Everything old is new again. ARCO used to sell ARCO Graphite motor oil,
which was motor oil with fine graphite particles mixed in. I wonder if Krex
is being run by ex-Arco sale types .

ARCO stopped making Graphite Motor Oil because it polluted the
environment. I used to put ARCO graphite in my engine. It worked
great.

I used to design face seal. Carbon graphite is used exclusively in
this application where lubrication is marginal.

Make sure the graphite could pass though the filter. Other than that,
it does not hurt.

If your engine is designed properly, all the mating surface should be
oil lubricated and the hydrodynamic film is present. However, it is
not always the case especially during start up or hot. In some areas
such as valve seal, the oil film is not always guaranteed.

Did KREX guaranteed the the KREX graphite will not clog the filter? If
it does, then it may do more harm than good.

How do you know? Did you strip the engine down to see?
Did you tear down an identical engine that had not had
graphite in it at the same milage and compare?

Krex Graphite is a non chemical lubricant used excusively by new car
dealers. The graphite is less than 1 micron in size and only 6 oz are
added to your oil change. The dealer adds this to your oil change to give
you Roadside Assistance and Road Hazard Tire Protection for 120 days from
the date of the oil change. The product is nothing more than 10 weight oil
with a little bit of graphite added. It was delveloped at Packard Motor
Car back in the 40's.

Mechanics have a name for additives of that sort.
They call it "Mouse Milk".

Stay for away from these kind of dealer profit producing additives.

Honda says not to use them ... but dealers go ahead and do it because it
makes the service area more profits.

Just say no.
