Porsche Approved Oil List

I was wondering what you would put in a 60k mile 2001 boxster "s"?
I will use mobile 1 but I don't know what the "## W ##" means. what does the # in the equation stand for?

The"W" stands for "winter" or cold weather viscosity/weight; a "0W-40" oil has "0" in the cold.

I would not use any oil with a "0W" rating, regardless of maker. We only use a 10W-40 full synthetic with ACEA A3, B3, B4 ratings in all our customer's cars, and it gets really cold here....................

Cool, thanks, hey what does the 40 stand for?

The viscosity/weight when hot............

0w-40 M1 is fine for our cars. M1 has put different additives in the oil to replace the ZDDP. (from a tech session at the Porsche Parade in Keystone last week.)

Please look at your warranty book and show me where it requires us to change the oil to maintain the factory warranty.

I missed that tech session because I was working elsewhere, but I did put the same question to the guy manning the Mobil 1 trailer, and he said that the M1 that we use will not break down between 15K intervals. I was concerned about annual oil changes with low annual miles, and he said that as long as our cars were fuel injected, M1 sitting for long periods of no use is no problemo.
It is the carburated cars that sit around, bounce around on trailers, etc, that causes the carb floats to stick or bypass, thereby dumping gas into the oil and contaminating it. But for us late model Porsche folks, especially Boxsters and later 911's it is the 40W (weight and viscosity) that is important in the M1 "european formula" (Porsches, Mercedes and BMW). The guy was a storehouse of knowledge about Mobil1 products for all cars and all the way up to his own Diesel tractor/trailer.
I can't tell for sure, but are these the same mugs used at the Beerfest?

You might not be so quick to state that if you looked at UOA data collected over a couple of years.................I’ll reiterate what I said earlier: “I would not use any oil with a "0W" rating, regardless of maker.” Period.

I've used it for more than 100,000 miles with no issues, no oil usage, and perfect oil tests by Blackstone. No emotion or religion, just the facts. Also my lifters do not clatter at start up.

Yes, probably given by a sales person from Mobil. One of the Parade organizers asked me after the 356 Lit Meet earlier this year to do an oil talk like I've given to many clubs and at national events (I was on vacation, so I couldn't), but I wouldn't have since if I didn't have anything nice to say, so I was better off not saying anything at all. :-) Mobil was a sponsor for the Parade and it was implied that I had to play nice, and everyone knows what I think of the new Mobil 1 formulations.

Like I tell many I speak to, if you insist on running a Mobil 1 product, there's always the M1 10w40 4T Racing motorcycle formulation, that is closest in spec to what would have been used back in the late 90s when these engines were new (in respect to Zn and P). You could even run a 50/50 blend with the m1 0w40 and motorcycle oil if you wanted, that's what's in our Boxster now. Can't wait to see the used oil results.

Charles I have attended one of your seminars and I have sent you one of my UOAs (at your request) that clearly showed that 11,000 miles and 17 months of use of M1 0w-40 was fine.
