This is a Napa oil sample result, I copied the data so you don't have to download a file. No makeup oil added. Had 1 long 1500 mile road trip. The rest mostly 10-20 mile drives with little traffic. Lots of wide-open throttle. Engine seems to run very strong and on the road trip returned a best full tank of 33mpg. Usually, I get about 22 though. The oil had a strong fuel odor but TBN and viscosity look ok. Does anyone see anything concerning? I ran the sample because the car has a short ram intake on it with a cone filter and I was curious if it was capturing dirt well enough. This car has been running Mobil 1 since it came off a lease in 2009. I refilled with M1 0w30 AFE and a bottle of Lubegard Biotech.

Silicon level (dirt/sealant material) satisfactory. Water content acceptable. Viscosity within specified operating range. Action: As oil and filter(s) already changed, resample at next recommended interval to monitor and establish wear trend.
