Oil change time! Wanted to do front shocks but none of the store here have em..
read up on amazon oil contents and compare that to GTX. I forget where but somewhere on the internet is a website that you can compare oils side by side. I switched over to amazon synthetic in the LS and haven't had any issues yet. The oil is still clean compared, the GTX would have been dark by now.
[edit] found the link today.
