This sample was taken at 65,003 miles with a 4113 mile OCI. It was analyzed concurrently with Dyson Analysis Premium Service and Blackstone Labs. Prior to this sample, PP 5W30 (New formula)was run for about 1000 miles. I only ran it for a short time because the dealership had put a can of BG 44K in the fuel tank during the 60K mile servicing. I wanted to eliminate fuel additives as a source of high lead wear and also wanted to try GC Gold in this vehicle.
Previous UOA's were done by B/S at 59,900 miles (5K OCI) with PP 5W30 (EOP formula), and at 37,250 miles (2.8K OCI) with ML syn 5W30 SL.
There was no make-up oil.
The OEM air filter and air box were filthy (this was supposed to be taken care of on the 60K service, but wasn't).
The oil filter was Pure One.
Chevron Supreme gas used mostly.
There were no fuel or engine additives during this recent OCI. Techron fuel system concentrate had been used in the past.
My wife drives mostly 4-5 mile trips to town in this vehicle. It doesn't see much steady highway/freeway driving.

I know I have issues with this vehicle. I'm glad I used Terry's service this time to get a game plan to correct some of these trends. I wish I had tried him earlier while the car was under Infinity warranty. Since this UOA, I have replaced the air filter and cleaned the air box, replaced the spark plugs (and valve cover due to a leaking O-ring seal), changed the PCV valve, and use Shell V-Power gas. I'm still using GC Gold and Pure One oil filter. I will consider RLI 10W30 HD BioSyn if the next UOA doesn't show any improvement in the fuel dilution problem.
