My first UOA. UOA was performed by Wearcheck on my factory fill.
Driving habits are mostly 160km highways on weekends, and 40km on traffic jammed rural highways during weekdays. This was the very first oil change for car, sample was taken by technicians at dealership. Normally I change my own oil but I was getting some other work done at the same time so I asked them to take it.
Not sure HOW they're detecting diesel in there!! Filled with Petro Canada 94 octane (10% ethanol) for first couple fills, then switched to Shell 91 (0 ethanol) for all subsequent fills.

Recommendations:
We advise that you check the fuel injection system and ensure that you are using the correct fuel type. We advise that you check the air filter, air induction system, and any areas where dirt may enter the component. Oil and filter change at the time of sampling has been noted. We recommend an early resample to monitor this condition.
Code:
Time on Unit 60days
Time on Oil 60days
Time on Filter 60days
Mileage: 4950km
Contamination:
There is a high amount of fuel present in the oil. Gas Chromatography testing indicates that the fuel dilution is diesel fuel. There is a moderate concentration of dirt present in the oil. Tests confirm the presence of fuel in the oil.
