Oil Type for 2021 SQ5

[AutoRacer100]

Hi All,

I have done an oil change with Liquid Molly. It seems the engine started burning oil more. My first oil change was OEM oil. It wasn't as bad as with Liquid Molly in terms engine burning oil. I know Motul oil is the way to go.

The factory recommended 0w-20 for my car. Can I use 5w-20 to increase the thickness of the oil for my car? I assume that would protect the engine better. Is there 5w-20 508/509 oil avaiable?

[383vett]

How much oil are you burning? Maybe bring it to the attention of the dealer so the situation can be documented.

[Smac770]

508 00 only exists as 0w20, that I know of. Just use what the engine was designed around.

Lots of good reading in the B9 S4 forum. Over there and other forums the consensus starting to form that especially for extreme tunes and bigger turbo's that VW 504 5w-30 oil (What is specified for the RS5 2.9 EA839 motor) is good to use at least in Summer.
Tuner folks are seeing less wear almost none from the timing chains and variable valve timing sprockets with 5w-30 versus 0w20. And that is the only wear item so far and you will see metal sparkles from that in your filter. Much more important if drag racing at a track and/or driving like a gorilla on the road.
Haven't gone the VW 504 5w-30 way yet, but thinking for my next change in the Spring. More piece of mind if I want to drive more enthusiastically. Just did a 5K interval 0w-20 change this week and tore apart the oil filter and found no sparkles.
Always a good idea to examine your oil filter with a bright light and some type of magnification. May catch something while it is still fixable. Most often metal shows up way before there are any noises.
Also haven't used any oil since new and now @ 20K miles.

[DiscoDan]

I'm running Liqui Moly and have zero issue with any burning. Since VAG recommends it you should have zero concerns

[4TBBUCS]

May just be me, but I run Audi’s OE oil. Seems to be the cheapest of the bunch, in my area anyway 👍🏼

[Hostile]

I’ve done one oil change so far, I went with OE because it was cheaper than Liqui-Moly.

I do use LM in my wife’s car, have to change it tomorrow actually.

I usually order my oil change kits from ShopDap, FCP, ECS or NGP.

[rcprato]

I do most of my own oil changes and for a few years now been using the Ravenol oil specific for my VW/Audi and have been satisfied with it but this morning I went to Blauparts.com to order up an oil change kit for my 18 SQ5 and price seems to have jumped a lot, $159.95 https://www.blauparts.com/audi-sq5-m...vw-508-00.html
Going to give the Liqui Moly 0W-20 Top Tec 6200 Engine Oil a try, FCPEuro has a similar kit for $112.63 and there is a 5% promo on their site now.

I wonder what Audi Dealer is charging for an oil change for SQ5 now?

That does seem expensive. I've been reading with interest threads on Bob is the oil guy forums and many people think 5w-30 504 is appropriate as it is used for the 2.9L EA839 and there are no differences in tolerances between the engines. I can get a generic brand vw 504 (rebottled Shell Helix) for about $60 CAD per 5L jug, making the total oil + filter expense only about $100 CAD ($75 USD).

[rcprato]

@TheContrarian thanks for the info, I may consider that spec for future oil changes.

0W-20/509 is not recommended but required as stated all over - from the vehicle itself to the various manuals.

IMO/IME it's a huge mistake using anything else as oil viscosity affects many engine design aspects - from oil pump(s) to oil passages to bearing clearances to piston rings (meaning, thicker oil absolutely does not guarantee better protection).

[burnman]

I found my 2018 SQ5 has used a very small amount of oil since new. I do 8000km oil changes and it uses about a half a liter during that interval. Maybe it’s just the nature of the beast.

508 is the certification for petrol applications, 509 is the certification for diesel applications, but I don't know of any "just 508" or "just 509" oils, all the approved ones are 508/509.

And the clearance and pump aspects are why it seems feasible to run the 504 spec on both engines. EA839 3.0T and 2.9T have the same clearances, at least in the workshop manual, for main bearing and conrod bearing checking. And the same oil pump, and thus oil pump sprocket. One of the differences between the 502 using EA888 evo and 508 using EA888 b-cycle is the b-cycle runs the pump 9% faster with a less teeth sprocket. This does not appear to be the case for EA839. Also, the 2.9T originally ran 502, so 504 is already a half way point between the original 2.9T and 3.0T specs.

Audi's agenda with 508 is strictly about better mpg, aka lower emissions taxes for them. That's not a bad agenda, but not something the individual owner needs to necessarily align to. 504 is an ACEA C3 oil, 508 is an ACEA C5 oil. https://www.valvolineglobal.com/en-e...pecifications/

You're inferring from a disparate mishmash of applications, attributes, specifications and inferences and as such I see nothing other than significant risk with zero upside of not using the factory-specified oil in your vehicle.

Great info! I compromised last oil change in March with 4 quarts 504 5w-30 and the balance (3.7 quarts) 508 0w-20. Still no metal in the oil filter, Still no consumption from 0w-20 only up until then. Maybe slightly quieter at idle, was never noisy anyway. Gas mileage always very good and seemingly the same. I liked the idea of still having green tinted oil while under warranty and it is green even diluted with natural no dye 504.

Are you using the factory specified ECU calibration right now?

Jesus, no. I've got ~15,000 miles on the APR stage 1 91 octane tune and I beat on it - some 250 launches and counting!

[amw896]

Mine burns a bit on the OEM oil but none when I switch to liquid moly....I like the liqu moly better overall

I agree with reasoning above that if an oil is VW approved for 2.9T the only downside running in 3.0T is reduced MPG but I doubt any of us will notice a difference.

I’m in need of an oil change and you have a very convincing argument…

Or just run the oil that Audi recommends…

I do like the blue color of the VW 508 oil!

[burnman]

I use Amsoil 0-20 VW508 approved oil. Everything runs smoothly and I get excellent gas mileage and performance. I change it every 8000 Km.

It’s Green!!

[AutoRacer100]

I just saw another thread that someone mentioned about switching the motor oil from 0w-20 to 5w-40. Will that move void the factory warranty? The thicker oil means worse fuel efficiency.

Why aren’t you asking the person who said that in the other thread?

[S4'ed]

Amsoil is not an approved 508 oil. Amsoil may say it meets the 508 spec, but it has not been independently tested and certified to meet the 508 requirement. I am not saying it is a bad oil, but it is not VW/Audi approved, which counts for warrantee purposes.

My '23 RS5 w/0W30 runs so much quieter than my '21 SQ5 w/0W20. On the next OCI, I'm going to put the same oil in the SQ5 that I just dumped in the RS5 - Ravenol VSW 0W30.

Speaking of oil, since both my '23 RS5 and '21 SQ5 have oil filters mounted on the top of the engine, I'm going to finally invest in an oil extractor. Since both the 2.9T & 3.0T require almost 8 qts, I'm going with the Bavarian Autoworks Fluid Extractor (10-qt capacity), on-sale now through ECS Tuning:

For those of you who have already tuned (blown your warranty), I remain fond of the Castrol Edge 0W60. It was spec for my BMW E39 M5 (miss that car). Castrol advertises it for racing vehicles, but who knows. Whatever you run, consider used oil analysis. They can help pick viscosities and change intervals. I've had a good experience with Blackstone in the past.
