The garage that changes my oil uses NAPA brand oil.
The mechanic is pretty adamant about this,
and insists its "good stuff".
I guess I think of it as "lowest bidder" repakaged oil.
Should I find another garage ?
I know that oil preference is as personal as beer brands.
but I need an opinion;
I don't want to use a synthetic oil.....
( I still believe in the 3000 mile change )
I've heard many reccomendations for MOBIL brand oil.
Can anyone provide some facts ?
Or are all oils pretty much the same.
I personally use a blend of diesel 10W30 and 15W40 in everything I drive.
It's thick stuff, but guarantees almost no engine wear and has higher
detergent quantities than most regular oils. What converted me was getting
an 87 Colony Park through an Ontario emissions test, after its engine had
seized because the owner drove it without coolant or oil for over a month,
with a single digit hydrocarbon reading. It can maintain oil pressure with
almost nothing in the crankcase.
I still change about every 5000kms.
Except that I'm not selling anything, and it seems to work. The reasoning is
this: Ever notice how diesel oil always seems to cost $2-3 more than premium
synthetic in 4L jugs? Ever looked at what a harsh environment a diesel
combustion chamber is, in comparison with a gas one? Since diesel oil does
the same thing as "regular" oil, ever wonder what they're putting into it to
justify the extra expense? Maybe you should do some *actual research* (I
know, it involves reading - such a drag) before you go around screaming
"Fraud!". As with all things though, caveat emptor.
Ironically, I was set on to this in the Cadillac newsgroup a few years ago.
Did I say insufficient oil anywhere? I said "It can maintain oil pressure
with almost nothing in the crankcase" which does not specify a quantity,
sufficient or insufficient. I'll do that now: Approximately 2-2.5L, half of
what it's supposed to hold.
If you have anything constructive to say, remember to remove the boot from
your mouth before you try to talk.
PS. The wagon's still on the road, and up to straight SAE 50 dumptruck oil -
fun to start in the winter, I imagine.
That's quite a change.... from "almost nothing" to half full. You'd make a
good car salesman....if all your customers were fool enough to take you at
I don't know where you buy your oil, but around here premium synthetic is
double the cost of mineral based diesel oil. Shell Rotella T is a good
A quick search on the web shows Mobil 1 at $19.80 a gallon and Rotella T at
$11.99 a gallon. This *should* help to show you how full of crap you really

Yes, I've been working on them for more than 30 years. But since the oil
hopefully doesn't get into the combustion chamber, I don't see how that
furthers your argument.
Since you consider a half full crankcase "almost nothing", can I assume the
owner only drove it a block or two during that month?
If you're ever in the market for some ocean front property, let me know.

No offense, but where I come from, half full IS almost nothing when we're
talking about engine oil. What do you do when you see the oil light come on?
Drive another 30,000kms?You'd generate a lot of business fixing people's
cars if you told them to drive half empty everywhere. What's the next plan?
Fill 'er up with sand?
I'll give you a hint, Einstein: Ping! Or lack thereof.
The fact that you've been allowed to work on cars for as long as 30 years
astounds me. You sound like a real butcher. And oil DOES get into the
combustion chamber when an engine's got a bit of wear (the infamous blue
cloud on startup) or has damaged cylinder walls/piston rings, like the
Colony Park, from seizing.
No offense taken, but where I come from, half full is half full. Or half
empty, whichever you prefer. To say that it had almost no oil in it would be
a gross exaggeration bordering on a lie. Just like your statement about the
vehicle being driven more than a month with NO oil and NO water. You are
either very gullible, or a liar.
What do you do when you see the oil light come on?
Where did I say it was ok to run an engine half full of oil? I only pointed
out the distinction between "almost nothing" and half full.
What's the next plan?
I'm finding it difficult getting down to your intellectual level. You're
going to have to spell it out for me.
You really should work on your reading and comprehension skills. I didn't
say that I worked on cars....or trucks, for that matter.
You sound like a real butcher. And oil DOES get into the
And quite frankly, no offense meant, but why the fuck are you going on about
this anyway? You certainly aren't going to browbeat me into changing my
thinking. I was sharing a personal experience, and you took it as a
commercial like those turbine things that you put into an air cleaner for
better fuel economy. As I said, I'm not selling anything, and you're only
interested in being a troll. What point are you arguing right now? Whether
half empty is almost nothing, without any context at all. You might be
happier here: alt.philosophy.objectivism
Context is everything, genius. In the case of a glass of water, I agree, but
in the case of a car, get a clue. The oil light has been on for awhile in a
car half full.
That's because you're looking in the wrong direction. Try looking up, and
checking out some basic chemistry, like specific gravities of substances,
surface tension, bonding, behavior of basic organic molecules, like
detergents, and other fun stuff. You know, that applied science stuff that
you didn't take when you didn't go to University.
I'm not going to even bother with a mouth-breathing simian like you. This
discussion is over.
I have always used the cheapest name brand or store brand stuff
I can find. All of my vehicles (>10) have gone at least 250,000 miles
before trade in, still running strong but bodies developing cracks.
Never had an oil burner. Never had a bad engine.
Almost 275,000 miles using regular OL' Castrol or Penzoil 10 w 30 every
Sometimes in the winter I may use 5 w 30 if its going to be under 30
As of December 2002 the car has had 75 oil changes. I got to add up 2003
total next month.
