Miricle oil additive?

[Ben Swann]

I agree, with Kneals experience with Castrol - 20W50 summer, 10W40 Winter
works consistantly well and change every 3K miles then no problems.

I'll throw in my experience factor on Synth as well.  I have tried many oils
and grades of them mostly in Audi I5's, but a lot of VW 4's and some GM eg.
older smallblock Chevy.

For the I5's in general, nothing I've used has kept lifters from ticking
better than Castrol Syntec 5W50.  I don't care about all the regurgitated
advertising hype that I keep hearing about Syntec not being "pure" Synth,
etc..  All oils need to have a source to form the molecules - either by
cracking non-synth stocks, or forming from smaller basic organic components.
int the end they get "synthesized" into something radically different than
what they started out as.

Now I have not tried some of the Royal Purple, Rotella Synth, etc. I keep
hearing about, as they are not generally available off the shelf around
here.  Probably very good stuff.   I have not found a Mobil Synth. that has
the visc. range of Syntec, but hear they have one out now.  I also know that
many of the newer engines like thinner oils with a lower Visc. so my
experience does not apply to them.

Anyway, I have been using Syntec for years with great results and have had
some things happen that are similar to the Syntec commercial where they
drain the oil and the engine keeps running.  When I use something different,
including Mobil. I with the widest range I could find, I don't get as good
of results - usually lifters ticking once the engine gets hot.  This is a
generality and some engines are lesss picky.

I forget a lot of the Organic chemistry, but know what has worked from
experience.  I believe Castrol has a good product regardless that its
competitor says it doesn't use the same manufacturing process they do -
hogwash!  What matters is the end result.

I really didn't want to get caught up in any oil war threads, but it bothers
me that I often see incorrect or misleading information get taken as the
final truth.  Just presenting a different view, as it seems some things
become "gospel" that shouldn't necessarily be.

PO indicated my 200q20v grew up on Castrol dino oils to the ripe old age of
140K by the time I acquired it.  I've kept up that practice for another 90k
miles so far.  I change oil/filter at "about" 4k.  I don't really see any
reason to pay for synthetics to be used in equipment designed before there
were synthetics.

I use dino Rotella in my diesel tractors.
