Hello, I just purchased my EVO 8 last month and looking to do some maintenace work. I know the tranny is 3 quarts I was going to go for BG sync but I hear from alot of people go Gm SyncMesh. Also slowboy racing told me to do a heavy oil for the rear diff like red line? what weight do I use and how many quarts? and for the front transfer case should I use bg or gm and again how much oil do I need? thank's for any info and help.
