RE: Mobil 1 for how long??

[Anand Dhanda <dhandas@cwixmail.com>]

well whatever Audi uses (Mobil 1???) for their oil changes at the dealer is
what I use and try to keep the oil changes at 7500mi but have stretched it
to over 9200mi once because the dealer didn't have time for it... but after
about 6500mi it doesn't feel as strong as it does when the oil is fresh, and
at 9000mi it felt kinda weak (30v A4).

Subject: Mobil 1 for how long??


I just got off the phone with Mobil 1 tech assistance (800-askmobil).  I
was inquiring about ol change intervals, in addition to other things.
The guy I talked to said to get the full benifit, I should go all the
way to the manufactor's recomendation (7500mi., '91 200q).  He said that
origionally, Mobil recomended 25000 miles, but revised that so as not to
conflict with the manufacturers.

The tech claimed viscosity breakdown, even in a turbo engine would be
insignificant at 7500, and as long as the engine is in good condition
without significant blow by, and a high quality filter was used (of
course he suggests a Mobil 1 filter), the oil can easily .  suspend
contaminates for that interval.

I've always used the 3000 mile interval, and going out that long scares
me.
Any btdt, thoughts?

Thanks,
