Whats thoughts on switching to Amsoil in 91 7.3 idi truck? Good? Bad? Going to cause oil leaks?
I agree. Any oil will get contaminated and need to be changed. Unless you add an oil bypass filter setup.My thoughts are it's a complete waste of money. The soot builds up in the oil and it'll need to be changed long before the oil breaks down.
