Hello 991 Enthusiasts,
I wanted to drop a line and say "hello" and let you know that we now have been a sponsor of Rennlist for about 30 days now. We started posting in the 993 and 997 forums and have had some great feedback and dialog there. We'd love to continue the dialog here with the late model crowd such as the 991 as we have full coverage of the Porsche brand with OEM approved oils. Motul 8100 oil's (and others) are a legitimate alternative to the OEM recommended oil and have a great amount of upside in comparison. Would love to hear your questions or how we can help your 911 perform even better. -Nick

 

Hello there,
Sorry must have missed that, there were many requests and replies to those threads. I won't post internal formulation data on the Internet but more than happy to analyze, confirm, deny the results of publicly posted VOA's. I have some I can work off of as well- can you provide what product you were looking for? -Nick

 

 

Hello,
RBF 600 is alive and well- it is our top selling brake fluid to this day. 660 is just a slightly better performing product but comes at nearly 2x the price, that is why the RBF600 continues to be the leader here at Motul.-Nick

 

Hello,
That is correct. The 2 products you mentioned are approved by Porsche for the 991- we also have a 3rd product called 8100 X-clean 5W40. We developed both products due to pure market demand of a 5W40 and 0W40. With the X-max 0W40 you only gain increased pumpability at cold start vs the X-cess 5W40. The formulations themselves are quite similar in terms of base oil formulation and ad pack design. Generally speaking, a 0W vs 5W at cold start will have improved cold oil performance so in theory less engine wear will occur and better fuel mileage. Either product will perform admirably in the 991 or any water cooled Porsche requiring the Porsche A40 profile. The 8100 line that the X-cess and X-max are apart of, are 100% synthetic products with a pretty stout additive package and while both are "service" products due to being OEM approved etc, both can certainly be used in a track dedicated car or everyday driver. That is the beauty of the 8100 line, good enough for the street and race track.

Our 300V line is our motorsport dedicated product based on group 5 ester based technology- Motul was the first company to develop a ester based synthetic for 4 stroke engines in 1971. For decades of continuous research, this product is unchallenged at the track to this day. We really are the only company that makes a true group 5 based engine oil- group 5's are not based on crude and are made up of up to 5000 different ingredients for a specific purpose. In our case, make as much power as possible while also increasing reliability. Besides being heavily friction modified to create more power, the ester base oils also have what is known as a "lower traction coefficient" vs group 3 and 4 synthetics that provide additional power making capabilities. Also, the ester synthetic oil film is virtually unbreakable so 300V's viscosity retention is second to none. This is how we can create more power while also increasing reliability. We tested 300V 0W40 (Oil 1) vs M1 0W40 and made 6.8HP and 1.2% more TQ on a 3.6L Porsche Cup engine last year- this was on an engine dyno in a controlled environment. You can see where the esters really begin to shine, at the top end of the RPM range where friction is at its highest:




To put it in perspective, the entire LMP2 class in WEC and Le Mans uses 300V right off the shelf as well as McLaren's entire GT3/GT4 program (also RBF 660 and Gear 300 oil). These are not paid endorsements but true technical partnerships. We have many reports from Porsche 300V users of 10-15 F drops in oil temps as well since switching to this product; also extending the life of their oil drains on their track cars. It is not Porsche approved as it is a track dedicated product but has all the detergents and traditional cleaning power of a service oil and is suitable for everyday street use. We just recommend sticking to a more conservative drain of around 5000 miles for street cars. Hope this info helps.-Nick

 

Hello,
Assuming your car is still under warranty a Porsche approved product will be necessary. If you're looking for an upgrade over the factory product, look to the 8100 X-cess 5W40 or 8100 X-max 0W40. Both are recommended for street and track use. These oils (any OEM approved product) do have their limitations vs 300V as they all have to fit a certain formulation window to achieve the Porsche A40 approval and others. That being said, they are both 100% synthetic and have very low volatility performance vs the OEM product so you should see less oil evaporation- an oil's tendency to thicken when exposed to repeated extreme temps- and a very strong oil film that is less prone to shearing- when oil viscosity is reduced. This will also increase additive retention- an oil's ability to retain the additive package in the oil. So at the end of the oil drain interval you will have an oil that was able to stay in grade longer, that cleaned and protected better. -Nick

PS- All Lordco locations stock Motul in BC as far as I know.
