Service Interval 4.6L BiTurbo
)a) Is the service interval (i.e. oil change) substantially different to last year's naturally aspirated engine.
b) Will be buying snow tires for the beast as I can't imagine driving the all season toboggans in the snow. Any recommendations on brands, pro or con.
TIA
Cold Canuck
b) I have Michelin X-Ice Xi2's on my Audi and my dad just ordered them for his '12 E550. Great tire
