Share what you have done recently or lately to your Buick LaCrosse. This can be very informative to take a look at what everyone does to their Buick.

I have a 2017 LaCrosse and I flushed all fluids with these products which are solid, been using them in other vehicles and no problems...

Gotta make the vehicle last, will not be buying any new car soon and I have peace of mind flushing everything out, even the coolant and won't have to worry about it for a while since it is all synthetic stuff. (I saved a bundle as well by not going to the dealer for a complete flush with subpar fluid or who knows whatever they use, not going to be as good as searching for your own stuff).

Next I will be changing the mirrors, hopefully, I can do it myself as they are scratched and dented thanks to my wife.
