2005 Ford Escape 260,000 miles. i am not the best with cars and used Sea Foam as directed on the label when i did a cleansing oil change and after running 12 new quarts of oil through the system my SUV showed the oil pressure light and heard the engine knock. i immediately turned off the engine waited and restarted after and it ran good a few seconds then knocked and i turned it off. apparently cleaned inside of sludge--is there a way to flush the oil system?
Did you use 1 ounce per quart of oil? Seafoam is a chemical additive designed to be used on two cycle outboard motors.
yep, already sounds bad...i added 5 oz to the jug i used to mix it to the container that first round yes
As @doc says Seafoam was formulated to be used in old-school 2-cycle outboard motors, it should not be used in a modern automotive engine.
Unfortunately if the engine is knocking the damage is already done and it's unlikely that further oil changes will help.
used Sea Foam as directed on the label
which Sea Foam product did you use? and why?
to clean the sludge and deposits. i bought Sea Foam Motor Treatment 16 ozfor cars boats fleet
How do you know you had sludge and deposits?
