hello, guys! new here on BITOG. what would be your advice? i've got a 2006 Grand Cherokee HEMI V8 Overland running on 5W-20 dino, has less than 1000 miles. would it be okay to switch to full synthetic before 3K? what would be the best 5W-20 full synthetic in your opinion? should i add LC or VSOT or low dose (3oz according to a-rx website)of A-RX right away? replies are greatly appreciated. thanks.
