Quick question, guys.
I now have just a bit over 75,000 miles on my '05 C55. Change oil every 5,000miles. Yesterday got message to add qt of oil at the next gas station. Just before my last oil change I had the same message right before I had to go change the oil.

Question: Should I be concerned? If in driving 65,000 miles I only had to add oil once and now I had to do it by the end of my 5,000 interval between oil changes - is this normal? I doubt we have such a high milage C55 on the forum but any input would be appretiated.

P.S. my tech says it's normal but I just can't see why would car wont need any extra oil for 65,000 miles and then start asking to add1 qt every 5,000.

Thanks guys!

1qt of oil over 5,000 is well within normal limits.

Has anything changed with your last oil changes??? New garage? suck vs. drain?

What I'm getting at is - are you sure that the last two oil changes are the same as the previous to those, and that the engine is being filled correctly. If you're starting out 1/2 qt. down, for example, you're reaching the 'add 1qt' sooner.

Thanks for reply, my car gets serviced at the same place by the same guy. I wonder if he did something different past two times or is it something internal?
I'm taking my car for the next oil change on monday and we'll see how it goes.

Thanks again for the reply. Btw, where in Chicago are you?
