Lifters very audible at startup. Using full synthetic 5w30 either mobile1 or royal purple. Engine has 178k mostly highway miles. Running xDelete enabled so its a rear wheel drive with a 6 speed manual trans. Should I change weights and go with a 20w50 synthetic, or is that too heavy for propper circulation to the valve train? Thank you for your time and valuable input!
