I think this UOA looks pretty good. Blackstone is not worried about the oil viscosity.
To me the wear metals seem in line for a car that is driven hard.
I would say stick with the oil you are using...if you do try a heavier oil in the future I would definitely stay with a 5W oil. Oils with...
Yes...thank you! I'm planning on doing that in the next couple weeks.
Taking the car in for a rattle, loose door handle and the cam follower.
Do you think the higher Iron could be from the cam follower?
When I purchased this car the oil was about as black as I've ever seen oil. I know that is not a good indication of a oil's protective ability, but it was ugly looking oil to me and I couldn't wait to get it changed.
When I saw my first UOA come back and the iron was at 144 I was a bit...

Thank you everyone for your ideas and input.
I will do another follow up UOA on my next OCI later this summer. I'm running AMSoil 0w30 Signature Series (arguably the best oil AMSoil produces and IMO one of the best oils on the market).
I'm NOT going to add anything to the gas tank....ie...NO...

Seems odd. No Sn/Pb in the bearings, but shows in a UOA - no fuel treatments in any of the other OCIs?
Great question...this was the only OCI where I...
Awesome information guys. Thank you!!!
Do you have any thoughts about the tin. The tin jumped along with the lead.
Is there tin in the Lucas fuel treatment also?...or is the tin something I should be concerned about.
Thanks again!!!

Hey Guys,
My most recent oil change showed a higher amount of lead and tin vs my previous oil analysis. This OCI DID include some very tough towing...75 MPG into a 25 MPH wind for about 700 miles. The engine was working VERY hard during this tow. The truck was loaded down to near max payload...

I was looking at S5 and S6's over the weekend. How do you like the engine performance? ie would you buy another one? I see oil consumption is non-existent, which seems to be rare for this engine
Love the engine! I'm pretty active on the...
