07 Suzuki Grand Vitari

Hello,

I had an unusual experience this day.

I have setup a new dealer - up the street.
This morning he changed the engine oil in an
2007 Suzuki Grand Vitari 2.7 L Gas engine.

The vehicle did not drive 30 miles and
the owner was back in to Paul's shop ...

With Paul being a bit more than concerned.
*******************************************.

Certainly - he was unsure of what was going
on ... as everyone in the shop there was
listening to a set of sounds coming out of
the engine. ... all saying ... they were not
there "before we put your AMSOIL in ... "
********************************************.

Rather than leave Paul hanging -
at the mercy of what other people would say.

I go to my tool box and pull out a
NAPA 3289 Oil Pressure kit.

This kit allows the user to remove the engine
oil filter and directly - replace it with
a fitting and bell assembly - that empowers
the user to attach an oil pressure gauge.

The test results were that the pressure
fluxuated back and forth between 18 and 20#s
pressure - hot.
*******************.
Listening to the engine - we heard a sound that
only existed at idle.

That went away - with engine rpm
and increased pressure.
************************.
And yes, we did drain the engine oil pan
and the engine oil filter.

Yes, We did catch the oil in a clean pan
and searched for debris.
*****************************.

And what was found was some type
of material that resembled a filling
that one may have come out of a tooth ...
especially if a crown point may break off ...
in a molar.

There was NO bearing material or any other
kind of debris that resembled anything
related to lubrication failure to the
crankshaft or bearings.
*************************.

The one single point I am making here
for you is this.

Our Amsoil - does not cause problems.
It is a problem solving lubricant.
*************************************.

Initially - there was no sounds to be heard.
As the engine ran - a sound developed.

With the debris that was washed out into
the catch pan - there is simply just one
or two points where such a material could
originate -

1: a piston skirt/wrist pin area
or
2: an oil pump that had a piece of
it's housing damaged - in some other
incident ...

Now with the owner - having the engine oil
changed for the first time - since her
dad helped her buy the vehicle some 2,000 miles ago.
********************.

So,
As to my understanding of where the noise or
sounds were coming from ...
While engines can and do run with minimal oil
pressure - They require that the oil pressure
needed to keep the oil pressure switch off -
be maintained.

(There was never any problem with the light coming on.)

and that the hydraulic pressure -
Yes, the engine oil pressure is - when
applied to hydraulic lifters - then a hydraulic
oil/fluid that is used to pump up and hold solid
the lifter as the motion point for the pushrod
or rocker arm - to open the engine valves.

The required pressure is required ...
Or there is what is referred to as vavle lifter ticking.
***********************************

At idle - there was NO valve lifter ticking.
At idle - there was 18-20 #s pressure at the oil
filter base fitting.
At idle - there was a sound that existed.
And then went away - with increased RPM.
*****************************************.

And it was the same - with the Pennzoil 10w30
that was installed just after that effort of
removing the Amsoil installed.
*********************************.

So,
The real set of questions that we have for
the previous owners - are:

1: What did your service shop - dealer
do for your vehicle - while it was serviced
since it was new?

2: Was your vehicle ever wrecked at some time
in the past - that could have created a crack
or stress point in the oil pump - you know -
Was the oil pan replaced ? and the oil pump not?

3: The Thrust washers on the crankshaft journals
or bearings could have become tagged ... and allow
the crank to walk - in it's bore ... causing a set
of sounds.

4: As the engine oil was that that came from
a new/used car dealer - could the engine oil that
they had installed - had some motor honey or something
like it installed to cover up such a noise that existed
when it was in their service dept - hoping not to have
to install a replacement engine - themselves ... but to
wait - until a new owner had an oil change and then
brought it back for repair or replacement under warranty ?
**************.

What I am finishing this post about is simply this.

Amsoil synthetic lubricants - can not -
They are incapable of not providing excellant lubricating
qualities - under all conditions - cold and hot.

The synthetic lubricant that was installed - had nothing
to do with the engine's low oil pressure of 18#s.
The viscous weight of the oil was right.
And

Because each and every bottle of Amsoil has it's contents
tested - by spectra-analysis - before it is shipped -
IT is physically impossible for this bottle of Amsoil 5.30
to even be considered to be suspect in this noisy engine.

None the less,
I - myself caught the 30 mile driven engine lubricant.
I used a paint strainer and funnel and filled back
up the gallon bottle that the lubricant had been shipped
sold and delivered to the shop.

And if anything really comes out of it all.
*********************************************.
I have the bar code off of the bottle that is directly tied
into a computer data base where the spectra-analysis report
of the oil was done - (prior to it being sold) can be located
and
compared to the now present condition of this lubricant.
************.
**************.

Myself -
I have No problem installing it in the next gas engine
that comes to my door - for Amsoil Synthetic Lubricant
Oil change.

New filter for the engine.
The same oil.
And keep on going a full year - 12 months or 25,000 miles
on both engine lubricant/oil and filter.

all must be in known sound condition -
***************************************.

This one -
Is the first ever one of it's type that I have
witnessed first hand - in over 15 years of selling
and installing Amsoil Synthetic Lubricants & filters.

My own shop truck -
In 15 years -
I have changed the AME Marine Diesel 15.40 engine lubricant
and the dual full flow filters

3 times.
**********

3 times without any consequences.
*********************************.

And then - more so that for any other reason -
Because the engine oil filters are mounted
outside on the front angle iron bumper -
an a metal frame of sorts - to show what
the Full Flow Filtration Systems are all about.

Yes.
The engine still runs as well as it ever did ...
IF not better - than when we overhauled it
some 15 years ago.
