Hey Folks, I was wondering if anyone has tried or can reccomend an engine flush product that can be used prior to oil change, I am shortly going to change my oil and thought it may be a good idea? Ive seen the Wynns product around but you never know about the authenticity of the benifits these products claim to deliver! Also has anyone used Castrols Edge 5w 30 on there LC 20V T? If so what do you think?
