I know exactly what the links said.
It's someone else who said the links didn't say what I said they said.

I'm not a believer in bull**** as you can probably tell by now.

First link says:
keep things simple by changing your oil filter every time

Nothing wrong with replacing your oil & filter every day of the week.
That's why I said it's OK whatever schedule others used.

Alls I said was the manufacturers often recommend every other interval.
Those who refuted that fact didn't produce a single reference.

I produced five.
Alls I'm saying is you can replace your filter on any schedule you like.

But don't claim manufacturers don't recommend every other oil change.
Everyone who claimed that so far has pulled it out of their asses.

That's all I'm saying. You do what you want. I do what I want.
I follow what the manufacturer recommends.
(1) I choose good oil (lasts longer than the manufacturers recommendation)
(2) I choose good filters (they last longer than the oil change interval)

Second link says:
Many manufacturers say to change the oil filter every other oil change.

Of course it says that.
It says what I said it said even though some dufus said it didn't say that.

Alls people are doing is pulling out recommendations from their own ass.
Nobody but me has supplied any references from manufacturers & manuals.

You do what you want to do.
I will continue to follow the manufacturers recommendation.
And I will continue to choose the best oil and oil filters I can figure out.

The only thing new to me is the huge number of synthetic oil specs.
I don't know how to choose a good synthetic oil yet.

There are too many specs to try to figure out at this point.
ACEA A1/B1, A5/B5, A3/B4 A5/B5-10, A5/B5-12
API SN, SN Plus, SN-RC, SM, SL, SP
BMW LL-01, LL-04
Chrysler MS 6395
FIAT 9.55535-H2, FIAT 9.55535-M2, FIAT 9.55535-N2
Ford WSS-M2C153-H, WSS-M2C929-A, WSS-M2C930-A, WSS-M2C945-A, WSS-M2C946-A, WSS-M2C947-A
GM-Opel LL B-025
GM 4718M, 6094M, LL-A-025, dexos1 Gen 2, Gen 3
Honda HTO-06
ILSAC GF-5, GF-4, GF-3
MB-Approval 229.5
Porsche A40
Renault RN0700, RN0710
VW 502 00 - 505 00

many of them the same people who would never go past 3,000 miles
would never dream of doing an oil change without also changing the filter.

Like I said many times before you do what you want to do with your oil.

But don't tell me my references don't say what I knows they say.
I didn't post the references without reading them first.

You alls pulled out everything you said from your own asses.

Why pass brand-new, clean oil through

That's OK.
But what you pulled out of your asses is not what my manuals say.

I just follow my manual that says every change.
If yours differs, fine, follow it.

Just don't tell me my service manual don't say what I knows it says.
Everything most of you said you pulled out of your asses.

I'm not a believer in bull**** as you can probably tell by now.

Yet I'm new to buying synthetic at ~$2.50/qt so alls I want to know now
is how to tell the difference for sure between any two synthetics.

Does anyone here know how to tell one synthetic from another?
