Re: Mobile 1 Extended Performance
 

Nice post, Mike. About 12 years ago my depertment was responsible for
printing the owners literature and associated stuff for a high-end import
brand. To reduce cost of ownership and stay competitive with Lexus our
engineers ok'd 10k oil change / maintenance intervals, Our dealers when
berzerk due to potential loss of revenue. One of the engineeers met with the
dealer parts & service committe and gave a presentation on this topic that
was fascinating. He stated the combination of modern metallurgy,
computerized machine tools, modern lubricants and filter technology meant
that a contemporary engine could be run under normal conditions around 15k
between oil & filter changes without detrimental effect. Well, the dealers
went nuts anyway so we rolled the interval back to 7,500. Both BMW &
Mercedes use a computerized maintenance reminder system. Using synthetic oil
the Benz system will recommend a change interval between 10k - 20k miles. I
noted with the MB I leased between 2000 and 2004 that the system tended to
average about 14k. Since they were paying for maintenencce and I had no
plans to keep the thing, I followed their recommendation and never had a
problem The thing never used a drop of oil, either. Me, Hell, I'm old
fashined and change the oil & filter on my Jeeps at 3k!
