Hello! Been awhile since I posted. Sold my C5 'vette to my neighbor and picked up a brand new tornado red VW GTI SE manual with those sweet 18 inch black wheels. Oil temps regularly around 220 degrees, +/- 5 degrees. Engine in vehicle is 2.0 TSI, and owner's manual basically states to use 0w-20 for better gas mileage. I wanna bump that up to 5w-30 or even 0w-40. Any recommendations in API SP flavor? I plan on draining the break-in oil at 1000 miles
 
I always say to use what the owner's manual calls for and allows. And depending on how hard you plan on pushing the engine(after proper run-in of course), is which oil grade & quality you should use. Living in AZ, and Spring/Summer approaching, you may want to choose wisely and no one knows this better than you. Again, how hard are you going to push the engine?

EDIT:
Pics please! 🙂
 
What does the sticker under the hood say? When I had a Passat 2.0T I deviated from VW508.00 as well but never confused the fact VW requires 0W-20 508 be used.
 
My 2019 Passat uses the 508 oil and I change it at 5000 mile intervals. At 13000 miles, it burns zero oil between changes and runs just fine. It is rare that the oil temps on this 2.0 liter engine see 212 (according to the internal digital readout) but instead hover around 205-207 with hiway driving. I would stay with the 508 oil while under warranty at least.
 
If you must add oil and no oil is available that meets the Volkswagen oil quality standard required for
your engine, you can add a maximum 0.5 liters (0.5 qt) of engine oil that meets the ACEA A3 /B4 and API
SN specification, and has a viscosity grade of SAE 0W-20.
Using oil with a different viscosity grade than SAE 0W-20 can cause the vehicle emissions and fuel
consumption to increase.
Only use different oils in cases of emergency.


Above if from my MK7 2019 owners manual.
Below is from erwin.vw.com


1.4L (DGXA / DJXA)
VW 508 00 (0W-20)
VW 504 001) (0W-30)
VW 502 001) (5W-40)


2.0L — (DKFA)
VW 508 00 (0W-20)
VW 504 001) (0W-30)
VW 502 001) (5W-40)

I am OK with fuel consumption and emissions. My southern climate doesn't require thin oil and nor does my extra 5psi of turbo boost.

Funny how VW pushes the 0w20 508/509 oils for the US market when the engine can use full sump of 504/502 anywhere else.....
 
Here are some top-notch 508/509 approved oils I'd run in GTI.

Thanks for putting that up. I probably should have quoted it. Judging from what the Lubrizol spider chart is showing, VW 508 is a very high standard. I'm still a bit worried about oil temperatures for a 0w-20 though. Boomer mentions his only going up to 212 rarely. Maybe because the way I drive. I'm not a slow driver lol, and it's getting hot outside again. Looks like I'll be looking for previous VW approved oils that are a grade up.

Funny how your warranty is based on the owner's manual located in the glovebox of the car when it was sold to you and not an overseas version. My choice to deviate would be based on this fact, understanding of course, the possibility of any oil related issue to be rare.
 
Since the OP mentioned SP, before people have him veer off with different weights, he needs to understand "what he is working with" WRT VW oil specs. I see no evidence of that; posts indicating to reference the OM is what we all should be doing @ this point JMO.
 
Just giving you some other grade choices.... 0w30 or 5w40.... since 5w30 and 0w40 aren't mentioned in erwin as an acceptable grade.

508 or 504 or 502 should be considered a must, except for that 1st pint top off.

I also don't care for the 10k mile interval and have never had an engine related failure under warranty. So, I don't need an engine warranty.... I need the bumper to bumper for the rest of the interior cheapness that the car is made out of and the electrical gremlins. I am glad that the 2019 had the 6 year warranty, otherwise wouldn't even consider VAG.

I don't use VAG filters either. Plenty of good aftermarket choices. There is a Fram on my 1.4T right now.

I see that Lubrizol has offended some 'specs' from others and needs to disclose that comparisons can only be used among a brand.... Lubrizol lawyers working hard to protect Lubrizol. 🤣

I am guessing that EVERY one of my future oil changes will be in cases of emergency!

And, SN is gone and replaced with SP.... will VW add an addendum to the manual?

I got one addendum from VW to my owners manual. Since maintenance is free for 2 years, they changed the brake fluid 1st interval to 3 years from 2 years, and then every 2 years after that 1st 3 year change.... Maintenance is great only when you can charge the consumer.
 
The motor in the golf is the gen 3 2.0 with an IS20 turbo. A few years back the Gti was specced with vw 502 oil. Now with fuel economy standards they specced the golf with the 20 weight. The golf R is still specced with the more stout oil. Run a euro spec oil with a hths of 3.5.
 
I am quite puzzled why some of you are giving advise to OP to go with higher grades or viscosity.
According to Infineum, today's lower viscosity oils such as 0W-20 508 are based on high quality base oils where final blend requires very low percentage content of VII known as viscosity modifiers which are less shear stable than base oil itself.
I'd say to OP, go with what's recommended and you'll be in good hands.

I looked at 0W-20 Ravenol VSE I mentioned above,
This oil has VI 182 which is higher than majority of 5W-30 oils.
The content of VII is only 1.4% compare to many 5w-30 oils which have 3.7%-7.1% content of VII.
This alone tells you that Ravenol needs less VII to bring it to final grade because it contains high quality base oil and therefore more shear stable.
