how often to change oil in a 2005 clk320
What does your owners manual/maintenance schedule say? I'm sure your car uses synthetic motor oil. So every 10,000 miles
my '08 CLK : Oil change 1x a yr or 13K miles. '05 may not be different. But ck. manual. If you don't have a manual, ask the dealer or go online. Dealer probably will tell you to change every 3000 mi, like they used to, to make money.
