Excellent product Great service.

Great service. Thanks.

The product works as advertised, great for loosening stuck bolts and things like that. Fast shipping and a fair price from Aircraft Spruce Canada. Im glad I found a Canadian shop to get this from, and the price was actually better than that well known online retailer of everything...

I have purchased this product for years. its amazing, I used it on Catapillar D-2 & D-4 crawler tractors, & several JOHNDEERE, OLIVER, & CASE Discing equipment, and have never been let down. if you use it right it works great! When you have old Caterpillar D-2- 5U & D-4-7U , series tractors, it helps loosing nuts, bolts, radiator pulleys, even frozen pistons,rings, starter motors. I have even used this product on old cars & trucks, boats, & aircraft engines, for pickling, it works great!

I had a blade on my mower deck that was impossible to break the nut loose even after heating with a torch and a 30 inch breaker bar. I tried PB Blaster and every other penetrating oil I had with no success. My last resort was Kroil oil let it soak for about an hour. I went back and put my impact wrench on which I had tried many times before with no success and to my surprise it came right off. That is exactly why I ordered another can of Kroil Oil!!!

Highly recommend ! Will definitely impress you !

My order was processed all in good order. Kroil is very good product compared to other oils. Not hard to use for not real offense odor and has many uses.

Works great on rusted nuts and bolts. Frees stuck cables.

Bought this for my son, who is restoring a 67 Impala... hoping it will loosen a few seized parts. They have been soaking for a few days, waiting patiently for this to work, as I’ve read it’s the best.

Great for cleaning firearms. Great service from vendor as well

I cannot rate this product properly as I only used it once and it didnt work for me. I tried to free a seized choke tube from a shotgun, left it soaking in it for a week and it didnt budge. Had to have a gunsmith use a pipe wrench on it and ruined the choke.

Ron S Verified Purchase

Aerokroil 8 Oz Can

Im disappointed in this product. I am attempting to remove a stuck bearing which had been exposed to excessive moisture this product had been highly recommended to me by other mechanics yet after a week of allowing this oil to soak into the bearing it still wont budge. I should have followed my gut instinct and used a torch. Im really disappointed because I spent a good deal of money to get this product and like millions of others, my funds are very limited at this time. Cannot in good conscience recommend this product.
