LiquiMoly Synthoil Premium 5W-40 or recommended Castrol Edge

[esemett]

Another engine oil thread... get ready guys...

Recently changed the oil on my 2015 S3. I like to change the oil myself, and I decided to try LiquiMoly Synthoil Premium 5W-40 since I've heard good things about it and my local NAPA carries it. Is this specific version of LiquiMoly any better or worse than Castrol Edge 5W-40? Are they category IV or III oils? Has anyone used this specific version of LiquiMoly in their S3?

This is my first German car, and I've had an Evo and a 350Z before that where I used Eneos 5W-30, which I thought was a great oil.

Thats a great choice run the same LiquiMoly stuff in my RS4. Some will debate but its way better than Castrol.

Motul

LiquiMoly.

I did not use Liqui Moly engine oil yet but I have read only positive reviews posted by those who did. The only Liqui Moly product I used is Ceratec Oil Additive sold for like $25. I did add a bottle of this additive right after the dealer did its 15K service. A few days ago I checked the oil level on the dipstick (to see if the engine consumes any oil) and I was pleasantly surprised to see that the oil remained at the same level as the one noted right after the service and it did not get discolored (it has been around 3K miles since the last oil change and the oil should be darker by now). It looks like the service was done last week, not as it actually happened i.e. three months ago. I know the oil discoloration does not necessarily mean it lost its ability to properly lubricate nevertheless it still is one of the parameters. My naïve optimism tells me that the Ceratec Additive did in fact created an additional protective layer preventing any metal to metal contact thus significantly reducing the wear.

I normally use the Motul oil service kit I buy from from ecstuning. This one https://www.ecstuning.com/Audi-8V_S3...ice/ES2777506/
All I can say it is fantastic engine oil. Either way, Liqui Moly or Motul, they offer more protection under extreme conditions than the factory recommended Castrol Edge.

Both are group III oils but that doesn't mean anything. The Synthoil Premium only meets old BMW and Mercedes oil specs. Head over to Walmart and pick up either Castrol Edge 0W-40 or Mobil 1 0W-40. Both of these oils meet the latest Euro oil specs like Mercedes 229.5 and BMW LL-01. The VW 502 spec is pretty easy to meet compared to the other two I mentioned.

For $10 more per oil change, why wouldn't you spring for the marginal cost of the better quality Liqui Moly/Motul? Especially if you plan on tuning and/or keeping the car around a while...Motul fan here.

I bought the car used from a BMW dealer who decided to put 5W-30...

Either way, I would prefer to stay to the factory spec. No 0W-40 or anything for me.

I want this car to last.

This kit comes with 6 liters. Don't you need quarts for an oil change? Also why does it come with plastic oil plugs? Don't you have to suck the oil out?

You don't have yo use the extractor. I just drained it from the bottom like I always have. I re-used my plastic bolt, just be careful, that's all.

Why do you think those two are better oils? Is it because they are come from France and Germany? The two oils I have mentioned are proven to be the highest quality 40 weight oils on the market. I have seen hundreds of used oil analysis and the Mobil 1 and Castrol Edge show great results.

For the op. What 5W-30 oil did this BMW dealer use? I would use a 0W-40 oil if I lived in Chicago. It would help for cold weather start ups.

the BMW dealer was super vague about it, I asked one of their Service Reps(a woman) and she said they used the spec that is for the car. She refused to tell me what kind of oil specifically it was, only that it was put in as 5W-30 in their notes. Needless to say, I changed the oil a few weeks later.

I've got Liqui Moly ready to go for my 10K oil change and an oil extractor.

Purol 10w40.
You want the best, you have to pay for it.

First time using Liqui Molly Leichtlauf High Tech 5W-40, I did used Motul in the past , I don't know if it is just me but after doing the oil change I felt my engine it's running like on a 10w40 (Due to Cstrol 5w40 lower drag resistance the engine runs easier). Summer coming so it is fine but next spring I will be going back using oem oil or maybe use Liqui Molly 0w40 . I am not saying Liqui Molly it is bad as I believe it is better than Castrol , but since I don't mind doing oil change more often I rather use Castol . Otherwise , I will choose Liqui Molly or Motul .

Also , if anyone is trying to decide which Liqui Molly will be more appropriate to use for Audi gas engine , this is Liqui Molly recommendation : "both oils would be possible to use in your engine. Our recommendation would be to go for our Leichtlauf High Tech 5W-40. This oil is an state of the art engine oil for petrol engines. The Top Tec 4100 5W-40 was first of all developed for diesel engines which are equiped with a particulate filter system. Further more the Leichtlauf High Tech is more suitable for countrys with a low fuel quality."

This is the Liqui Moly I use. Also, I use their Ceratec Oil Additive as well.

Liqui Moly or Motul over Castrol or M1.

