I abolutely agree. I have been using Mobil One since it was first available
commercially. My Vanagon has not seen any other oil after the first 10k
miles (she's now has 135K miles, orignal engine, orginal head - no leaks.)
I use synthetics on all my cars. Change oil every 10K-12K whenever I
remember or get around to it.. and change filters every 5K. Save the pain
and pollution of changing oil every 3K miles. Synthetics here in the SF bay
area cost about $4 per quart vs the $0.99 per quart for the regular stuff.
.. so you have decide if this difference in price is worth it. imho, it is..
definitely.
My understandings is that currently , all synethics are pretty much the same
for normal use. So unless you are putting it in a race car or a long haul
truck, it's a matter of brand loyaty which one you use. .. That is not true
with natural oil as the origin of the base oil determines the
characteristics. ie. Quaker and other that use paraffin crude from
Pennslyvania and the eastern oil fields has more wax then the mid-continent
fields which has better pour point .. (or is it the other way around!)
Also, it use to be that you are not suppose to use synethics until the
engine is broken in. This is because synthetics do not have the same seal
swelling properties as natural paraffin base oil which helps to set the seal
in for new engines. I don't know if that is still true.. one the safe side,
I would not use synethics in a new car until after 10K miles or so.

<clipped>Also I have heard that if you change just your filter every 6k
miles and just add the quart of oil that comes out with the filter, that you
can extend your oil
change durations from 6k miles to 10k miles or more (but I would ask your
mech
his opinion about this first) because the synthetic oil just doesn't break
down like normal oil. I have heard these great things about Mobil One. I
haven't researched any of the others so I have no idea if there is a quality
difference or not.
