At about 8:30PM on July 2, 2010, I Pulled off my 2005 ML350 out of the Garage where it had been kept for over 7(seven) days, to the driveway. As I was driving off to visit a friend, I had difficulty steering the wheel plus a short-lived squicky noise.

when I came back to the house, I stopped at the driveway and walked back to the garage only to find nearly a quart of steering fluid on the garage floor. Later that evening, I brought the car back into the garage and mistakenly when i open the hood, I picked up an almost a quart of steering fluid and poure it into the engine oil and later realized it was not the steering box cap that I had opened. Now the question is, should I ignore the mixture till my next oil change or go for oil change immediately ? I changed the oil and filter about 3 months ago with synthetic oil and had driven the car for only about 1,000 miles before this incident.

    Better safe than sorry do oil change w/filter with non-synthetic (cheaper) then in 500 miles or do another oil change w/filter returning back to the synthetic if that is your preference. I know it seem a bit much or like over-kill, but I know how expensive Mercedes-Benz repairs can be, especially if something major were to go wrong.
