Hello, I am new memeber and i wanted to know what miles would be appropriate for ml320 get a tune up and get all the spark plugs changed. It has exactly 88000 miles and i think its never been changed. Also when i turn left the car makes a slightly strechy noise on the front, . Please do let me knoww....thank you

 

According to service schedule at 100,000 but I would check at least one to see if they are OEM and how they looks like, they may not be the original any more. If they are original or new aftermarket, I would suggest replacement. For the front suspention, I would regrease all ball joints with fine grease gun needle through their protective rubber booths and noise should stop after couple days of normal usage.

 

hello,
Thank you so much for the advice ..and i was also wondering would mobil 1 high mileage oil be good for the ml ?

 

No. Use Mobil1 0W40 Full Synthetic European Formula Oil (Walmart or local Auto Zone). Need 8 quarts plus one OEM filter # A 000 180 26 09 (MB dealer or internet).
I would not recommend using regular oil in your ML, if you would change it every 3,000 miles, you will have to do it 3 times instead of one synthetic and it would cost you more.
