dont think the jury is out yet on the new orange antifreeze but it is very controversial.i put it in mine this fall but then i heard the rumors so i have my doubts now.i dont think a big company like prestone would put it on the market without thorough testing but you never know it this day and age.the only real test is out on the road and not in the lab.i am going to keep a very close eye on mine and if it starts to turn colors, i will probably dump it.i dont know what volvo oem antifreeze is but it sure seems to give out heat quicker than anything else on the market.