Doesn't the S3 direct injection engine require VW 504? I know the V8 DI engines do, that's the spec for my 2010 S5. A VW 502 spec is inferior, but the 504 spec is equal or better to either of the BMW LL03 or Mercedes 229.5 specs.

OK, I just did a quick internet search, and the actual oil spec for the current S3 was VW 504, so I'd only use a VW 504 spec oil...

Chiming in....

The oil spec of VW 502 00 is clearly printed under the hood. Not planning to mod or track. I do the "in between" changes leveraging the VW branded oil as the dealership is literally a minutes walk from me.
I may switch over to Motul or Liquimoly once I hit higher mileage.

So much debate over what oil to use however it is an interesting topic to say the least.

Tons of information over here

+1 on Bob is the Oil Guy, the subject definitely gets beaten to death. I'm on 70k with my 15 S3. Based on the information from BITOG, I've run both the Liqui-moly and now Redline. From the HTHS numbers, it being a Group IV oil, and it holding 502 rating, the current Redline 0W40 technically seems to be one of the best oils out there for our application. I love it, having sent two batches off to Blackstone and felt the power increase in the butt dyno, I'm hooked on the stuff. Sucks how much it costs though. I justify it by getting a MityVac oil evacuator and buying the redline by the case at a local dealer(for the best price).

Redline did mention that their additive packages are fully active at 175f(This is true of most oils), so I don't load the engine up until I see that temp. Only issues I've had were a failed waterpump(warrantied), and a leaky PCV($100 and 15 minutes to change) in 70k+ miles. I've been stage 2 since about two weeks of purchasing, and stage 2+ after a month.

Butt dyno...are kidding me...that's a joke right?

My piece of advice, don't take advice from someone who says they can feel a difference in their butt dyno from a different oil of roughly the same weight.

FYI...redline is garbage.

Believe or not ,it matters. If you know you car good enough you will notice the difference . I seen it with Motul vs Castrol on a mk2 tt 3.2 and now on s6 using Liqui Molly vs Castrol . As a matter of fact I just did the oil change today after not even 500km on Liqui Molly! This was my shortest ever oil change From now on I will only stick with Castrol and oil change done on Spring and Autumn . Maybe I will use Mobil 0w40 for winter as it have better viscosity index (Castrol 0w40 -168 vs Mobil 0w40 -186)

Nope, I'm not kidding you. I know a lot of people who can tell a difference in power after fresh oil?

Who said anything about differences in power between brands? No idea what that's like cause I would have to test both oils back to back while fresh... and personally, i never fill up with one brand, and dump it right away to test what it's like..

Can you cite some sources on how RedLine is garbage? My only problem is that a lot technically inclined people seem to disagree with you on Bob is the Oil guy. Also, I was speaking specifically to the new 0w40 they use, which is a Group IV, VW Approved oil.. not garbage.

Same?

[Sport Line]

Like I mentioned , I felt difference some years ago when changing from Castrol 5w40 to Motul 5w40 ,but back then I did not made such a big deal of it.

Now , I noticed the same difference from Castrol to Liquid Molly , same 5w40 . I know my car pretty well and my driving habits remain the same , there are at least a few stop lights on my way to work where I usually wot pretty much every time. So exactly the same dry conditions ,sport mode,esp off , I noticed there was no more tires spinning when doing so (there was not much before but enough to notice there is ) . Also , I could fell a little difference on other gears as well , it just did not pulled the same. I am not saying the car lost power , as if you will dyno there will probably be no difference since dyno acceleration it is done gradually, but when wot it feels like there is less tq available . Anyways , back to Castrol after a few weeks on Liquid Molly and things are back to normal . 17 April 2017 Fist oil change 59300km , second oil change May 1 at 59,930km . For decay guy ,maybe you should first DYI and after come with some real feedback

And yet across thr board casrtol is some of the worst oil out there.

So the car would show signs of power loss on a dyno, the instrument used to show power, but you can feel it...lmao. whatever dude, go back to your digital abd butt dyno racing.

Clever...lol, please note the heavy underlying sarcasm.

But I'll give you a participation "A" award for your attempt at an insult towards me. Keep on trying, they say practice makes perfect...so maybe you'll get there at some point. Likely not, but you'll believe you have...simialr to you being able to feel power loss or gain with a different type of oil at the same weight.

I am not here to insult anyone and it is not my goal to get better at . There are plenty of youtube videos with comparison of different types of oils at the same weight and you can start gathering info right there if you don't want to DYI . All those brands I mention have different viscosity index and based on this info only you should expect some variations . I am not saying there is a night and day difference but for me it was enough to dislike using one vs another. If I would wanted a long term using oil yes I would probably kept liqui molly or Motul but that's not the case. Aways , you have your opinion , I have mine.

Cheers!
