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?
