Robert H. in NY

Today I purchased two cans of Sea Foam engine treatment and one can of the spray. I plan on adding one can to the fuel tank, half a can to my crankcase and then spray the throttle body on my 2014 Silverado 5.3L. My oil is at about 25% now. Would doing all three at once be too much? I know lifter failure on these engines is common so I don’t want to overdo it. I have about 40,000 on the engine.
