Transmission fluid evolution..

Toyota like so many other manufacturers is using 'sealed' transmissions with fluid that supposedly never requires/requires infrequent changing. With the 2018 Camry 2.5L engine, the factory fill motor oil is now 0w-16 (and per the manual is the ONLY oil to be used unless you can't find 0w-16, which is just appearing in the US market). Hard to wrap my head around, but Toyota has been using 0w-16 on its Japanese vehicles for 2 decades. Guess we'll see how it plays out, especially driving in Florida in the summer months.

My old burb was designed for Dex III. I have of course been using Dex-6 on the occasional drain and fill. I went to the store to buy some Dex 6 the other day and all they had was a synthetic Dex-6/Merc-LV. I read the label and it reads like a fluid that replaces the above two plus some import fluids. I suppose I will run it and not worry about it. But, as a general rule, I haven't been a big fan of the multi use fluids.

probably does not matter at this point but dex 6 was not backwards compatible with dex 3 at least not in the Allison transmissions dex 6 would damage the seals for some reason there was a certain manufacturer date for the change over, look for the material standard number if it is on the bottle it should be ok .

Lubricants continue to improve on regular basis. It is one of the reasons cars go 200,000 miles now and often much longer.

Definition - Multi-use - works well in all equipment except for things that I own. :D
