Hello,
The 201 is a conventional gear oil. Pretty standard stuff- lots of EP protection but pretty low performance in terms of gear oils as a whole. With a VI of only 107, this product will fall out grade very quickly as temps change or any demand is placed on the product.
If you consider our Gear 300 LS 75W90, it has a VI of 161 so a much higher performance level while retaining its viscosity. It is also a GL-5 gear oil like the 201 so it has outstanding extreme pressure protection as well. Also, it is based on group 5 esters- there many performance advantages of ester synthetics vs even traditional group 3 and 4 syns. For gear oils, oil film strength is a key factor. Group 5 esters have basically an unbreakable oil film so you’ll see much more consistent performance and better protection from Gear 300 vs the 201. This product comes turn key and has all the necessary friction modifiers for LSD applications. The 75W140 version of this oil is used by McLaren’s entire GT3 program by the way. -Nick

Motul has always sponsored racing, i have gotten several liters of Motul over the years for free from Motul, thanks. In a previous life i worked for a company called symyx we had a $500m program to develop combi chem discovery platforms for exxon. I worked on the oil discovery program and helped to developed a blending platform to go from gallons to 500ml vials blending hundreds of variations in hours. Go to Motul when you see them at the track and ask techical question and you will get very informed and very technical info, so the same with royal purple and you will get marketing. Very few oil companies do more than buy base stock, buy blending packages, and do a bunch of marketing. Motul is honestly one of very few that have the technical expertice, equipment and dollars to support true engineering. Even fewer give access and support to those expert like Motul, Thanks Motul!

Not really a Porsche specific but I thought I can ask. What oil would you recommend for '93 Mercedes Benz W124 500E with 5 liter V8 engine? It was recently rebuilt, all new gaskets, heads refreshed etc. It's currently filled with 10W40 semi synthetic oil but I think I could go with full synthetic. Where I live summers are pretty mild and car won't see real winter due to salt on the roads - 5W40 would be perfect?

Not a problem. This engine required a Mercedes 229.1 approval so as long as the oil you choose has 229.1, 229.3 or the latest- 229.5 approval, you’ll have an oil that either met the spec or has superseded it since. 229.1 being the oldest of the 3.
So here is a breakdown of oils that are formally approved for this application:
Motul 4100 Power 15W50: 229.1 approved
Motul 6100 Synergie+ 10W40: 229.3 approved
Motul 8100 X-cess 5W40: 229.5 approved
The 5W40 will definitely be the most universal oil for different ambient temps (cold/hot). If the cold isn’t a concern and the summers are mild, the 6100 10W40 would be my choice for this application. The 6100 is our standard synthetic product where our 8100 is our flagship-high-performance service/race product and is 100% synthetic. -Nick

Thank Nick for your reply. I did some research too and found out that 8100 X-cess might be the best choice. It also has a very affordable price here. Just one concern - on a hot day oil pressure, especially during idling, won't be lower when using 5W40 compared to 10W40? Apologies if it's dumb question...

No, they are both SAE 40's at operating temperature so the viscosity and oil PSI will be the same at higher temps. You may see lower oil PSI during start up as the 5W vs 10W will have a lower viscosity. In exchange you'll be getting better oil FLOW at startup, which is actually more important than oil PSI (within reason).-Nick
