Re: Mobile 1 Extended Performance
Campbell, don't regret your post. This has stirred up opinions that
are great
to review and sometimes practical. Everyone has their reason(s) for
using a
motor oil of their choice, whither it be passed from father to son,
advertisements,
or just a personal study with recommendations from mechanics. I went
with
a self imposed study of motor oils and ended up using Valvoline Dura
Blend
(synthetic blend) 5w 30. Like you, I like the performance of my oil of
choice !
But, I do think the hard study goes to the oil filter. I've used
CarQuest (Wix)
filters and found they are very acceptable in an independent research
of oil filters.
O' yes, my oil and filter are changed every 3k miles. My TJ 4 banger
just might
run for ever, well until the Gladiatior hits the dealer's lot.

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!

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!
