Let's talk Oil Addiditives!
Seems like some folk are keen on that Chevy assy lube.. what's so great about using that stuff in the 911 motor? what are it's properties that make it worth adding? Are you adding it to M1 as well? And how many bottles per oil change?
Anyone have any experience with Swepco 502 or opinions of same?

We have been using Joe Gibbs Driven 'Break-In' Oil for a while now as this still has high levels of ZDDP and has been specifically designed for bedding in rings etc.
Maybe worth a look goolgle for joegibbsracingoil

The GM Cam and Lifter lube is P/N 12345501. My local Chevy dealer has it in stock.
Their other product is GM E.O.S. Assembly Lubricant Part #1052367. The number is different in the USA. I think the formulation is the same, just the size of the package is different, 500ml for Canada, 1 pint for the only country in the world not yet metric.

Don't use the Joe Gibbs oil. It is forumulated for racing - i.e. it doesn't have many of the corrosion inhibitors, detergents, etc. in regular oil. This has been hashed around in every forum on every board.
In an 911, EOS will not significantly raise the zinc levels. You are best off using oils that are not Energy Star certified and that don't meet the latest SFI spec. I would suggest Rotella or another diesel oil.

Matt: you wrote, "In a 911 EOS will not significantly raise zinc levels".. why would it not? Is Mobil 1 syn. Energy Star certified and does it meet the latest SFI specs?

It won't raise the levels enough becuase their simply is not enough zinc in it to counteract the 12+ courts of oil in your car.
Mobil 1 is API SM (sorry meant that before) meaning that it passes the latest requirement and has low zinc levels (for cars with cats). In turn, it's not as good for our old Porsches.

So you are saying you believe Shell Rotella in I am guess an 15w-40 would be good? Based on the article I read it has the high levels of zing and phosp. and would not require the EOS additive..?

Correct. What I've seen and what I've got from the oil companies, Rotella (or other diesel oils of your liking) is the best choice right now for a street car. You don' t need the EOS with diesel oils.

Shell has recently changed their formulation of Rotella to correspond to the requirements of fleets running the new diesel fuel and cats. I queried them on this & they told me that they added a pack that maintained the utility of Rotella for older, hi perf, hi rev, non-cat gas engines. That sounded great, but I'll withold judgement until someone like LN Eng (Charles Navarro) confirms that the "new" Rotella is fine w/o having to add any additives.

Nothing against Charles, but he's not an oil expert. When you call Shell, you're talking with people that have direct contact with the R&D guys and can tell you way more than any of us. If you really press, you can probably talk with the actual oil engineers at Shell.
I got my info from the Head of R&D at Shell when he spoke at PRI. There was also the Head Chemist (Phd in Chemistry) who also spoke.
The difference between the new diesel requirements and the API SM are very different. The Rotella is the best bet, but do as you want. It's not my motor...
