Mobile 1 Extended Performance
 
I have been using Mobile 1 Synthetic Oil for years & was pleased to hear
about the introduction of Mobile 1 Extended Performance Synthetic. What I
found disturbing was that it does not meet API ILSAC GF-4 Certification
while Castrol Syntec does. I believe Mobile 1 SuperSyn does meet these
specs. At any rate can you tell me the reason for this?

I am considering Castrol Syntec a try for my next change which does meet
the GF-4 specs.

Or does it not really make that much difference?

2001 Jeep Wrangler Sport 4L 6 cyl w/ 23K miles & I have been pleased w/ the
performance of Mobile 1. The manual calls for 10W30 oil.

Thank you,
Campbell C Freeman

In the words of Jeff Strickland... "snake oil" & extended performance "snake
oil".

IMO, if you change the oil and filter regularly, the oil you use makes no
difference.

Re: Mobile 1 Extended Performance
 
and anyway... what do you mean "I have been pleased with the performance of
Mobile 1"? Do you have the used oil tested after removal? Does it make the
Jeep run better? Or what?

Nice to have such positive comments.

I never said or implied that the oil I was/am using is "invincible." I just
made the comment that I have been pleased with it (Mobile1).

I think I will just take a break from the group. Too much negativity.

Did you even see or read the "disclaimer?" <"Or does it not really make
that much difference?">


You ask a simple question or make a comment and you get blasted. I see it
over and over and over again. I thought the purpose of the newsgroup was to
be helpful, give and offer advice, and ask questions.

Guess I just don't get it.

I regret even having made the original post.

Re: Mobile 1 Extended Performance
 
Sorry man but the last person I know to make claims about how long
between oil changes 'he' could go ended up with the oil pressure
'mysteriously' pegged out and upon inspection we found 6" of solid black
goo inside his oil pan....

He then promptly sold the truck to some unsuspecting fool while still
making 'great' oil comments....

Oh, I think if you look, the castrol is 'fake' synthetic, (could be
wrong there) with a high price because of the name not the original
synthetic like Mobile uses in 'some' of it's oils.

The oil companies made the word 'synthetic' a buzz word that actually
only means it costs more, nothing else. They took the 'real'
'synthetic' oil makers to court over the definition and won.

Re: Mobile 1 Extended Performance
 
Sorry man but the last person I know to make claims about how long
between oil changes 'he' could go ended up with the oil pressure
'mysteriously' pegged out and upon inspection we found 6" of solid black
goo inside his oil pan....

He then promptly sold the truck to some unsuspecting fool while still
making 'great' oil comments....

Oh, I think if you look, the castrol is 'fake' synthetic, (could be
wrong there) with a high price because of the name not the original
synthetic like Mobile uses in 'some' of it's oils.

The oil companies made the word 'synthetic' a buzz word that actually
only means it costs more, nothing else. They took the 'real'
'synthetic' oil makers to court over the definition and won.

Re: Mobile 1 Extended Performance
 
Well...again I ask "...did you even read my original post...?" I never said
anything about "...how long (I) could go between oil changes..." OR about
the so-called "invincibility" to which you refer, but I have already
commented about that.

BTW...both Castrol Syntec & Mobile1 are fully synthetic oils, as are Red
Line and Amsoil.

I do use synthetic and I am not ashamed to do so. My Jeep Wrangler Sport is
a 2001 (bought new in May 2001), and only has 23,000 miles. I never go past
3 - 3.5 K on the "oil." This averages to under 20 miles a day
(roughly)...98% city driving...which means I can go up to 6 months between
oil changes. That is one of the reasons why I use synthetic oil. It is
also my choice to do so...like it or not...agree with it or not.

I give up. Please disregard my original post entirely.

Campbell Freeman

And thanks Jerry Bransford. I always appreciate your posts, knowledge,
measured approach, and advice.

No problem.

I'm just a 50 year old guy in SC who has wanted a Jeep since he was a child,
playing "Army." Now I finally have one...a "real" one (boy, that will
likely start it up again), and I love it, and I want to keep it as long as I
can.

And who knows, I may get "run over by a bus" on the way home today. I hope
not, but if I do, then none of this will have mattered anyway...

Thanks,

Hi Campbell,

The main claim of the new Mobil One Extended Performance is the longer
15,000 mile service interval. Looks like they're trying to answer to
AMSOIL's extended service claims (35,000 miles!):

http://www.worldsbestoil.ca/0w30-ams...ne-engines.php

As for the Castrol Syntec, be careful. Apparently the US-made version is
not a 'true' synthetic and is a relatively poor performer. Look for the
imported Castrol Syntec with 'Made in Germany' printed on the bottle.

Myself, I change the non-synthetic 5W-30 in my high-mileage 4.0L every
3K miles. The engine runs great and it doesn't burn oil.

Re: Mobile 1 Extended Performance
 
My $0.000002...

I have had the opportunity to study quite a lot of closely held
oil/filter/wear information. Here's the basics:

Keeping oil clean is the primary goal. What is 'clean'? The primary
component of 'clean' is particulate loading and particulate size. Your
normal paper oil filter filters out most of the particulates 25 microns and
larger. That's 0.001 inches. The smaller chunks keep circulating. Think
about a low viscosity slurry of oil and rubbing compound.

As the total particulate loading is reduced and the maximum size is reduced
by more efficient filtration, the total amount of component wear starts
dropping rapidly. Cutting the load and maximum size of particulates in half
results cutting the total wear by a square root function. There is also the
distinct probability that any single element pleated paper filter will be
leaking unfiltered oil (blow-through) by 3K-5K miles.

The other thing that happens is that the additives and stabilizers in the
oil are depleted and there is an associated breakdown of the polymer
molecules. However, I am aware of an experiment that ran petroleum oil with
double efficiency filtration that ran 30K miles while maintaining the oil
within all oil testing specifications.

Another factor is the contamination of oil with other liquids - fuel or
coolant - that serves to reduce viscosity and upset/reduce the additives,
breakdown the oil and drastically accelerate wear.

A true synthetic (Mobil 1 and many others) does not breakdown like pure
petroleum products. But, it can get just as dirty.

In a perfect world, using a premium lower-micron rated filter and changing
it frequently can allow a synthetic oil to be used over and over for many
miles and still maintain minimal total wear. The cost of using synthetic
oil is the oil, not the filter. Premium filters generally cost around $10.

Clean oil = low wear.
