Re: Cackle and BIOD
I was never sure what the "cackle" sound was but mine sure got louder when the stations started selling the winter mix. 10 minutes after adding my first three gallons of bio, the engine was noticably quieter. My son noticed the sound reduction the next weekend when the mix was around 70%.
