Which 5W-40, if any, for Audi?

[TooSlick]

The Redline 5w-40, hands down....I'd also try their 10w30, which you'll find is plenty thick enough and VASTLY more shear stable than the overrated, Mobil 1, 0w-40....

Ted,

How does M1 5W30 fair vs M1 10W30 in a VW/Audi(VR6) application in your opinion.

Tooslick, what is your comment on Doug Hillary's remark above that claims about M1 0W-40 suffering from excessive shearing are misinformation?

Elf Excellium LDX 5w-40 works very well in my brother's 1.8t Passat Wagon. Here is the test results of Elf LDX 5w-40. http://www.turbofrogperformance.com/PDF_files/ExcelliumLDX5w40_Customers.pdf

I use either Castrol Syntec 0W30 or Castrol Syntec 5W40 in my 2001 Audi A4 V6 (59,500 miles). Over a 5,000 mile oil change, I noticed less consumption with the 5W40 vs the 0W30. Other than that, I can't tell any difference between the two.

I have not found that the UOA's that were posted on this site support that claim, especially at a no-more-than 5K OCI. I'm not a fanatic for the M1 0W-40, but just commenting that it has worked very well for our application.

I went round and round about this last year and decided GC was the best choice for my 2.7t. Like M1 0w40, it meets BMW LL-01 and VW 502.00, 503.01, 505.00, IIRC. But, it has a better addative pack than M1 0w40, it seems, and is a sheer stable heavy 30-wt. Excellent for Audi turbo engines, I'd asy.

What do you think is a rational OCI?

My initial plan is to stick with 5K OCIs because that's what the manufacturer maintenance specifies all the way to 100K.

The only other reason I can think of is that if and when it comes time to sell the car, I can point to maintenance records that show a manufacturer approved oil was used for all changes, according to the specified OCI.

Given the small sump size of the 1.8t and sludging issues with some of these engines, usually with 10K OCIs running dino, I think a 5K OCI is an excellent inverval, even with M1, GC, or Amsoil. My understanding is that's the current factory recommendation for this engine.

 

[Volvohead]

Just my opinions on the 0w-40, based on what I've seen and lived with so far:

Running a 10k OCI on that oil is NOT rational (in many, but not all instances).

Running a 5k OCI on that oil in SOME engines is NOT rational.

Running a 5k OCI on that oil in a turbo engine with a
I won't run it any longer than 3k in my R, but I will run it because it's great oil while it lasts.

By the way, the "factory recommended" OCI is the warranty OCI. It's designed to do exactly that - to get you through the warranty - and that's it. I can run GF-2/A1 dino 5w30 for 7,500 in my R and meet warranty. But I won't.

If I were a buyer of an older car, I'd be more impressed by positive UOA reports and a clean, strong engine than if the oil met some certification. But that's just me.

FTR- VW 502 sequence ~was~ preformed on an old 2.0l 4 cyl and is not therefore entirely applicable to a 1.8t, imo. All the buzz about VW 502...and it's an old spec from 1998 based on A3, which we have seen dino and semi-syns pass. I'd far prefer a MB 229.3/5 or VW 503.01 LL oil. Premium 5w-40s like AMSoil and RL would be great, but there appears to be a divide between basic A3-based oils like Belgian Syntec, which was developed for BMW, and super-premium like Elf, Motul, Delvac-1 etc. As for Mobil 1 0w-40, look for my buddy's UOA of Factory-Fill in his Dad's Cayenne Turbo. 19k and it was just getting ready to change.

Hi,
Rational OCIs - well we are into new territory here!

The "rational" OCIs using M1 0w-40 in Mercedes Benz engines (NA and supercharged) with ASSYST sensors are averaging about 18kkms (11k miles)
These vehicles have a 3 year unlimited distance Warranty in this country - and they actively seek Customer loyalty

The "rational" OCI using M1 0w-40 in all Porsche vehicles including the bi-turbo Cayenne is 20kkms (12k miles)
These vehicles have a 3 year unlimited distance Warranty in this country - and they actively seek Customer loyalty


Surely a "rational" OCI is what is recommended by the engine's manufacturer and/or what can be regularly achieved by using an ongoing UOA database on the specific engine with the one oil

Regards
Doug

Actually, the
Audi issued a Technical Service Bulletin mandating that all longitudinally-mounted 1.8T's move to an oversized oil filter that bumps the capacity up to 4.8 quarts.

Not a huge increase, but it's >4 quarts now.

Is the SM Mobil 1 0w-40 "watered down"? It still meets Euro specs, but I remember it being postulated that the additive levels have been changed. If it is less of an oil now, the 5w-40 T&S is a strong contender for $4/q.

Schaeffer #9000 5W-40 is my choice. Also worth considering are the ConocoPhillips 5W-40 "European" oils, 76, Kendall, Conoco, Phillips. All are VW 502 blessed. The CP oils have a HT/HS vis of 3.8, and the Schaeffer is 4.57.

Well, it may be an old test, but Audi engineers do seem to believe it's applicable for the 1.8T. Quoting Audi's TSB:

Engine oils with Audi Oil Standard VW 502.00 approval available in North America:

Audi Part No. ZVW 352 540S 5W-40
Castrol Syntec 5W-40
Chevron Supreme Synthetic 5W-40
Elf Excellium LDX 5W-40
Kendall GT-1 Full synthetic Motor Oil 5W-40
Mobil 1 0W-40
Motul 8100 X-cess 5W-40
Pennzoil Synthetic European Formula 5W-40
Pennzoil Synthetic European Formula Ultra 5w30
Quaker State Full Synth. European Formula 5W-40
Quaker State Full Synth. European Formula Ultra 5w30
76 Pure Synthetic Motor Oil 5W-40
Havoline Synthetic 5W-40
Total Quartz 9000 5W-40
Valvoline Synpower 5w30
Valvoline Synpower 5W-40

 2004 Audi of America, Inc. Printed in USA, July 2004 241.AUDI.APPROVED.OILS.CHART.FOR1.8LTURBO.94

Granted, the TSB is almost a year old (and probably misses a few brands), but I don't think they've superseded it as of today (6/27/05), AFAIK.

Not sure if it's significant or not that there are only two 30 weights on the list.

I'm not sure if that's entirely accurate in this particular case.

The maintenance schedule for my 2000 A4 lists scheduled maintenance intervals, including oil changes, all the way up to 100K miles for the 1.8T, and all the way up to 160K miles for the V6.

Yet in both cases, for the 2000 model year, the warranty only covered up to 40,000 miles (they've since increased it for later models). And Audi didn't mandate a change in OCI once the 40K mark was passed.

So that hypothesis doesn't quite seem to match up with the scenario that emerges when warranty duration and the official schedule are combined.

Now, if you said they're trying to ensure dealership service revenues post-warranty....

SynPower 5w30 DOES NOT meet VW 502 in it's North American formulation. Still "trust" AoA's oil recommendations?
