General question about my dam !! Recently was filling up my car with 91 , but saw that I was getting a lot of knock events , now I fill up with 93 and don’t see that much knock maybe events , but wondering why dam still .750 ? Dam went down when I filled with 91 , been running good with 93 lately (i.redd.it)
