Automotive Fluids You'd Never Use

[67miata]

I have looked at triax for sure. Like Amsoil, I would like to find someone using it and why (not just people selling it). I had one builder who only uses green diamond and then guarantees those granny's for several years....now thats an endorsement. I had never heard of it...I am intrigued,... as I am about trial.

Auto correct....last word triax

Yes still under warranty. You should understand believe Amsoil ULV is a better product, but would like to know more about lubrisity testing ( valve body movements, planetary wear, clutch pack holding/slipping ) etc. Not here to put YOU on the spot, I appreciate your input. Amsoil needs to put more data/videos out there to PROVE to me and others their product is better. They seem to have done it with motor oil....if they stand by their product....convince me it's better and why.

Pretty sure ALL such data is not available to the public, for any ATF. Amsoil mainly relies on fluid LIFE, lack of oxidation and clutch burning/damage. It's not that they haven't published such data on ATF, maybe not in detail as you request. For ATF for sure, I will request for ULV:

Thanks Pablo....appreciate the input

Lucas/ZMax/Seafoam, MOC, I’m skeptical of “universal” ATFs in certain things outside of the Detroit/Toyota/Honda/Nissan/HyunKia spectrum(that’s not a CVT), cheap coolant.

Anything that’s claiming to be universal like coolant or ATF.

I thought this might be an interesting thread. We all have our preferences for products we like and recommend, whether it's because of technical superiority, positive personal experience, or just brand loyalty, but what about those products you'd never want to use?

For me, the first three I can think of are:
-Any multi-vehicle ATF that claims compatibility with both regular automatic transmissions as well as CVTs. I'm not a hater when it comes to multi-vehicle ATF overall, but these magic fluids that supposedly work with both types of transmissions scare me. Yes I know the companies have tested it and tons of people use it, but in my vehicles or a friend or family members vehicle that I care about, absolutely not.
-Any oil additive that thickens the oil. I do think that there could be some merit to some oil additives, but all that super thick stuff like Lucas or Motor Honey etc is nasty. If you want thicker oil, put thicker oil in the car. If you really think you need thicker oil buying a 5W-40 instead of a 5W-30 is a much safer and likely cheaper choice than buying 5W-30 and putting a quart of Lucas or similar product in there.
-Washer fluid that isn't just washer fluid (such as RainX's green one). Not only do some car companies (Tesla) specifically state not to use stuff like that because it can coat the low washer fluid sensor and mess it up, but even on cars without that sensor, every time I have tried that stuff, it makes for a horrible film that causes glare from oncoming headlights when driving at night after using it. Always use the regular one (around here that's typically the blue generic one).

I use glass scrub to get my windshield really clean. I've never had an issue with the orange or green bug rain x cleaners. The yellow Prestone washer fluid is a lifesaver in -20 f winter driving.

Pennzoil. I was driving an air cooled VW with new slugs and jugs (big bore 40 kit!) when it got hot enough to thin the just installed Castrol 30 to the point of the oil light on at idle. Wanting to get the possibly heat damaged oil out, I changed it with Penzoil 30. Pretty much seized it the next afternoon. The Pennzoil didn't hold up as well as the Castrol.

Sounds like a major mechanical problem vs oil issues.
