My oil change on my '05 X5 4.8is is nowhere near a $100. A 8qts of mobil1 = $38.99 Costco + Mahle filter kit autohaus 7.95 for a whopping $47. (Disclaimer:I bought four cases on sale last year at Costco I bought 2 cases and my wife bought two cases plus the $9 rebates/case. I regularly utilized the free shipping on orders over $50 at Autohaus.
