Can you mix the 2? My 2012 KK has 5 year (68048953AC) in it now, I may be able to get some 10 year for free...

The more i am reading, it seems that 5 year is HOAT, and in 2012 they started using 10 year, which is OAT, which i just confirmed by reading the bottle. I will take it anyways, because we also have a 2018 JL.....

I was really just thinking in case i had to top off. I replaced my water pump yesterday and used the 5 year HOAT, which i have plenty of.
