    UOA question

    Hey, thanks. New fill is vanilla Mobil 1 5w30. Next fill will likely be Harvest King full synthetic. This fill saw a very high percentage of highway miles, probably 70-80% of the total. I subscribe to the 'drive it normally without being stupid' theory of engine break-in, and the CX-5 was no...

    Winter tires for BMW X5
