I was unable to determine which Castrol the dealership put in for the my first oil change. I guess that UOA will remain a mystery as to exactly which oil it was.

Here's one I just received on my most recent oc. Oil was AMSOIL 5w30 Full Synth Euro Blend. Changed at just under 4000 miles as it was burning some. I drained about 3.5-4L. I remembered to have the sample vial right next to me when I removed the plug. Sampled it correctly this time....

I also did the TBN per Gpshumway's request.

They mention that some of the higher metals could have been due to racing or spirited driving. While I do drive "spiritedly" on occasion, this car is not raced. I mentioned in my other post that I forgot to have the vial with me when I took out the drain plug so I had to take my sample from the drain pan.

Replaced with AMSOIL 5w40 Euro Full Synth Full SAPS. I'm planning on changing this at 5k, and will do another TBN.
