My Sonata makes a rattling sound when accelerating, usually at lower RPMs with heavier throttle. Kiind of like a pennies in a can sound, hard to explain. I've noticed when I run 91 octane in it it doesn't make the rattle sound, and always starts back up with a fresh tank of 87.
I run a bottle of Techron every 4-5k miles or so, with 87 octane and Techron in the tank it still make the noise. I usually use Costco gas but last fill up was Shell and it pings too (87).
Does it matter that it pings? Is it hurting anything?
Should i just run premium or would it be better to add an additive?
Thanks.
