My dad has a 1999 C280, cool car, lot's of pep.

After driving his 1977 300D, before he sold it to me, he is used to every 3000 miles oil changes.

He checked the driver's manual for the oil change interval, and it pointed him to the "check it out button" on the instrument panel that gives the "miles til.....oil change" on the instrument display. To his suprise, it was suggesting approximately a every 12,000 mile oil change interval. He checked with his dealer and they said that was right.

What's up with that!!!!!!!!, and can anyone confirm the oil and other fluid change intervals for a 1999 C280
