Hi

I used regular oil in my new '94 Legacy (back in '94) for the first year, then
switched to synthetic. I currently have about 170,000km (100,000 miles) on the
engine and it still goes like a "bat out of hell". It gets close to redline at
least once a day - helps flush out any carbon buildup ;)

Another good thing about synthetic is that it
lets you know right away when that front
crankshaft oil seal fails :)
 
I have used Mobil1 from 1000 miles to <150,000 miles in a Volvo and a Saab
without ANY problems, oil leaks or otherwise. I now use Mobil 1 (5w30) in my
Forester (62,000 no leak or problem miles) The old idea that synth cause
leaks or leak easier is from 20 years ago when 30 weight oil was the std
summer oil. I use 100% synth as I don't know what percentage of reg oil vs
synth is in the blend. If I was to use a blend I would mix 50% synth with
50% regular oil for the blend. In addition: I would blend my oil from the
same company. i.e. Mobil 1/Mobil/ Valvoline synth/Valvoline etc. eddie
 
The only drawback I can see is the price. My Subarus go 300-400 thousand
with regular oil. If they lasted any longer how would I ever get a new car.
Your Trouper would have diopne just as well on regular oil as well...most
vehicles today will last hundreds of thousands of miles before any OIL
RELATED problems would arise. TG

I hope to get that with mine. I feel better using the syn blend. Maybe it
doesnt matter - maybe it does. To me the small price difference is worth it.
I appreciate all the input.
 
Been using AMSOIL Series 2000 in my 2003 WRX since about 4500 miles. Had an
oil analysis done at about 21000 - Nothing abnormal - could have kept the
oil in longer if I wanted. Changed oil and filter, as recommended by
Amsoil and Subaru.

I got no complaints about Amsoil quality or value. Check it out, see for
yourself.
 
BUT wouldn't you have gotten the same results with the cheapest oil you
could find...$.69-.$99 instead of the $8-$10 per quart for the Amsoil? TG

He definately would have. Where syn's could have an advantage in is
longevity, the twilight years of your engine. Otherwise, if today's engines
were having such trouble using non-syn's at 21,000 miles they would stop
selling them, which obviously isn't the case.

I've found that the majority of people who promote Amsoil and Redline
either sell it, or just perceive them to be advantageous. What percentage
of people keep their cars past 100,000 miles these days as it is? Most are
traded in, and resold, especially people with too much of a disposable
income and buy cars every 2-3 years.

Its the same insecurities that are behind the SUV surge. People want to
feel safe, secure, confident so they waste their money on these behemoths
ignorant to such concepts as physics. In the oil arena, people think they
need to spend the most on the perceived best oil when the generic brands
will suit their usage needs just fine.

there are objective and certain advantages to using synthetic.

i've got a wrx, which i've modded, and i drive it hard... on a daily
basis, at _least_ 5 blasts up to redline under WOT.

the additional film strength, cold start performance, resistance to
coking, etc, are very important to me to spend a little bit extra dosh
three times a year, especially in an engine that gets >130bhp per
liter.

as to whether or not the high end syns have an advantage, to that i
cannot comment, since i have no first hand experience. i suspect the
same may be true for many other posters in this thread.

using mobil 1 100% synthetic 5-30 on my 2000 OBS - have since the
second oil change (i think there is a break in period). i'm hoping
that it will keep my car in tip top shape (so far so good), add to the
resale value and allow me to change my oil less frequently (6K). with
the amount i drive, i'd be in changing my oil monthly, and that bites!
(don't have a garage, or driveway to do it myself).
 
Been using Mobile One in my 00 OB and not a problem in 60K Miles. The
reason I use it in this car is that this Subie gets started and run about 3
miles at a time and it's mostly side street, hill driving. I'm trying to
reduce that initial startup wear and get more miles out of the engine. If
this car were driven much on the freeway, I probably wouldn't bother with
synthetic. I have lost two cars engines prematurely due to this type of
driving and I didn't want to do it again...Jim
 
I also use Amsoil, I am a dealer, thats the way to get the best price.
There are people out there that always jump on the Amsoil people for
some reason. What about all the Mobil 1 people, maybe they sell Mobil
products or own a oil distributorship for Mobil. (or Castrol,or
Valvoline)

Big oil fears the little guys like Amsoil and Redline. Amsoil clearly
outperforms, they put the figures in writing and are they contested by
the others ? They have never challenged the facts.

Just get tired of all the jealous Amsoil haters out there.

Hi,

I'm NOT a jealous Amsoil hater--used it for a while ~25 years ago when a
coworker was a dealer. However, though I don't have a testing lab or
anything fancier than my log books to look at, I could see NO
improvement (gas mileage, lower oil consumption, obvious engine wear)
using Amsoil over the Castrol GTX I've used in most of my vehicles that
warranted the extra cost. (I repeated the "test" several years later in
a different vehicle with Mobil 1--same conclusion.) My Subie has lived
on dino oil its whole life, and now, at 344k miles, it's getting tired.
Over that lifetime, the difference in price between Amsoil (or some
other synthetics) and dino oil just about equals the price of a rebuilt
engine. Nobody has been able to show me that my engine would have still
been in great shape at this mileage with synthetics, be they Amsoil,
Redline, Mobil 1 or others or that my overall cost per mile would go
down. In fairness to the synthetics, I've never started right off with
them--my "experiments" were with engines that had lots of dino oil miles
on them first.

