Hot Shot's Secret オリジナルスティッキング除去剤 32液量オンス ボトル

Works wonderfully and almost immediately on your engine to prevent wear

I put this in my 7.3 but it didn't seem to make much difference in my cold starts which is what everyone recommended. If it does work it only affects start up by a couple degrees at best when cold but I honestly can't say I've noticed any improvement.

Love this

I recommend all Hot Shot Secret products. I have been using them on the last 2 F350s I have had. No engine problems so far. My 2020 has over 500k miles and still runs smooth

Hot Shots Secret is one of the top names in additives and treatments for diesel engines, and gas engines too. I use several of their products, including this one, for years now, and have never had any issues, and after I started using, I've noticed my 6.0l Powerstroke does idle smoother and seems to run better for an engine with 280k miles on it. I use Hot Shots at every oil change.
