I just did my first oil change since I bought my '15 used in July. I went with the Liqui Moly Molygen 5w40 (bought the ECS kit), and I guess time will tell if it really matters.

Pretty annoying.

If you want any of the magical oils people are talking about you almost certainly have to order it and have it shipped.

Mobil 1 was the only 0w 40 I could find around here within normal driving distance. Guess I'll have to plan better on the second go around.

GTI doesn't specify 0W40.

No, but it does specify 502.00 which M1 0W-40 meets or exceeds. The first number being "winter" viscosity, or the "cold" viscosity, is rather moot at operating temps and the difference that a 0W has over a 5W as far as cold pumpability is nominal. The viscosity spread for a 0W is usually a function of superior synthetic basestocks. Need to focus on operating viscosity, shear resistance, dynamic film strength etc. much more than a W rating.

Agreed, but it sounded like you were specifically looking for 0W40:

Just eliminating confusion for the lurkers here. It's not about 0W40. It's about VW 502.00, 503.00, or 504.00 (as of the writing of the owner's manual).

In addition, VW specifies that the factory fill was 5W40 or 5W30 and that such is suitable for "normal driving in all temperatures".

Liquimoly 5w-40. Have run it in my mk6 as well as three tuned bmws. Good stuff on 5-7500 intervals.

Definitely my bad for not specifying.

Yeah, I could not find 5w40 and did not want to use 10w30 so that's how I got to the 0w40 Mobil 1.

Ordered some LiqueMoly 5w40 so I'll just run the M1 for 5k and change in the springtime again.

Gotcha, good call.

I want to see the INTERNAL memos from VW about what oils are suitable for "track-day-oriented driving".

I grew to appreciate Honda's maintenance minder, that looks at your driving style--cold starts, revs when cold, revs when hot, ambient temperatures, and so on--and weighs it all together and comes up with a "change oil now" warning that's dynamic per your driving style and environmental conditions.

There's good reason for VW to adopt such a thing. The computer may not KNOW why it's 85 degrees out and you just spent 20 minutes at 5200rpm, but it sure could figure that into its oil change calculations. So if you spend July at the track, you may change the oil right after.

Given that the technology is easily implemented but that VW chose not to, I would think the 10K oil change interval as a flat number is overall conservative. I dunno.

May be difficult to get a VW recommended oil to use for an activity they don't endorse doing, ie; "racing".

As far as the maintenance minder goes, BMW used an algorithm a while back that did just that. They have streamlined it now to use one that is heavily weighted to gallons of fuel used. When you think about it, fuel use corresponds very closely to how/where/when the vehicle is operated and is the way I used to determine my intervals. Use XXX gals. of fuel, time to change the oil. I did this in conjunction with oil analysis to get close to the point where the oil needed changing. Worked pretty well and was fairly accurate.

10k OCI report at 20K miles on my GSW TDI. Stoked. She's got a slippery engine:

An open secret on BITOG is that it's less the type of oil you use (within reason) and more that you're regular with changes.

Use a 502 oil, and change when you feel is right. 5-7.5k if you're doing 90% short trips, longer if you have a more rounded routine.
