Going to be helping my friend with an oil change on his 2015 GTI (fully stock) and he wasn't sure which oil to use - should I just grab ESP 0W-30 for the VW 502?
Oil Selection for 2015 GTI?

ESP does not have VW 502 00 approval.
Does the owners manual give any sort of indication of what to use?
Oops, got it mixed up with 504 in my head. The owner's manual says either a 5W-30 or 5W-40 that meets either 502, 503, or 504.
ESP is a good choice as is any Euro 40-grade at Walmart.
Just grab a jug (well 2 jugs for the GTI with some leftover) of Mobil 1 FS 0W-40 from Walmart @ $25 a jug. Or maybe grab several if you believe those that say the price gonna double

. /threadM1 0w40 FS or ESP 0w30 are both great options. 504 oils are totally acceptable in the US, per service manual. My local dealer does bulk 504 0w30 for most cars that don't require 508 or 507.
ESP won't prevent carbon buildup so I generally use 0w40 FS since it's been proven in many high power EA888s in friends' Mk7s and is a few dollars cheaper per change where I am.
My local dealer used 504 00 instead of 508 00 per my request during the free oil changes. I have a small suspicion they do that all the time but I don't know it for sure.
I hadn't heard about the difference in carbon accumulation, is it a difference in hard carbon deposits on pistons and in ring grooves?
The low/mid-SAPS VW approvals require (504 definitely does, we assume the others do) a ceiling on intake valve buildup by mass. It also adds requirements on piston cleanliness but in my experience seeing the insides of a bunch of EA888s, the ones on 0w40 FS (502) are also pretty spotless and a really good 502 can meet or exceed the performance of a 504.

Intake valves. There was Lubrizol study about it. But it is controversial. I used in 2011 Tiguan 502 and 504.
Forgive my ignorance, but wouldn't ESP meeting the requirements of 504 00 mean that it complies with the intake valve deposit limit? Or have you generally found that the FS 0W-40 engines have cleaner valves despite the different specifications?
yes, it does meet the limit. it is one of the best approvals to look for.
however it does not prevent buildup entirely. I wouldn't claim to have witnessed a difference in valve buildup, but that's a factor of everyone I know who's torn down or scoped one was running port injection and beating on it (so the port injectors were actually activating regularly). I should post one of my factory pistons sometime (mostly ran M1 0w40/5w40), they were scuffed from DI failure but rings were great.
you can shop data sheets if you want (Noack, SAPS %) but long term you will need to walnut blast and replace PCVs on that engine as maintenance, oil won't fully prevent it.

Run Mobil 1 ESP 0W30. It has esters in it, it has same Noack as 0W40, and 0W40 does not have measurably higher HTHS, but does have much higher KV100, which indicates need to bump KV100 to get acceptable HTHS.
WHile Mobil1 0W40 is exceptional oil, I think latest version is bit diluted comapred to previous ones. If you want 40 grade, go Mobil1 ESP 0W40 X4, or Pennzoil Platinum Euro 5W40 (VW502.00).
Tell your friend to change oil and filter much earlier than 10K, most do 5K to help mitigate IVD (intake valve deposits), sticky rings (thanks low tension), and timing chain stretch (due to soot from longer OCIs). The oil in and of itself will not magically make these issues go away, it is the inherent design of the engine, breather system, DI, fuel dilution, seal issues etc. that are the culprits. Old, worn out oil doesn't help though. If you DO start with a decent oil as all have suggested, do preventative maintenance on weak parts (PCV/breather/oil separator will spare an expensive RMS replacement), and change it often enough, you push those inevitable problems to address even further down the road. Oh, and tell him/her to drive the piss out of it, it's a really fun car to do that in.
I would agree that 0w30 ESP is fine, but I wouldn't recommend ESP 0w40 or PPE 5w40 now, pricing and supply have become much worse. Autozone stopped doing the 5qt + filter bundle for 0w40 ESP here and PPE 5w40 completely sold out locally a month ago--online prices are approaching 2x the cost of 0w30ESP/0w40FS.

Didn’t catch up on prices. AAP had sale of PPE 5W40 recently:
Yeah, I would just go ESP 0W30.
Yeah, I caught the same sale, that's why my local stores are all sold out
Still on clearance but only a few quarts available in my city, not worth the gas to go snag 1 or 2 from each store now. They were new bottles (SQ rated) and on clearance for $5/qt or so, I'm not sure why they're trying to wipe out stock in this situation, maybe artificially driving up the perceptions of a shortage to increase pricing on an inelastic good? Or just getting rid of the line entirely, who knows.

Scored 4 Mobil 1(s) today at Walmart. With my $10 per jug from the current Mobil 1 special, these were only $17.97. My $40 Mobil 1 gift card will go toward a single malt scotch for the 4th. Thanks Mobil 1...(I do like Valvoline XL-III however).

Who know, maybe new line up is coming. But I would be on a lookout for changes due to disruption of GTL supply.Yeah, I caught the same sale, that's why my local stores are all sold out
