Probably a little cheaper as this stuff is not cheap to begin with. You just spray it on your engine while it is cool. Let it sit for a couple of minutes. Then just thoroughly rinse with a hose. I love the stuff. I started using it on my Turbo Buicks years ago and never found anything better since. I would recomend it to anyone.
