Really fun reading your Echo adventures
I also have an Echo with an AMSOil BMK 13 remote oil kit. Normal Echo is ~3.3 quarts of oil & with this kit I'm at 6.3 quarts. I was just thinking that the extra oil capcity might be a good way to keep engine temps down? I really don't know for sure but I can say I don't ever remember hearing my fan go on?
Anyway just a thought..
