Rated 4.3 out of 5 by 18 reviewers.
Rated 4 out of 5 by Always useful, and smelly. I have used this stuff for years. It works well with adequate hose pressure or power washer. I wish it smelled better as the odor will linger for a day or so. Kind of an oily / diesel smell. July 31, 2015

Rated 5 out of 5 by Good Gunk stuff.... Gunk engine de-greaser works good on the oily gunk, but it's best to let it sit on the surface a while to sink in then rinse and you have a nice, clean engine... July 15, 2015

Rated 5 out of 5 by Clean!!! Got my engine Gunk off. I purchased a 1987 pontiac. It looks like it never had the engine cleaned. So after 30 plus years there was a lot of grime. With a strong hose and some hard brushes I got the crud off and it looks brand new. January 17, 2015

Rated 2 out of 5 by Not as good as it used to be. 10 - 15 years ago it was better -- but with all the EPA standards - It's now so diluted it barely works. September 10, 2014
