WHB Porsche

Everyone should see the last three pages of this thread over on the 993 board: https://rennlist.com/forums/showthre...407224&page=17

Pay attention to Charles Navarro and Steve Weiner. I just ordered some Swepco 15w-40 to try.

Spartan

Yep Swepco or Brad Penn ftw

Kevin

Swepco and Brad Penn are good oil but are NOT Porsche approved. Nor would I run them in a turbo air-cooled engine. Run Mobil 1 Delvac full synthetic or Mobil 1 VTwin, if you want a better "approved" oil run Motul V300. BTW the Mobil still sell 5W50 in Canada thru Canadian Tire..

Spartan

Why wouldn't you run them in a Turbo motor? Also doesn't an oil have to apply to be approved by Porsche? I have no idea just curious

Kevin

You need to run a synthetic ester base oil. The companies that don't > don't want to spend the money for approval and testing. The dino oils don't have the high temp stability. Go to Mobil 1 website and look up the VTwin spec data..

Hi,
Kevin - I agree with you regarding a lubricant's formulation and the use of complex esters. Both M1 0w-40 and M1 TDT 5w-40 (and Delvac 1 5w-40) has such a content

This is one reason why M1 0w-40 (and Delvac 1 5w-40) has been so successful and so durable. These blends give low temperature fluidity and high temeprature durability. Porsche Engineers are not silly and M1 0w-40 is the preferred lubricant for the TT Cayenne and has been from day one!

The fixation that some people have about one chemical component (ZnDDP of which there are over 30 variants) amazes me! There are many chemicals that make up a modern lubricant and the recently introduced batch (from 2004-5) are doing a measureably better job than ever before! It is important to avoid ILSAC GF-4 rated lubricants and to only use the correct viscosity if you chose NOT to use a Porsche Approved lubricant

Mineral lubricants should be avoided in all >MY84 engines - Porsche have avoided them too as a Factory fill since 1992!

WHB Porsche

Doug and Kevin - which would you recommend, then? Delvac 5w-40, M1 0w-40, M1 5w-40, M1 TDT 5w-40, V-twin 20w-50 or some other v-twin?

Doug Hillary

Hi Charlie,
it depends on whether you wish to use an Approved lubricant or not - the only Approved one you list is
M1 0w-40. This is a great product!

If the vehicle was mine I would use M1 TDT 5w-40 (which to all intents and purposes is Delvac 1 5w-40 which may have the "ESP" title now too). Delvac 1 5w-40 is not always easy to find as it is a Commercial lubricant - it is hard to find here in OZ too so I always purchase it in a 20ltr container

I am reluctant to ever move from an Approved lubricant's viscosity if using a non Approved product
The Approved viscosities are 0w-40 (30%), 5w-40 (70%) and M1 5w-50

If you intend to track the vehicle in long distance events I'm sure Kevin will chip in with his extensive experience and VTwin 20w-50 may be the option

WHB Porsche

To throw yet another wrench in the works - what about Motul? Basically - what should I use? Price no concern, but that Motul 300V looks like $25/qt!

Doug Hillary

Hi Charlie,
Motul do make an excellent range of lubricants - nothing "magic" but all of very good quality

The Porsche Approved and Listed Motul products are;

8100 X-cess 5w-40 (currency until October 23, 2008)
8100 X-clean 5w-40 (currency until January 16, 2009)

For racing, the V300 product has a great reputation but Castrol's 10w-60 is at least as good IMHO
Complex esters are part of their makeup too!

WHB Porsche

Thanks a lot Doug - I appreciate all of the advice.

Kevin

In the northern States we can get the Mobil 1 5w-50 out of Canada> Which is Porsche approved. Doug most likely list when the approval expires. For us in the the colder North 20w-50 VTwin might not be a option if you are driving your car in the winter.

Doug Hillary

Hi,
Kevin - As you say the M1 5w-50 is available ex Canada. The Approval on this lubricant expires on October 17, 2008.

This lubricant will most likely be revalidated without change as it is a World Wide product in Porsche terms. It has a quite similar additive package to M1 0w-40

I can never figure out why the USA does not have this version of M1, we have virtually all of them down here in OZ. ExxonMobil are not the World's best Marketers!!

Have a look at the link that WHB Porsche (post 61) and don't just look at the last three pages ,have a look at the lot , because you will see advice from people with in field Porsche experience like Charles Navarro and Steve Weiner as opposed to Doug , who may well have experience in the trucking world but no in the field experience(working on Porsche's for a living) with Porsche cars at all from the 1970's , 1980's , 1990's , and right up to now , not that there is anything wrong with that its just that we are not talking about water cooled large truck engines that rev no more than 1800 rpm and usually stay at their respective optimum torque area say 1600 rpm for hour's at a time , which is far different to a Porsche sports car .
Regards .BB.

Kevin just out of curiosity what are your thoughts about running 15-50w in our GT3's in the SoCal desert?
its the preferred oil for ALL kinds of desert racers in Sand Rails, Motocross bikes, Porsches and Racing lawnmowers. I would love your thoughts. I got chastised for suggesting it on the 996 GT3 board.
