I do not use sea foam in the oil then drive it.
I do the oil changes every 3500-4ooo miles using dino oil then drive it so it is at normal temp,,, then drain all the oil out for about 45 min.. I removed the valve covers because of a leak not one spot of sludge..
I also some times cut open the oil filters. 30 yrs old.
