2019 GTI Requires 508 spec 0W-20 oil

[mindonmatter]

How do you know a specific oil meets 508? I used the Castrol so I know by tribal knowledge I guess and that VW told me to use it in my new car literature but other than, the Castrol bottle doesn't say meets or exceeds vw 508 like it does with a bunch of other makes...

Castrol makes 0w20 that's isn't 508.00 compliant, so maybe that's what you used? If it's 508, then it will say 508 on the back. This is what you want:

CASTROL EDGE PROFESSIONAL LL IV FE SYNTHETIC 0W-20

I most certainly did not use that oil. Shit. Just straight Castrol Edge 0W-20 from Autozone. It's funny how you can think you're so right and still be wrong. I never thought to look at the literature again to double check. I just remembered Castrol Edge 0W-20 and clung to that. Eh. I'm changing it again in 3,600 miles. Should be fine ha

Just found this. https://www.valvoline.com/en-austra.../synpower-synthetic-engine-oil-xl-iv-c5-0w-20

Leads me to believe we'll get more 508/509 approvals for other oils hopefully soon.

Do the 2019 say you must use VW 508 oil? Or is VW502/504 acceptable?

BMW says you can use LL-01 (5w-30/40) in lieu of FE14++ (0w-20) with no issue.

I hope that more companies producing the 508.00 0W20 oil will mean that the price will drop some. Also I hope that valvoline makes the 508.00 approved oil available in 5L containers not just 20L.

The manual says VW 508 00 0w20 and gives no alternatives.

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

My Wife's old 2007 Jeep wrangler called for 5W-20. Don't know what her new Grand Cherokee calls for yet. My Civic called for 5W-20... The SAE 20 doesn't really seem to be a new thing? I want 0W for start up. I want that oil flowing. So 0W-20 seems like its been a long time coming for VW. I'm sure its been in R&D for the last few years. I read somewhere that every engine start is the same wear as driving 300miles at normal operating temp due to the lack of oil flowing for that split second on start.

Just get your oil changed at the dealer when they run oil change specials until 0w-20 508 is readily available. Glad my 18 is still requiring 5w-40. So easy to find these for $12-15 a jug.

Walmart has Castrol Edge SAE 0W-20 Advanced Full Synthetic Fluid Titantium Technology 5qrts for $22, except it doesn't say VW 508, but i bet you all its exactly the same shit that they're selling to VW. minus the extra ink used to print VW508 spec on the back.

I’ll take that bet! I couldn’t find Castrol but here’s two 0w-20 oils from SOPUS(Pennzoil). Hint, they’re not the same.

Here's Castrol

Regular 0w20

508/509 0w20

The pour points are different, so the 508 stuff has a different basestock.
Viscosities are different also.

MSDS lists 508 stuff as having Group III & IV basestocks where the regular 0w20 is all Group III

Another way to look at the differences between an API SN+ oil and a ACEA C5(which 508 00 starts from) is in this chart:

^^ its all fair and well and thanks for the research, however they've not re-engineered the engine in any way. The EA888 from 2015-2018 ran fine on 5W-40 VW502, so its really not exactly going to make any real world difference, apart from satisfying some EPA bureaucrat going with 0w-20 vs 5w-40... And using Castol Edge vs Castrol Edge 508 isn't exactly going to grenade your engine either.

 

[DiscusInferno]

EPA estimates for the GTI... from 2018 to 2019, the mileage roughly stayed the same. Comparing estimates for 6MT, the 2019 with 508.00 got roughly 4% worse fuel economy, not the 4% improved fuel economy that 508.00 is supposed to give.

SN+ also addresses the phenomena of Low Speed Pre-Ignition on GDI engines, which when you do a VOA, you'll see that Calcium levels drop, in exchange for Magnesium level to rise.

It is thought that excessive Calcium sulfonate (that's the detergent), contributes to LPSI.

Agreed in all respects. If I owned a VAG that spec’d 508 I would research it(like you) and see what changes were made to any internally lubricated part from the oil pump to the journals. If there were no change I would find myself a readily available and cheap 502 or 504 oil and be happy.

The switch to low HTHS oils is because of emissions regulations, not wear. Most of the heat put into the engine oil is from the oil itself. If you keep a bearing in hydrodynamic lubrication you prevent wear but heat the oil. If you use up the oil film you are in boundary lubrication and wear the engine parts. The “mixed lubrication” zone is where you have the least friction. It relies on the additives like Mg, Ca, Ti to prevent metal to metal contact. Look at the Stribek Curve if you want to go down the rabbit hole.

I just don’t want someone to run and buy the cheapest 20 grade oil and run it 15k miles between changes. Or worse yet go to a quickee lube and get a bulk oil.
