suprz, is it ok to use Seafoam in the oil?? It seems like that would mess with the viscosity, which would reduce the ability of the oil to lubricate moving parts.
But I am, once again, revealing my ignorance -- I really know nothing about the chemistry of engine oils.
In small amounts it would be. It would be run with the oil to loosen up any sludge, and built up carbon. I would only run it in an engine that I knew was on the way out to see if it helped. Like that YouTube person, his hydraulic lifters were probably sludged up and they weren't getting enough oil up to the top of the engine and causing the lifter tick. Seafoam being basically thinner with some cleaning characteristics would liquify the sludge allowing the oil to get to the lifters etc.. I would not run it in the oil for an extended time, and change the oil soon after using it
