I have never hydro locked an engine by pouring SeaFoam directly in the carb or through the brake booster vacuum line.
About 10 years ago I started using Sea Foam in automatic transmissions a few hundred miles before a total bucket flush in the drive way. It will make the ATF go dark. We just did this with the 2010 Subaru Forester that we just picked up with 105K miles. It was up shifting very well but when driving it in manual mode the forced down shifts where delayed then hard. After a few hundred miles I also added Archoil AR9100 to the transmission and now it is shifting better up and down. Yesterday we took a line loose at the transmission cooler and pumped the old out into a bucket by starting the engine until air bubbles appeared then refilled and repeated.
Tonight I put a can of Sea Foam into the gas tank and topped it off.
This Forester is kind of a test bed since I never drove one before and because of their EyeSight system I am interested in a new one. Buying one 8 years old with over 100K miles should let me learn something about Subaru long term quality. Yes I am already in love with it.
While we have been using Archoil 9100 for a while (just ordered and received our 5th gallon) this is the first vehicle to get it in the engine, differentials, auto transmission and power steering.
