Thanks for informative post. I know it's an oil form, but must
say I bought an 09 Merc Milan 4cy auto/air/sunroof/Microsoft
sync in Jan for the unbelieveable price of $16,300. My wife
drives it on short city trips to see her patients everyday.
Use nothing but MC semi-syn and change it every 4 months or
5K. It has not used a drop of oil, consistently gets 24 to
26MPG in town (depends on temperature and AC use) and here's
"the kicker" for me.....MY MILAN IS THE ONLY NEW CAR OF 22 THAT I
HAVE BOUGHT THAT HAS NOT HAD EVEN ONE WARRANTY ISSUE OR NEEDED
TO HAVE DEFECTS FIXED IN THE FIRST 9 MONTHS...and that list includes
a Honda, a Acura, a Mercedes, a Jeep, a Hyundai, and two
Infiniti's in the last 5 years which all had multiple defects
and trips back to the dealers!
