[Shotimes] AMSOIL By-pass filter

[Donald Mallinson]

It is easy to find an example of anything, to prove any 
theory.  One or two or a few motors that have bearings go 
before 200,000 miles does NOT prove ANYTHING about the oil 
used.  Not enough samples.  If you want to go that route, 
then how many non-synthetic motors have had bearings go bad 
BEFORE 150,000 miles?   Oh, lets say ..... A BUNCH!   Come 
on Ron, a few motors does not prove anything.  I like Doug 
Lewis but a few bad cams does not make a jury trial case 
against synthetic.  Not when virtually every other top 
mechanic can't find anything wrong with using it, and in 
fact most recommen it.

In the history of the SHO, how many cams have gone bad in 
non-synthetic cars??? enough to totally condemn conventional 
oil by your own example, but I don't draw that conclusion, 
because in the history of the automobile, cams have been 
going bad (flat lobes, bad lifters, and in our cases bad 
shims) since the first car was made.  Some cams just have 
bad metal or heat treatment.  Something goes wrong, and it 
isn't the problem with the oil or the maintenance.  It just 
happens.

As has been said before, YES, if you change a good 
conventional oil every 3000 miles with filter you are 
treating your engine well.  Same thing with synthetic.

If you extend oil changes with a synthetic designed for it 
(like Amsoil) with oil analysis, then you are also treating 
your motor just fine, plus you get the increased temp 
capability.

In 0 degree weather I can hear the oil filter bypass open 
upon cold start with regular oil, even 5 viscosity.  I have 
also had oil seep past the oil filter seal there was so much 
pressure.  Do you think you are treating your bearings well 
in this case?

Hell NO!  With synthetic this doesn't happen.  Case won in 
my mind, I prefer oil to flow when cold, I Prefer it to not 
break down on lap 4 of 8 on the track in heat.  Synthetic 
performs better in both extremes, and provides better 
protection at every other temp.

Is it worth it to you?  NO. We all understand that.  Is it 
worth it to me?  Hell yes, and I don't appreciate having my 
intellegence questioned just because I choose to use 
synthetics.  I don't call you names because you choose to 
use oils or radar detectors I don't or won't.  Each to his 
own.  But ratchet back the venom just a bit please. It 
doesn't play well among most groups.
