Would RecommendGet this about 6 months ago. Went to town on my sons 79 F250 project. I don't know how many different times I have used this on the engine, stuck bolts, 45 years of RUST on the frame. To many to count.

Worlds greatest
Would RecommendI had a lot of bolts to remove and it was being hard to do i grabbed my buddys kroil and put a few drops on each one and went to lunch. After an hour or so i tried the rusty bolt removal again and it was like they werent even tight at all. So, i went and got me a can of kroil and i’ve been using it ever since that day. That was over 20 years ago. I tell everyone, “you need kroil in your life” if i could afford it, i would hand out samples just to show its incredible abilities

A good start.
Would RecommendWhen I first started buying Kroil I bought it at trade shows in this can. I have since used it on nearly everything. This is amazing stuff.

Amazing for auto-repair
I used this on my 2012 volkswagen's ac compressor and the alternator.This is a great product that helped greatly in the repair, could not recommend more for any type of auto-repair.

Above and beyond
Would RecommendKroil has more than lived up to it's reputation as a penetrating oil. Most of the competition doesn't even come close in performances and the results thereof. Cannot recommend Kroil enough for just about any lubricant application, land, sea, and air.

Simply the best
Would RecommendThe best tool in my tool box! Kroil has never let me down.

Great features!
Would RecommendWorks great for everything I need. Small applicator allows me to apply where I need it and not just glaze everything like a spray usually does

An inherited can
Would RecommendWhen Dad died, I went thru his tools and found a can of Kroil..not a full can so I knew he'd been using it. I brought it home and although it took a long time, a little goes a long way, I bought an aerosol and another can. I lent the aerosol to a man who rebuilds pool pump motors...I never got that one back, but that's OK, he's a friend and an old guy. I use the Kroil in my can on my firearms and on the carburetors that I rebuild in my 'cottage industry' It's running a little low so I though I'd...

The best
[This review was collected as part of a promotion.] 3rd generation user. Nothing compares. But the spray can loose propellant so ya cant go wrong with the drip cans!
From kroil
Great for guns
Would RecommendI have been using the original version for years in.my gun cleaning process. After removing powder residue use a wet patch with Kroil and let soak for a few minutes then brush out. Follow up with another dry patch.works great

Amazing penetration!
Would Recommend[This review was collected as part of a promotion.] i bought this about a year ago and I'm extremely satisfied
From kroil
Works where others simply do not.
Would RecommendI’ve worked in an industrial setting for years and have seen oil work where others don’t on parts that see high heat, vibration, and torque. Consider it recommended.
From kroil
great product
Would RecommendThis is my go to penetrant. I've tried other brands but Kroil has stood the test of time.
From kroil
If I'm going to smell like oil it has to be Kroil
Would RecommendI've used Kroil aerosol products for years and loved the results, but never used the drip bottles. Before cleaning up a set of pliers my father carried on his side for 6 years in the Navy I wanted to ensure the patina remained. Kroil worked better than expected and the pliers went from frozen to free in about 24 hours.
From kroil
Works Great
Would RecommendUsed this for decades, best penetrating oil out there
From kroil
I can does it all
Would RecommendYou just can’t kill this stuff. Works on firearms like no other and not to mention other things around the house and garage.
