Re: ??? for those that run your vehicles until death.
Had a '68 Mercedes 220D that I bought with 180K and sold with 315K. Changed dino oil at 3,000.<br /><br />New valve guides at around 250K.<br /><br />Bought my '98 ML320 new and traded it at 127,000. Used Mobil 1, changed it and the filter when the computer said it needed it, typically 10,000 to 15,000 miles. Didn't burn a drop when I traded it.<br /><br />The '99 ML430 now has about 84,000 on the same regimen as the ML320. Burns none.<br /><br />CAVEAT: The MLs computer monitors the oil condition (electrical conductivity) as well as keeping records of mileage, speed, oil temp, etc. Mercedes REQUIRES 100% synthetic and recommends Mobil 1.<br /><br />DO NOT take my experience as a recommendation, though Mobil will tell you that you can run 10-15,000 miles on a change and filter. There are too many variables to consider. My son's city driven, short trip ML asked for changes in as little as 5,000 miles.
