I've decided to go for broke and change over to Amsoil SS ATF. What's up with this blue bottle one. Fuel Efficient. Any supposed trade offs to using this vs the red cap. I get suspicious when I read fuel efficient. Makes me suspect there might be a trade off. Both seem to be spec'd for the same vehicles. Just curious before I push the buy now button.

I have never seen a Transmission specked for both Fluids from Amsoil, meaning the regular red 1 and the Blue 1
What Vehicle is this 4?

I plan to use it on my 2018 Ram 1500 8speed zf tranny. According to the amsoil site both qualify for my transmission.

You want the ATL and this is what is called out.

@Pablo I noticed for Jeep ZF9 transmissions you call out two options for ATF fluid but for my 2019 Honda Odyssey with the ZF9 there are no recommendations. Are they not basically the same transmission?
 
The blue cap is a low viscosity fluid equivalent to Mercon LV or Dex 6. The red cap is the older regular viscosity atf like Mercon or Dexron.
It's really not that important. Older specifications such as DEXRON-III required a higher starting viscosity but that was because it also allowed a greater viscosity degradation due to mechanical shear. Later DEXRON-VI started off with a lower initial viscosity but the shear stability is increased, so the reality is that the fluids ended up more or less in the same range after a period of use. People often get hung up on the notion that -VI fluid was thinner and to be avoided when the reality is that in every aspect it is a superior fluid.

If Amsoil says either one will work then either one will work - and will be fine.

What year Jeep? What models? Engines? Examples?

I don't know if the transmissions are identical.

Sometimes Amsoil has not added a recommendation because it has not been fully evaluated.
