), I can see when the oil warms up just by pressures (100 psi when cold in the winter, I drive it nice until it normalizes) and if something not cool starts to happen hopefully I will see some sort of representation of the event in the oil pressures. Funny, what inspired me to do oil pressure is that I rented a truck that didn't have a tach, but did have an oil pressure gauge.

I like the B6 audis, in fact, I would love to have another 1.8t B6.

I just called my friend's shop and ordered 4 of the filters that you referenced. Mann is OE is what he told me. They were cheap too, like $6 each.

 

[Audios]

Yes, this is the sludge upgraded one, not sure if you ran it already. This also fits on most Vw 1.8ts, and 2.0s. For the extra dollar or so, we put them on any of those engines when we can.

Oh, I was running a sludge TSB filter already, I was under the impression that there was yet a bigger filter, oh well, always nice to have them on hand... Yeah, I ran them on my Golf 2.0 ABA as well with extended OCIs (never did a UOA though). The Golf got hit and moved to mexico, so hopefully she is still working hard, just not for me any more. Sucks when you take the effort to care for a car and then someone else's carelessness makes that care a waste. The teenage girl that hit me had the nerve to say how my replacement A4 was nicer than my golf anyway. Childish thinking. The Golf was paid for, reliable, economical, fun, functional, stylish, everything one could want in a daily driver and she ruined that (sniff sniff). I got paid $2,200 for the golf, but I had to pay $5k for the A4, so she really did cost me money, even if she thinks that they paid me fair value for my Golf. Sorry for the tangent...

Not bad for an oil that isnt not really supposed to be pushed that far in an gasoline engine!

I just found out this little tidbit from TDI Club:

Contacted Mann+Hummel in Ludwigsburg, Germany and got the following info.

Passat B5 (AHU 66kW/90bHp) 10/96->12/00
specified in catalogue: W940/44

It is FINE to use the W940/25, this is the actual email I got back,

Dear Mr. Murphy,

thank you for your inquiry.

Please note that W 940/44 is the "longlife" version and can be used 30,000
km.
W 940/25 is the old version but can be installed as well without any hazard
for your engine.
However W 940/25 has to be changed after 15.000 km.
