Ok. I have finally accepted a 5k OCI after decades of 3k. BUT, I can not get my head wrapped around leaving the FF coolant in my MDX for 100k/10 years. My last two cars both used Toyota Red Long Life (not the pink extended life). I always did a d/f every 2 years (about 10-12k miles for us)and the cooling system/coolant stayed pristine.
One question I can't find the answer to is why Honda Type 2 Blue coolant FF is good for 10 years but then needs to be changed every 5 years.
Having said all of that, how long should I wait before doing my first d/f? Thanks.
