Just got this back from Blackstone for my brand new old Jag. I bought it assuming it had a blown head gasket/leaky cylinder liner. From what they show here that appears not to be the case (or the leak is still really small). I'm surprised this came back as well as it did - until about 50 miles before this sample was taken the thermostats were stuck open and the PCV disconnected. Little fuel and no antifreeze set me at ease, though flash was flagged (not surprised). Refilled with Rotella T 15W-40 and I'll sample again in 3-5k just to be absolutely sure.

Nice report for an older car... You should run AMSOIL 10w-50 motorcycle oil in your bike... best 2 wheel oil there is. period.

Nice XJS V12 report. I did an OCI with Mobil 1 0W40 a few months ago on my 90 XJS V12 and the Jag is extremely smooth with it... I was actually really surprised on how well the car ran after the change. I have been using Mobil 1 HM 10W40 prior to this last OCI...
