In a climate like FL, why not use 15-50 or 20-50? A lot of people believe you want the zinc/ZDDP over 1000 for these (and other) engines.
I am going to disagree w/ the value of this oil testing on a 944. Having worked w/ oil analysis programs in the past (US Army AOAP and Caterpillar), this testing is designed for large scale fleet vehicles and requires metallurgy information from the engine manufacturer and significant historical/trending data to be useful. For example, Caterpillar test runs 100's of engines on dynos for hundreds of thousands of miles, generating oil samples for this this type of data use. Then data from thousands of engines in the field are continuously monitored over their lifetime. There just isn't that kind of compiled data for 944 engines. And oil analysis is performed primarily as a cost saving and green measure, to reduce the number of annual oil changes performed on fleet trucks or equipment (FedEx, UPS, etc). On your personal car, for the cost of an oil analysis, why not just change the oil?

In my opinion, I am skeptical that Blackstone would have enough information to tell you the condition of your bearings, piston rings, cylinder walls, etc. of a 944 engine.

Thanks for posting that, Grant. Supports one of the messages I've been preaching for a while: If you're going to use Mobil 1, the *only* product you should be using in a 944/951 is 15W-50.
ZDDP gets used up as the oil wears, so it's nice to see that your levels are still >1000 at the oil change.
The guy from ~6 years ago should not have been using 10W30. Wrong formulation, wrong viscosity... just plain wrong.

What's the price for single analysis?

+1, I use oil analysis to determine health of my 944 race car engine, I have spare engine to build but the oil analysis is used to determine when to pull and replace engine if rod bearings are starting to fail
