@jpetrol251 I think you meant to post your questions in the below thread......
FunnyI have 2 GNXs and a bunch of other cars worth more than either and do all my own maintenance because I enjoy it
I use vr1 in my 9 second GN and both GNX 10w30
I change it every 6-12 M
Vr1 had zinc etc in it
I used to use penzoil 10w30 and add zddp and had no issues either
Again many ways to get it done and many opinions
Also change it yearly even if it doesn't move
