Many of the tuners I know all say to stay away from Costco fuel. My good friend also had a bunch of knock activity on his knock sensors (Turbo E46 on an Infinity Standalone) which had previously been fine...I asked if he filled up at Arco...he said Costco...so there you have it. Shell for this guy.
