You are corrent DEX III is not a synthetic ATF, I believe the DEX VI is and it is much more expensive. Valvoline Maxlife ATF maybe compatible with Red-1, I will have confirmation or denial tomorrow.The only information I was able to gather is that Dextron III is formulated using a Group II basestock. Granted that this is correct, Dextron III is therefore not a synthetic ATF. I could not gather any information about Apoll Oil ATF Red-1 ATF. I'm afraid this isn't much help. :blush:
Interesting. As KIA's own USA tech support site tells KIA MECH's thatKia Red-1 is the only fluid you can use on the '05 Sorento. I haven't heard of the Mobile stuff, but it doesn't surprise me that it has come to exist. Kia Red-1 only works on one car, the '05 Sorento; no years before, and no other models. All of the other new models take Mitsubishi Diamond ATF-SPIII, which isn't any cheaper.
