Hey guys
Getting mixed opinions from my local mechanics. Want to try and ask here..................
So I scored some old stock Valvoline nextgen conventional 5W/10W30 at a AAP hub and was wondering if this is safe to use in my Tahoe ?? Not sure how they are but bottles were turning yellow from sitting on top shelf near the over head lighting lol
At moment I have a 2002 Tahoe 5.3 with over 300K and some moderate lifter noise. So not sure if its safe to use or go with my gut choice of my stash of Castrol GTX 10W40 ??
