Universal Oil Analysis

Instead of pontificating about how good/bad/horrific any one product is, you pay $25 to have a lab actually run some chemical analysis on the used oil to then provide a modicum of empirical evidence which may fuel subsequent juvenile arguments about what product is best

Its a good thing to do for *yourself* if you are concerned about a problem with the engine, or you want to run extended oil change intervals (OCI): this way you can see how your engine works with a product. Products break down over time (additives, viscosity modifiers, etc...).

In general for the street, most good synthetics can be run for 6-7500 miles for example, but its nice to see a report after 7500 miles that the oil is still performing within spec. I have done it for previous vehicles when running up 7-10K OCI's on commuter cars, and when I suspected issues. Blackstone is a good lab, the one I used personally as well.

I have no plans to do it on the Z: OCI for this car is ridiculously low from Nissan so while in warranty, I'll follow their schedule which for my driving, means every 6 months.