I'm not arguing synthetics are NOT good, just that, for me, they don't
show themselves to be cost effective. But I live in SoCal, where it
doesn't get really cold (does get HOT, though) and close to 85% of the
25k to 30k miles I put on most years is freeway driving, so I'm sure I'm
not stressing things the same way a guy in New England or eastern Canada
who drives mainly short distances (especially in winter) all the time
might. YMMV, of course.

I'm not jealous. I just enjoy watching the small followings that Amsoil and
Redline have and how its kept its small followings all these years. They
pass themselves off as a "better" oil, and yet have never grown in market
share. If they were indeed "better" they would have continually grown, like
every other dino oil has over the years, and overtaken the superiority of
the "lesser" dino oil producers as they like to view them.

There's alot to be said for staying grass roots and keeping your prices
higher. You're perceived, by the ignorant, as the better product because
you cost more and are harder to obtain. This myth perpetuates as more and
more folks who are no more knowledgable than the person who recommended it
to them buy it.

This is the reason you rarely see people defending them, other than
distributors who have all the marketing propaganda to respond with. The
people who do respond tend to be clueless as to what exactly the oil is
doing better for their engine and are from the "i dunno, i just know its
better DoOd" variety.
 
Used Quaker State full synth 5W-30 in my 96 Subaru Legacy with no problems.
Now using the same oil in my '04 Forester XT.

The reason most people have not changed over to synthetics is because
of the cost factor. Most people look for the cheapest method in car
service (and alot of other things), so synthetics will not get a look
in no matter how good it is. This is why they will never "grow" in
market share. Having said that, BMW and Porsche recommend synthetics
in their cars, partly because of extended drain intervals.

Dino oils generally perform adequately for most uses in cars
especially those folk who drive their cars for long periods in a day
and let the car warm up correctly. This allows the oil to boil off the
condensation that develops in the first few minutes of start up from
cold. If the condensation isn't boiled off, then the water can
chemically react with impurities such as, but not limited to sulphur
(petrol by product) and lead to formation of sulphuric acid which as
we all know eats away at metal etc (not good for a motor). Synthetics
have been shown to protect against these impurities as the oil itself
clings to the metal better(especially diester based synthetics) and
thus keeping a film against metal parts. Synthetics are also less
affected by these acids.

So, as for your "ignorant" comment, you really should check the facts
on synthetics before you make such a statement. Synthetics ARE better
(proven generally) and to some worth the extra cost but this doesn't
make synthetic users ignorant, on the contrary, they just spend more
on a better product. Ther anr many advantages to synthetics and too
many here to list, so, you'll have to look it up yourself. "Bobs the
oil guy" is a good place to start.

Frankly, I don't care what oil you use and if you think a dino oil is
adequate for your car, then goody for you, but I like the "peace of
mind" that a good synthetic oil gives me. Kind of like the "peace of
mind" knowing that I have awd or abs brakes on my Subaru. I may never
NEED them but its nice to know they're there and hopefully work when
and if I need them. There will be people from "either side of the
fence" regarding oils, and if you feel superior for saving a few cents
a mile on oil cost, then good. I feel better for knowing that the
synthetic oil is better for my motor.

I am not a dealer but I do use synthetics (either Neo or Amsoil) and I
have my oil checked periodically with an oil analysis co. They state
that the oil is outperforming mineral oil at the same mileage mark as
borne out by the very low impurities, metal from engine internals,
acids, gums and varnish build up. I generally change at 10,000 miles
but the analysis states that I could double that drain period as long
as I change the oil filter at the manufacturers recommended period.
 
Every year National Oil & Lube News conducts its Mobile Lube Survey to
determine patterns in Advertising, operations and sales. Survey results
indicate that synthetic motor oils are popular in the mobile lube
market, with 73 percent of operators offering them. Amsoil already has
a significant presence, registering as the thir best-selling synthetic
in the mobile lube market.
Amsoil also competes in many markets . Snowmobile magazine survey's are
showing it to be one of the top oils. Motocross Action magazine
indicated the Amsoil is now the #1 non-factory synthetic 2-cycle for all
motorcycles. The fact is Amsoil is growing but it still has a ways to
go to compete with big oils size and political strengh.

Over the next five years,demands for lubricants offering improved fuel
economy, reduced emissions and estended drain intervals will steadily
grow, signaling the demise of conventional Group 1 base stocks (dino
oils) while higher Group 2, Group2+, Group 3, and Group 4 (Synthetic)
base stock will prosper.
The most recent ILSAC GF-4 pasenger car motor oil specs will introduce
in July, but discussions is already underway for the ILSAC GF-5 upgrade,
targeted for 2007 or 2008 release. The upgrade will drive Group 1 base
stock demand toward Group 2 while also shifting Group 2 volumes to
Group2+ and Group 3.

Dino's days are numbered as we know them now.
