Can you "feel" a difference after a regular oil change?

er, yes they have. that's why they have "economy" branded blends.

of course, because amsoil marketeers are ****-heads, that means all the
technology of all other companies is bogus!

but you just said that there's no such thing as better economy. you
/do/ know that economy and viscosity, what affects cold starting, are
related don't you??? oh, wait, maybe you didn't.

yup. and remaining fiercely ignorant is a fabulous way to go through life.

 

They don't? Look here: <http://www.mobiloil.com/USA-English/MotorOil/

Actually, if there is less friction, there is better fuel economy.

And to meet the oil standards set by the API, the oil has to save
fuel. And, the engine will last longer.

Overall, though, the savings are small and only a small percentage of
people will actually have their cars long enough to benefit from a
longer-lasting engine. Most people sell their cars well before this or
the cars have other problems, like that a crash, that ends the service
of the car.

Whoa!
You do what? I hope you are not using used oil to kill weeds.
That is against the law for sure and BAD thing to do for the environment.

 

Hmmm,
They can unless being dumb. Just watch the tach.

 

have you ever been to la brea tar pits?

 

Hi,
Then you must be so called motor vehicle operator, not a driver.

 

Hmmm,
I don't live my life based on some one's claim.

 

Hi,
Have you been to oil sand tiling pond?

 

They only claim the increased fuel economy for 0W20 and 0W30. Yeah,
since it's not possible to make a 0W20 or 0W30 with petroleum base
stock, they have a point there. But even for the "Advanced Fuel Economy"
products, they keep going back to "during warm up" every time they make
a claim of reduced friction or "saving" energy.

"During warm-up, Mobil 1 Advanced Fuel Economy flows faster because of
its lower viscosity to minimize metal to metal contact to reduce
friction and wear."

"During the warm up phase, the Mobil 1 fully synthetic formulation
because of its lower viscosity flows more easily through the oil pump,
requiring less energy to pump the oil to the critical engine parts."

"http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_Advanced_Fuel_Economy.aspx"

But for their "regular" synthetic oil, 5W20 and 5W30, they make no
claims of increased fuel economy.

 

no, but i've been to the tar pits and they're rank. my point is, while
i don't think it's a good idea to wantonly spread oil anywhere, nature
does a pretty good job of spreading that stuff about on its own.

 

you're confused dude. badly confused.

see above.

Are you going to keep backtracking?

No offense, but you need to learn to read for comprehension. Nowhere do
they make a claim on that page that their 5W20 synthetic base stock
product provides better fuel economy that a comparable 5W20 petroleum
base stock product.

Why don't you show a _single_ independent study that shows a benefit to
most people. Oh, wait, they're aren't any!

After all these years you'd think that there would be at least one
published study that showed a provable benefit in terms of wear, MPG, or
extended change intervals for synthetics uses in non-high performance
engines, operated in moderate climates. But there aren't _any_. There's
anecdotes by users of synthetics, there's claims by companies like
Amsoil which have never been validated, and of course various claims by
MLM people selling Amsoil. Just choose your benefit from one of the
hundreds of MLM web sites!

Of course there probably have been plenty of studies that were done but
not published because they didn't have the results that the company
paying for the study wanted.

It's amusing that not even Mobil, who would have the most to gain by
some evidence of increased fuel economy for synthetics, can make that
claim. All we see is a heavily qualified statement that logically makes
no sense:

"Actual savings are dependent upon vehicle/engine type, outside
temperature, driving conditions, adjusting tire pressure, and your
current engine oil viscosity."

Huh? So adjusting tire pressure affects how well synthetic oil works (as
opposed to how well dino oil performs, LOL). And how does your current
oil viscosity, if it's the same as the viscosity of the synthetic, make
any difference.

So here's what Mobil thinks you should do:

1. Change to a lower viscosity of synthetic base stock oil than the
petroleum base stock oil that you're currently using

2. Drive only in extremely cold temperatures where sythetic has a
benefit at start-up.

3. Adjust your tire pressure, from the previously under-inflated
pressure you had with your petroleum base stock oil, to the proper pressure.

Geez, some people are gullible.

STOOOOPID.

 

Tire pressure affects fuel economy.

If you change from 10W30 regular to 5W20 synthetic vs. changing from
2W20 regular to 5W20 synthetic, you will have a different change in
fuel economy.

Where did they say that?

And some people are just plain stupid. You have GW Bush disease.

 

Far as I'm concerned, SMS is a long-haired maggot-infested dope-smoking FM
type. If he was called to give professional testimony, as a judge, I'd have
the whole thing stricken from the record as being unreliable.

IMO, it's their imagination. I've never noticed anything, unless I had
something else adjusted along with the oil change.

Of course it does, but Mobil is being disingenuous when they claim that
tire pressure has an effect on how well their synthetic base stock oil
performs versus how well a petroleum base stock oil performs. It makes
no difference. You should keep your tires properly inflated no matter
which type of oil you use.

And if you change from 10W30 petroleum base stock to 5W20 petroleum base
stock you'll see the same change in fuel economy. Of course you should
not make that change no matter which base stock you're using, but that's
another matter entirely.

Mobil is trying to get people to change multiple variables at the same
time, one of them being the base stock of the oil, then claiming the
increased fuel economy from switching to a lower viscosity oil and
proper tire pressure is due to the change in the base stock.

Even for their "Advanced Fuel Economy" formulation, the increase in MPG
isn't due to the base stock being synthetic, except for the fact that
apparently it's not practical to make a petroleum base stock 0Wxx oil.
Even then, they're hedging their bets, admitting that the advantage is
during start-up, not during normal operation.

 

dude, you have a serious reading comprehension problem.

see above. quit while you're behind.
