Same brew as SuperTech 5/150 All Makes - made by Prestone division of Honeywell. Only the jugs are different. It's a "dexclone" (unlicensed DEX-COOL but dyed green instead of orange and without paying GM to advertise using that name). I'm past 27 months with the SuperTech in my '03 Sonata. Engine ran cool this past summer in inland SoCal with A/C always set to arctic blizzard mode and the coolant is still the same clear green that it went in as. As long as you don't have a leaker, it's a good fit. Otherwise go with traditional silicated "green" or G-05.
