Crush ring and Castrol

[mikefocke]

who set up the deal to give Mobile all the promotion (in exchange for what?).

How are we sure this co-marketing deal is for the benefit of customers or not just another deal that provides kickbacks?

If it was just in a TSB where their recommendations were, I'd be more inclined to believe it was engineers speaking.

Let me suggest that Porsche probably gets all their oil and certainly gets the benefit of Mobile advertising the Porsche exclusive-use. Every time Mobile says the word "Porsche" in an oil commercial, Porsche marketing benefits.

And those who analyze the internals of Boxster engines that have failed or are beginning to fail seem to agree on one thing...that the oil recommendations that Porsche has made and continues to make for the M96 engines are not the right way to protect the engine based on their analysis of hundreds of engines and the contents of their oil over several years.

And many say not to use Mobile 1 and recommend a thicker base viscosity.

Can JFP be right in thinking that the Porsche engineers choice is suspect too?

My next change won't be 0W40 and won't be Mobile 1.

There are hundreds of Porsche approved oils. No need to use Mobil 1. I use Red Line 5W40 (not Porsche approved) in the Bosxter.

I do plan to try Mobil 1's 5W50 in a new car I am getting soon, since I will try to drive it a little during the winter.

When Red Line actually obtains ACEA A3, B3, and B4 ratings (they currently do not have any ACEA ratings), they might be worth looking at, but not until they have ACEA...............

"you know more than the Porsche engineers! That's awesome!!"

Unfortunately, the Porsche engineers had to work with what the accountants and marketing dept gave them...which is why we have d-chunk engines, weak IMS bearings, weak cam tensioners, broken cheap plastic pieces and on and on and on.

I don't question folks like JFP, Jake and Charles because they represent "real world" not factory hype. Porsche wouldn't even admit the problems with the M96 engine design; do you think they care about the oil they recommend other than who's paying them the big marketing dollars? I remember when all my Porsches came with Shell stickers as factory fill.

I use Castol Syntec 10W40 and recently paid $4.99 qt at AutoZone...I wouldn't put Mobil 1 0W40 in my lawn tractor.

So let's agree on one thing - the oil discussion is like discussing religion, everyone has a different opinion...

I got what I needed out of this thread - go to Walmart for Castrol, which is my choice. But still not sure if anyone answered the size of the crush ring, i.e., is it 17MM, 20MM, etc.

IMO, I agree with the previous point that the Porsche engineers are told what to work with (M1) and in my occupation, upper Mgt. gives us the project end dates from hell and tells us to get it done knowing it's unrealistic! LOL, all the same crap...

Thanks a ton,

Crush washers are not universal, either in ID or thickness. That said, there are many applications using the same size washers. My suggestion is to take your drain plug to the store while the oil is draining and match it up.

I just went to the local dealership. Gave them my year and model and since they were so cheap (45 cents) I bought a couple. Plus, this had the side benefit of me being able to google at all the shiny new cars.
