I noticed Exon Mobil are hyping their new improved Mobil 1 engine lub. I
called Mobil and asked for a data sheet but was told they had none at
this time. He told me the new Mobil 1 was for extended warranty of
15,000 miles. He implyed it had better cleaning and wear control over
the older Mobil 1. I found it at Wal- Mart for $23.80 five Qt. jug the
old Mobil 1 was $19.95 five Qt.jug. I am just wondering how much better
the new Mobil 1 is?

I've said this before but it bears repeating. Even under the most extreme
conditions and circumstances you won't be running your engine anywhere near
the limits of what a decent synthetic oil can take, no matter what brand.
And even if you do, most likely your motor will die from the failure of some
part that is not lubricated by the oil first. In an overheat situation, you
will be getting signs and symptoms long before your synthetic motor oil
breaks down and causes the engine to seize up, and at that point I would
stop driving and be more concerned about what was causing the problem. As
for cold start-up, all synthetic oils have low temperature viscosity
stability and pour points far below the temperature that you would ever
consider driving your car. A good synthetic motor oil is helpful when a
problem arises, and good for preventing or reducing some issues but all of
the name brands provide vastly more protection that you will even need in an
automobile, no matter how hard you use it.

At a certain point even oil refiners have to "one-up" their competition to
maintain market share. Old or new, Mobil 1 will provide you with much more
service and protection than you will ever use or need.

My experience with the first Mobil 1 oil offered with my '74
Honda Civic was superb. I drove the car to the junkyard 12 years
later -- 12 years of tough service on San Francisco hills. During
the time that I owned it, the car never needed to have its engine
opened.

Having said that, I don't know anything about the "new" Mobil 1
oils. I'm a bit concerned that the older formulations may have
been cheapened to make the new version look better. I have this
concern about a certain brand of oil filters. In both cases, the
company has been acquired, which puts great financial pressure on
the outfit.

Two points:
- In doing some research about lubrication for a certain late 60s
record changer, for which an "adhesive oil" was specified, I was
told that synthetic oils have a tendency to leave a good film
coating on surfaces. The guy who said this is a refrigeration
mechanic and also a racing nut. I sought out his advice because
the adhesive oil is marketed in Europe by a firm that specializes
in refrigeration lube. The requirement in this record changer is
that the oil stay in place and not leak down by gravity into an
assembly that's got to stay free of lubricant.
- The flash point of the oil is much better (higher) with Mobil
1 -- thus, it's less likely to burn if it gets past the rings or
valve guide seals.
- I got exactly the efficiency improvement that was advertised:
8%
- I believe that the traditional Castrol formula is a far better
oil than most natural oils. I got a power improvement with it in
my Aerostar.
