I'm currently using liqui moly leichtlauf 5w40. Recently found out it's nothing but a glorified Group III oil. In fact it's not even full synthetic. The Red Line oil is a mix of Group IV PAO and Group V Ester. It should have far better stability and cold start protection.
i use red line 5w50 and like it a lot. engine seems to run smoother -maybe the zddp in the oil and it seems to hold up well to abuse. it's api/sn and not api/sp, which matters to some. i'm no oil guru and it seems like a lot of far more knowledgeable mechanics and racers trust red line. i plan to continue using red line. i feel more confident about red line vs anything else on the market. i use motul in motorcycles.
RL looks like a smart upgrade over the limits of MB-Approval limits. It's a great selection!
You'll enjoy the solid viscosity that is based on true stock viscosity instead of short lived polymers additives.
The combination of high heat point and ZDDP in this oil is a great upgrade for turbo sport applications.
Practically this means this oil will not degrade rapidly. It will work like new with the same solid specs hot or cold and for longer mileage, according to how much heat you give it.
By not easily being vaporized by rings, it will clean your pistons carboned rings.
You'll notice your cylinders seal gradually improving over 10kMi and ECU tuning richer mixtures.
The high heat in GDI engines is best suited for PAO. Group III does not handle the heat as well. It gums up to unbalance contributions.
This Redline PAO API-SN is gonna put a smile on face with solid protection. It is a Chevron-Phillips product. California lubricant
Did you feel loss of hp at high rpm? RL 5w50 is really thick. 20 for vis@100.
though in no way scientific and i've only used for less 1k miles, not only did i feel no loss in hp wtih 5w50, i feel like the vehicles are more responsive and seem to run smoother. i feel more confident driving hard and, i do occasionally hit the governor. it feels like engine is working less at high rpm. smooth and snappy comes to mind. maybe thicker oil creates feeling of smoothness. what ever the reason, i like it and i feel confident with red line oil.

+1: exactly!
The smoothness comes from balanced cylinders. ECU works extremely well with that. The opposite increasingly detunes contributions with losses. The difference is hard to ignore.
Run W40 PAO for a while to begin cleaning your cooled rings (10k) until you decide to step up or gradually blend. That's what I did. ✌️
You can blend a RL 5W40 SN with RL 5W50 SN and not loose any sleep over it: matching SN formula!
That what they call "Euro oil"... it quickly saves more gas.
Liqui Moly oil, at least in the US market, is all jokes. All their engine oil are Group III base oil except for Synthoil Energy. But even the Synthoil Energy is a very outdated formula.
If cost is a constraint, I would go to Walmart and buy the Mobil 1 Extended Performance. Solid Group IV PAO oil.
I hope I learned the Liqui Moly marketing BS earlier

Mobil 1 Extended Performance PAO does not seem available in W50... that would be great! Mobil makes Amsoil PAO stock! They do have PAO.
The marketing is so confusing it's hard to know what's what... One thing I know is PAO oils are not called synthetic because that's used for group-3.

Synthetic or full-synthetic are basic group-3.
In Europe, you can't call it full-synthetic if it has anything other than group iv and group v. In US, you can call olive oil full-synthetic thanks to the judge in the lawsuit between Mobil and Castrol.
5w50. I recently had my bearings apart after about 13k of 1k hp abuse . And actually looking at the bearings . They looked fantastic. . And amsoil signature series is full synthetic

The 5w50 usage is a new development. I'm not gonna go out and recommend it outright but nothing about the bearing clearances on an MB would tell me its a huge red flag. So how 5w50 works is it's a 5 weight cold, but there are additives/visocity modifiers that make it behave LIKE a 50wt at operating temp. These modifiers do eventually break down and you eventually get a thinner oil, followed by a breakdown/thickening of the oil near the end of its life which makes the first number go up so eventually you end up with like a 5w30 at the end of the day. It's part of the extended life of european-spec oils.
The 5w40 FS euro oils have been excellent in my use and I very much recommend them. There is the 0w40 Signature Series if you wanna do your own science experiments too. The 100% synthetic formulation is something you will feel on the first startup. It pulls a ton of heat out of the engine, start up quicker than it ever has cold, and it'll run pretty quiet when hot. I'm not allowed to PAY for your oil by corporate otherwise I would pretty much start buying everybodys oil changes here just to make a point.
mechanically both benzs are stock. in the past month, i added weistec tune to 2015 g550. i've used redline for 2+ years and been pleased with it.
before redline, i used do 3k miles oil changes, and, with redline, oil looked great after 3k miles that i've extended oil changes to 5k miles, which offsets some of additional cost of redline. i plan to also switch motorcycles to redline.
