2019 GTI Requires 508 spec 0W-20 oil

Picking up my 2019 GTI later this week. Reading this thread with extreme interest. Keep the comments coming.

Yeah, I've read all the way through that... But this is an oil thread and thats a 2019 stalling thread. Anyone with a 2018 or earlier mk7 have a good baseline operating oil temp on the 5w-30 or 5w-40? I have almost 1,400mi on the odo and the highest I've seen is 225F with an OAT 72F after a ~30mi trip from work starts with highway then ends with relatively frequent stoplights/signs. This is on 0W-20 Castrol Edge. If I'm seeing ~220F on 0W-20 and someone with 5W-30/40 is seeing 220F... I'd think the oil is doing it's job, preventing metal on metal? I dunno. Also, at 1,400mi my "extended period" mpg is 31.3... 31.3 and 220F on 0W-20... I would like to see other numbers people are seeing on both the 0W-20 and 5W-30/40 or hell 0W-40(which I personally think is probably the way to go).

Maybe in a couple of my posts in that thread, I did mention that I saw oil temp at ~230 with my earlier stalls. I frequently saw temps staying at around 225. These were on the hottest, muggiest days so far (90-92 F). Lately, I've noticed oil temp sits around 220-222, but it's been milder. Recent ~500 mile trip on the interstate, it stayed right about there.

I'm now at 1100 miles and planning to do my first oil change. I think I just feel safer sticking to the recommended oil for now, while I spend however long it will take, going forward, dealing with the stalling issue and getting a proper fix. I don't really want to give VW any sort of reason to deny a claim or diagnose as user error. ....to that end, I do need to bring it back to the service station because it has occurred about 5 more times after taking it to them the first time. So, I think I will also stick to dealer oil changes until that time (also, no real means to do it myself right now--though I'd like to get an extractor and get back into actual home car maintenance again....it's been a while).

Any idea if taking to a non-dealer "certified VW mechanic" would cause possible warranty issues, or is that even a thing that actually exists? I do have some more local guys that are VW specialists and are apparently doing warranty services, but I don't really know what that means, tbh. I'm not very convenient to a VW dealership/service station so was hoping I could stick to one of the nearby guys for routine stuff.

AFAIK, I don't get free oil changes and even so, if that means the dealership that I bought it from, that's a 60+ mile round trip, so no thanks.

Just gee whiz to add (and apologies if specifically mentioned, I don't recall the earlier parts) I had to add some to my 2019 yesterday. I double-checked the manual in case. It stated the 508 mentioned, but said if needed and the 508 is not available (which it didn't seem to be in the small town I was in) then you can top off with no more than 1/2 qt of VW 502/504 in the 5W-30/5W-40 viscosity (maybe 0W-40 as well, can't remember the last one). They made it sound dire in the manual, but the only side effect it said was that using the substitute would slightly affect gas mileage (manual actually says slightly).

If that is really all it could affect I don't see why they'd go on about only using a half quart with all bold lettering and warnings. TBH if I can use a 502/504 and get it locally for half the price using Mobil 1, Castrol Edge non-Pro, or whatever I have no problem losing 1MPG or so.

I need to have a chat with my local dealership to see what they're using. I'd rather go with a more durable option as well than worrying about 1-2 MPG and having to top it off more often.

Has anyone been able to confirm ANY changes to warrant use of 508 0W-20 vs. the formerly recommended 502 5W-40? Other than to fastidiously conform to warranty fear, is there any VALID reason to use it? Who is planning to be a rebel and use the 502, 0W-20 be damned?

I can't positively confirm but from comments from other more knowledgeable members, it seems the only real change in 2019 is the oil pump. So that might be the only issue, but it seems to work just fine with 502 for other owners. AFAIK, that is the only difference mechanically, but the ECU is also new for 2019. Could be that the related issues are just some oversight in the ECU not being coded to address the new pump and oil spec, so it's still expecting timing, pressure, measurements, whatever, that you would get with a 2018 and earlier engine on the 502 spec and the previous pump....that's my thinking, anyway. But I don't really know how any of this works.

When tuned, I think 502 is still required?

VW still goes with 502 for the 2019 R, according to the manual.

