Supertech ATF +4 is 3.77 a quart at Wally World down here in Tx as of last night.
They were not carrying any "Mopar" brand, but it is all the same. They all have to go through the same tests and use the required basestocks to use the copyrighted name "ATF+4" which is owned by Mopar.
I just bought 4 quarts last night for some work I am going to do on a buddy's van later on today. Might need more than 4 quarts, but I think I have extra in my stash.
