I just received my oil anaylsis and I noticed some unusual wear, I've been using amsoil 0w30 for 9000 miles now and I don't know if it could be the 0w thats causing the wear or something else, let me know what you think

You are supposed to use 5w30 so the oil you are using might be the cause.

So what does this indicate? Bearing?

I'm not convinced AMSOIL is the be-all and end-all of oils.

I run 0-30W

I concur. But the once a year oil change is obviously what makes it mighty attractive (among other things).

As for oil, in your area 0W30 is fine. I wouldn't concern myself to much about the numbers at this point. Your engine is young and still in it's break-in stage. Trending YOUR analysis is the important thing. Each engine is slightly different. I use Blackstone as well for my Jetta TDI I actually have sample to send in right now. Just keep sampling and watch the trend, I'm sure the chromium will start going down.

I say use what supposed to be in there.

On Mobil 1 site 0w30 race oil is not recommend for street use or daily driving

The correct spec is 5W30, but as stated 0W30 is acceptable. Here is Amsoils suggestion on oils for the 2007 MCSS: http://www.amsoil.com/mygarage/Produ...ONTE%20CARLO+C

Something of intrest. WARNING!!
http://www.vincihighperformance.com/...GE%20.HTML#CAM RETAINER PLATE WEAR!
We have noticed a considerable wear pattern on the front of the camshaft retainer plate, on the all of LSX series engines, including LS1, LS6, LQ4 etc trucks and on the new LS2 engines, as well. We believe this is due to improper oiling, between the plate and the timing gear. (see picture 1). This wear occurs with stock cams and after market cams as well, as it is a manufacturing defect not an aftermarket products defect. We have observed this wear on all of the LSX series engines with as little as 500 miles on them. VHP is bringing this information to our readers attention in hopes of preventing a serious engine failure. We have seen a material build up on magnetic oil pan drain plugs which, in some part, is due to the cam plate wear. We highly recommend using the Crane hex-adjust timing set on all cam installs, part number 144984-1. The bearing at the rear of the cam gear prevents most incidence of wear from re-occurring . (see picture 2). Here at VHP we have been notching the retainer plates for better oiling, to minimize this problem. (See picture 3). Upon tear down of test engines notching the plate and utilizing the Crane timing set has alleviated the problem Scroll way down.


I do strongly, recomend we change our oil filters every 3000 miles, due to it's small size.

thanks for the input, its also key to note that I've been using a 300lb force filter magnet on the oil filter, which means the presence of magnetic metals is much greater than this test shows
