Ehh, I still think those oil change intervals are more conservative than they need to be.
I've been sending samples to Blackstone Labs since I bought my Nissan Altima new back in Dec '06. I sent the first sample when the engine only had 733 miles on it in order to find out if there were lots of break in materials in the oil (there wasn't), and then a sample with every oil change after that.
Since I've been using Kendall Semi-Synthetic oil in the car since the first oil change, I've been changing the oil somewhere between 7500 and 9000 miles. Each UOA came back with flying colors, and I'm anything but gentle with the car.
Right now I'm waiting for the results for my first UOA with the Porsche since I bought it back in Feb.
I'd rather know what's going on, rather than hoping everything is okay, or throwing money down the drain for "peace of mind".
BC.

Charles Navarro of LN Engineering told me yesterday that he also evaluates samples for $25 when you buy oil from him (which I did). I think about $40 separately. I'm going with Motul 300V and continuing to change annually at the 5-6k mileage.
He and Jake Raby are friends and are working together on M96 issues and proper oils for us. I'm using the LN eval from now on the help build their database.
If you have not been to his site and read his findings and recommendations you should.

10W40 every 3000 miles for me...not taking any chances after all I've read on the topic.
Now just pick your flavor; mine isn't M1.

Are you talking your Box at 3K changes? That would seem a bit overdone, assuming your drive the car a bit?

That's once a year for me, otherwise I change my other cars at 5k miles.
I did install the LN billet oil filter adapter and magnetic drain plug (wow, is that thing strong!). Next up is the 160 * t-stat sitting in the box near my desk...want to get to that in the next week or two.
I'll see Charles Navarro up at Road America this weekend for Chicago PCA DE...time to get the '73 911 on the track!

Just got off the phone with Charles.. he needs a coil pack. He fried on sitting in traffic on the way to Road America.. can anyone help?
FYI: Our Grand Am team was sponsored by Motul. I HIGHLY recommend it over everything else on the market right now. We dyno'd and dyno'd..