Oh, and I'm also up by several more stalls since my post last week. Up to 16 now (through yesterday), with basically 10 of those occurring in the last 2 weeks, so much higher frequency. I am confident that I can replicate it now, because I've been paying more attention and figured out to force it, mostly using the stall protocol recommended by another user (3/3 stalls on 2019 GTIs for him, so far tested). My specific reason for being fastidious with the oil spec, because of warranty, is simply because I have a legit issue and I don't want to give VW any reason to deny it because of actions that they did not perform.

I think VW service actually did replace the oil in one owner having stall issues with 502. But that didn't seem to fix their problem. In other cases, at least one owner seems to have done it themselves, and that seems to have stopped the stalls.

There is a new link in VWVortex, reposted in the stall thread here, about one owner that may have fixed his simply by pumping the clutch and brakes several times. He noticed that his clutch seemed to be catching and thought it was a hydraulics issue (I notice that my clutch is a bit slippery from time to time--it was suggested that this is related to that delay valve thingy that should really be removed...which I may indeed do, once the stall is fixed. ...or maybe that fixes it? Dunno. I get the feeling that a lot of owners with more experience probably do these quick modifications from the beginning, just because of familiarity, and so never experience this issue because somewhere within those mods, this problem lies and they have fixed it without knowing it, heh).

I was trying to buy a kit online for my 2019 gli. Nothing seems to be available for any of the 2019 stuff and Ed’s has 2 different oils. The 0w 20 and the 5 40 stuff. I don’t give a crap about the gas mileage, would rather have the thicker oil but it doesn’t sound like there is a consensus that it’s ok.

I’m assuming the 2019 fit and gli are using the same oil since the engine is the same. If going 0 20 what brand is recommended?

Take advantage of FCP's lifetime guarantee and they'll refund the cost of the oil after the next purchase and you shipping the used oil back to them.

Mobil 1[emoji769] Extended Performance is not approved for be 508/509 00 spec but compared the mobile 1 to the 508.00/509.00 spec it's pretty darn close. I think I'm will be fine with Mobil 1. I've been running Mobil 1[emoji769] Extended Performance since last month and have noticed anything different. Oil temp range from 215-227F same with Castrol from the factory. I planned to change every 5K miles. To use Mobil 1 will not put a dent in my pocket like Castrol. LOL

Mobil 1 has a 0w-20 that meets the 508 spec now:

Not sure on it’s availability yet though.

I put regular mobile 1 extended at 4K miles. It seems fine but I changed back to the factory Castrol 0w-20 508.00 at 5K and consider it my first oil changed LOL. I'll change the oil every 5K miles from now on. The car got 6 years/72K miles warranty. I don't want to running into a problem with warranty denial down the road. [emoji3]

Interestingly, the 2019 Golf R still uses 5w30 or 5w40.

Or 0W30 or 0W40 (I am currently running M1 ESP 0W30 in our 18 R)

Dealer switched my 2019 Rabbit 6spd MT to 5w-40 due to rough dle, poor driveability, and terrible gas mileage issues that destroyed the O2 sensor in 600 miles. Car has run perfect since switching to 5w-40. Dealer said there's a bulletin out there for the 2019 MT cars, but no one has seen it. They also claimed manuals would be going back to old oil spec for 2020.

I can't confirm this through any official means, it's what my dealer is telling me. They said they've seen 3 2019's running the same easy and destroy the O2 sensor and switching oil back resolved the issues with all 3 cars.

Manual cars are supposedly getting an ECU update at some point too, due to the stalling issue.

My 2019 Black Rabbit 6spd has no issue with 0W-20 VW 509.00. I asked the service advisor at the dealer in Virginia about using different weight oil. He said if you are using anything different from what the manual said might void your warranty.

Lol, that's pretty funny. VW didn't change the engine and would have to provide some rational, that doesn't exist, for voiding the warranty over oil weight, especially since the R still uses 5w-30 and 5w-40. Your dealer staff are idiots.

And what's your point? If your car isn't having issues, why would you ask to charge the oil to fix a problem your car doesn't have? Or are you implying that since your car doesn't have an issue, my car wasn't really getting 26 mpg on the highway and didn't destroy an O2 sensor in 1200 miles?

Try reading. Dealer changed the oil to fix my issues based on a tech bulletin.
