Here is the experience on one who has owned many older used-cars (probably
more than 2-dozen): No doubt ALL oils have improved greatly over the last 2
or 3 decades, but who has an extra life-time to check out all advice & 
advertising claims?  I presently own 3 high-mileage old cars...all of them 
were using a fair amount of oil at 60,000 80,000, & 110,000 respectively,
i.e. something like 1 qt/500mi. All were full-size v-8's. (I had been using
Mobil 10W-40 which appeared to be quite satisfactory insofar as no sludge
build-up).
   Then without doing mechanical work on any of the cars, I simply changed
over to MOBIL-1 (SYNTHETIC OIL). Surprisingly, in all three cases they be-
gan to gradually use less & less oil...not to mention running very well 
and an obvious improvement in spinning over while cranking in sub-zero
weather. It probably is more stable at high temperatures also because one
of the cars is a 74 Olds-98 which I use only for pulling a 21-ft travel-
trailer in hot summer-time.(has had Mobil-1 for the last 20,000 mi).  A 73 Dodge went from 1qt/500 to 1qt/1200mi.
  I hear some talk of seals beginning to leak, but I've had Mobil-1 in
these cars for at least 3 years and non of them developed any oil leaks.
 (The 70 Ford Stat. Wgn now has 123,000 on it and has never had any sig-
nificant mechanical work....still purrs like a kitten)
   One must use his own judgment if he thinks there is risk in putting
different oil in a dirty engine....I always do the "flush" routine before
changing....I have switched over in 6 cars and had no problem.
