the car comes with 0w-40 Mobil 1 oil, which is a european blend. The oil filter is used on mitsubishi motors and there are a number of different brands available that will fit.
I have had no problems with using Mobil 1 in all my vehicles for years now. It is a bit more exspensive but to me, it is worth the added cost.
The front and rear tires are different sizes and widths. If you are seing uneven wear, then something is out of adjustment.
