Default USED OIL ANALYSIS: 1st time w/ GC 0w30

This is my first UOA using GC. I switched to GC after doing 2 cleaning/rinse cycles of Auto RX. I also added, I believe, 8 oz of LC with the initial fill and about 1.5 ounces per 1,000 miles. It's also the older M02 batch of GC which, IIRC, was shown to have more iron in a VOA. I also added about 1.5oz of lube control a couple hundred miles before I changed it (maybe why it looks like it thinned out a bit?) . I originally planned on keeping it in awhile longer but the oil was in their for 1.5 years and I started feeling guilty, so I changed it.

I was running a Baldwin filter for the majority of this cycle and am now running as Wix (which has more pleats than the Baldwin I took out). I also always put a thin film of silicon grease on the rubber sealing surface of the filter to help with sealing. I don't know if this could be causing my silicon to be a bit elevated or not.

comments?? Patman?

Silicone is not Silicon. Unless your putting dirt grease on your seal, they aren't the same element. Looks like its doing good though right...

True but there is plenty of silicon(Si) in silicone products. Most of it being in a molecule called dimethylsiloxane (AKA Dimethicone).

I jsut sent my GC sample to Terry, 2K miles after a head/lifter change. Nice to see someone else using his services.

Very nice.

But the more important question...are you happy with how your car is running? I too have used Auto-Rx, and now use LC-20 along with my Euro Amsoil. It isn't eating oil for the first time in its life.

yeah, it's running great. It used to use maybe 1/4 qt per 4,000 miles and now I really doesn't use any. I also have a AMW catch can......
