If you are referring to Amsoil AFL 5w40... knowing what you know, why would you NOT use it?wjdell said:I believe its the best 505.01 out there - AND I CAN NOT USE IT -
That is the TDI "sweet spot", from about 84-90 mph indicated. The car will definitely go faster, but you start to run into suspension limitations if you are stock.a friend drove my car today on the pike at 86 and for 1 hour. At about 3000 rpm and it was very nice.
i think everything is looking fine for this young of an engine.dhdenney said:Does everyone think it looks ok considering it's an uapproved oil? No big number jumped out at me.
Be careful about that, WJD. I've seen stuff on the net (from Motul) that claims that only light-viscosity oils can qualify for 505.01. No 20W50, ever.wjdell said:Well Valvoline is not AMSOIL and clearly claim that their full SYN oil 20W50 is 505.01, this is a oil company that has submitted to VW testing and has a oil is on the approved list. Seems to me they would be trustworthy. Its lower TBN of 7 is much inline with 505.01 oils - 10K.
TornadoRed said:Back on June 13th I posted UOA results on Delvac 1 after 9566 miles, as I prepared for a test run using Elf Evolution 0w30 meeting the VW506.01 spec for extended drain intervals.
I received the results of a UOA test after 10674 miles using the Elf, and I'm very unhappy. Not only did I not observe any improvement in fuel economy, but the wear numbers look terrible. I'll be changing out this oil and going back to Mobil Delvac 1 5w40 later today.

d2305 - it turns out that a lot happened during this OCI that could have effected the UOA results: boost/turbo leak occured and was repaired, timing belt was changed, airbox opened/air filter replaced (dirt ingestion doubled from previous OCI - i.e. Si went from 5 to 10ppm), oil soot loading increased 33%... we can't know if any of this did or didn't effect the data the lab returned - and that's why the repeatability of results is important. and, conclusions can not be drawn with only one or two data points.d2305 said:TR I was suspicious about the 506.01 oils and your numbers confirm that it's not a "super oil" ...
FYI - below is a link to the first 10k UOA I recall seeing with the new AFL. please remember that while this AFL UOA is not great - it's just one UOA and conclusions about AFL can not be drawn with only one or two data points.Time to try Amsoil ALF.
I think these are connected. Until the boost leak was fixed, I was getting a lot of exhaust smoke -- which is very unusual for my Golf, because it never manifests any visible smoke. Anyway, that's my hunch for why the soot was so high.SUNRG said:d2305 - it turns out that a lot happened during this OCI that could have effected the UOA results: boost/turbo leak occured and was repaired... oil soot loading increased 33%
No, it won't be better -- but I'm going to guess that it won't be a lot worse. Okay, the silicon didn't go away, so the iron is probably going to be even higher. But the soot may not be much worse, and the TBN may be only slightly lower...TR did send a second 506.01 sample to the lab with ~14k on the oil - but considering that the dirt and soot are already present in the oil, i wouldn't expect things to have gotten any better since 10k...
What oils are called for in your manual? (API/ACEA/VW specs)coal_burner said:... My owners manual said that the oil I use should have some or all of the following certifications......
The Mobil1 Truck&SUV had the most matching certs so I bought it.
According to my owners manual, I did use an oil that is approved in my car...
Excellent point!d2305 said:That's interesting, I wonder if these labs are just random number generators?
here's a link to the previous two analyses on this oil sample - LINKSloppy Snood said:Sloppy's 4th UOA from Oil Analyzers Inc. is available. Oil is Elf Evolution 0W-30 CRV 506.01.
18,110 miles on the oil.
42,180 miles total on the 2005.5 Passat GLS.
Viscosity @ 100°C: 11.70
Water : 0
Coolant (glycol): no
"No corrective action required. Oil is suitable for continued use. Resample at next regular interval."
As stated previously, Sloppy's running Elf Evolution 0W-30 CRV 506.01 as of 24,070 miles. Oil change has been completed after a Motul Diesel System Cleaner treatment. New Elf Evolution 0W-30 CRV 506.01 added to the motor following the Motul treatment.
What say you AndyH and SUNRG?- Sloppy Snood
While I understand there is not an exact number or science to automobile "break in," how long does it usually take with the newer PD engines? Does some have a PD engine that is considered to be "broke in?" In particular, I am speaking to the 2.0-liter PD diesel engines that operate at much higher pressures than the 1.9-liter engines.SUNRG said:if this pattern does repeat itself is the question - i think there's a good chance that during subsequent 18k OCIs the final OSI 6-12k will yield low wear rates because amazingly your engine is still wearing in...cheers!
