No more chirp. I'm currently on Costco 91, which had the chirp before this new one.
Hopefully it's fixed, but I'ma give it a month or so before saying it's fixed.

Remember, you have to get the engine and pump HOT and you have to be running low lubricity fuel, like gasoline with 10% ethanol sold at most pumps in the US. Then you'll know if its chirping or not.
