pennzoil for 10-15k
M1 for 30-36k.
M1 would be your better value, IMO, and with UOA, you wouldnt be missing anything.

I am from the "more drains" school when it comes to transmissions as cleanliness is next to long life. Drains get out the crud suspended in the oil so I vote for Pennzoil every 15k/or 1 year. Sometimes cheaper IS better.
I'm using the Pennzoil currently in a 1999 Buick LeSabre, and it works. Not much else to add besides that. Oh, it was a dollar more per gallon than the house brand at the local Pep Boys. M1 was around $6/quart, while this Pennzoil was $9/gallon.
Who like's changing there t oil every year?(unless you take it in),,i don't, and do all my own work so i use better fluid and do 40-50,000 OCI...
use the M1 and take it out longer(30k+)...

It took me 45 minutes to change into work clothing, pump out the transmission pan, refill, clean up, drop off the oil, and return. So changing a cheaper fluid every year isn't too bad, IMO.

If you use a fluid extractor it takes about 15 minutes. Way easy.

That would leave way to much old oil behind,the only way is a
line(torque converter)flush with new oil,takes more time sure
but way more effective then repeated pan and fluid drops..

Buy however many quarts the system takes and drain/refill until it's used up. That way you have ~75% new fluid in there, 50% replaced on the first drain, then 25% of the old fluid will come out on the second. And it's way easier than flushing. (I wish I still drove a manual! One big bolt and all the fluid dropped out! Guaranteed new fluid!)
Considering how many people will neglect their automatic transmissions by not changing the fluid ever, we should all pat ourselves on the back for getting new fluid in, whichever way we choose.

True, but an annual drain fill is an easy low cost maintenence regimen.($10) I only flush transmissions that have a serviceable filter and replace the filter at the flush. If that Mazda has no filter and holds 10 qts with 3 coming out at a drain/fill. You can get it to 80% new fluid with 4 drain fills for lass than 1/2 the price of a shop flush. Some manufactirers like Honda call for no flushes but 4 drain fills. Easy for the DIYer who doesn't want to disconnect lines. Many Lexus dealers will only do one drain/fill every 30,000 miles and a flush at 100k. If you do this every 2 or 3 oil changes you will notice your transmission fluid never gets burned. That is the goal.

True too,,but when it comes to my pricy trans to replace, a
"easy low cost maintenence regimen" is not what i'm looking for.
but i hear what your saying PT1.

I think I'm going to pump the pan out again tomorrow and pour in more Pennzoil to get to 75% new fluid, then do it all again in another 30k miles.
Any way the cake is sliced, new fluid is better than old. There's a cheaper way that will get most of the old stuff out, or a much more expensive way guaranteed to get all the old fluid replaced.
