This subject could go into either catigory but I decided to post it in the general topics.

We have no problem deciding which oil to use in our vehicles and it almost doesn't matter unless your engine requires a special oil. Most of us use oil that may be overkill and still change too early. But when it comes to antifreeze and atf we're baffeled because most of us don't want to spend the extra money foolishly on a subpar product that is overpriced. Maybe subpar is the wrong word here but, we seem forced to go to our dealership for the two products(a/f & atf).

We're concerned that if we don't use these correct fluids that we may create costly damage to our vehicles. There never seem to be enough information on a/f and atf so that we can just go to our favorite autoparts store and pick up our favorite or on sale a/f or atf. Brand loyality comes into play here also. Some people want to use Prestone A/F because their father use it for 50 years without issue or, some of us want to use Amsoil, Mobil 1 or RedLine ATF because we want synthetic in our transmissions. But, with all of the concerns about compatibility with the factory fluids and our cooling systems and auto transmissions we either don't replace them or we're forced to go to the dealer and spend. And we also search our brains out here at BOB's or other sites trying to find fluids that are compatible with the factory fluids.

If we weren't concerned about these fluids then the catigories wouldn't exist and, there may be those who know for sure which OTC fluids will/won't work in or vehicles. But Im still concerned about switching to OTC fluids these days in my newer cars. I do it reluctantly and I hate that there seems to be this big secret amongst auto manufactures about antifreeze and atf's, two fluids that I like to keep fresh on a regular basis.

We seem to have oil and filter down to a science for our personal use and what makes us sleep at night but not A/F or ATF. Does anyone feel else the same way ?
 
Yes. It's purely for the dealers/auto manufacturers to make money by making you feel you have to use their products exclusively. Now, we all now the M-M Act in the early 1980's forbids warranty denials due to using OTC parts/fluids. However, there are definitely many applications where the OEM part/fluid is the only sane choice to avoid problems. There are also many applications where if you know what you're doing/buying, you can use the specific OTC product that fits the bill. Example: Global coolant that's silicate/phosphate-free for a lot of cars (OTC), CVT transmission fluid (OEM), the new low-viscosity ATF for some vehicles (OTC).

No.

I use UOAs with ATF & send one to Terry sometimes in an attempt to dial it in further just like I do with oil.

I have also done UCA (used coolant analysis). However, I've only done that once. The change interval is much more of a variable there & could use some debate perhaps. However, analyses could probably solve this "problem" as well.

You could also throw power steering fluid & brake fluid in as well. I'm curious why you didn't mention those as well.
 
You implied but did not mention implicitly that cooling or transmission failures are more likely nowadays than motor issues to total a car.

Since AF and ATF only need changing every year to five years it seems there can be more of a budget to get it right.

The automaker deserves 90% of the blame for omitting trans drain pan plugs and making people open stupid frozen iron-in-aluminum plugs (dodge 2.5) to burp air whenever changing coolant.

Heaven help you find an appropriate coolant if you need to top off "green" silicated in the middle of winter and can't run a 100% water flush to avoid clashing with new "green" of unknown additives.
 
No. I research my products carfuly before I use them. I do not wait for the last minute then try to find a replacement for an OEM fluid. Until the purchase of my 2003 Camry I had never ever used OEM fluids at all. Decided to stay with OEM fluid for my coolant because it made life easier for me and it does not need to be changed as often as I do it any ways. I swap out 1/2 my coolant every spring even though the coolant is supposed to be good for 5 years of 1000,000 miles. If I changed to another type I would have to lose 70lbs. just to reach the drain plug on the backs ide of the block haulf way up our hire a 6 year old to reach it for me!LOL I do not need to flush this way. I just have to drain the rad and res. and refill. Life could only be so easy!Now add in that I do this because I am a nit wit and do not like corrosion and cannot stand the idea of having the same coolant in for 5 years!

Those of us that do not neglect our automatic to the absolutely stupid life time or 100,000 mile fill's that many OEM recomend do not like to pay a premium for sub par fluids just because they have the companies name on them and can only be bought at the dealership. Many of us understand that their are many transmissions that are global and used by other companies then just the OEM that makes them.It is not uncommon to see one transmission in two different applications 8000 miles apart using two different fluids. So this gives us informed owners some choice and allows us to look for alternatives. Their are also a wide vaiety of manufactures out their that want market share and are willing to test their products and make recomendations as to where they can be substittuted in place of OEM fluids. For example Valvoline Maxlife has already told us that it can be used in place of Toyota T-IV and WS so if it can be then why can we not use Dex-VI or Redline D4 or Amsoil or Mobil-1 ATF and so on.......

All of us want the best protection we can get at any give price point if I can get 5 times the oxidation resistance with Dex_VI for $3.79 a quart at Walmart why pay $5 a quart for Toyota T_IV?

Useing aftermarket products makes sense if you are trying to extend the life of the vechile by doing maintence in advance. As to price savings you are reallynot saving much if you are waiting to the last minute to change...Sooner or latter it needed to be cahnged and the OEM price is the price yo use to judge if you saving or not. If you deviate from the planed service scedule then you really cannot compare aples to oranges unles you had planed to change at that same interval witht he oem fluids.

ROFLMAO!!!
 
It is a bigger problem for those of us who distribute and have to stock the products. Since I sell the Antifreeze, ATF's, and all the rest of the oils to the Toyota, Nissan, Mitsubishi, Chrysler, MB, and one of the Suzuki/Chevrolet dealers, I don't hava a problem selecting from my stock when it comes time for my vehicles or putting the same products in customers'cars. But for ATF, the only way to go is with the machine. Drain and fill is a waste. In Tarija we charge an extra $10, but stop the machine, drop the Transmission pan, clean and inspect the filter and all visible parts, then replace it and turn the pump back on.

I have never had any problem at all finding parts-store brands (usually multiple) that meet the specific requirements of my cars. G-05 antifreeze is available in at least 3 brands (Zerex, Mopar, Motorcraft) as is ATF +IV (it was dealer-only for a while when it first came out, as was ATF+III before it, but the aftermarket had it available by the time my first ATF+3 car was old enough to need ATF).

Maybe its different for some other brands, but let's face it: Chrysler has a pretty small market share and if the aftermarket is going to support them that well, it sure will support larger market-segment manufacturers! I just don't see this as a rampant problem at all. Maybe I'm in the minority and just dont' know it.
