At the shop for loosening things we used a liquid called Kroil for it and we got it by the gallon and Cat even sold it years ago but possibly an automotive or truck parts supply store might have it too.It was a deep red type oily liquid and I never used any type of the penetrating oil that worked as good as it would.Make sure you ask for Kroil.
54d2,
Kroil is the ticket, Airkroil is the spray can, Kroil is the liquid can.
We use this exclusively for lubricating and loosening bolts and... stuck engines. I learned about this product years ago at the refineries I worked at. Every refinery I worked at used this product for various applications.

I've used ATF. It works pretty well.
I have a stuck 15 and kroil hasn't impressed me yet I still think Gibbs is better and a better bargain. Just my 2 cents. Jason
There is a Gibbs fan. You got it Jason I bought my first can about four years ago in PA. I use it all the time worked so well I bought 6 cases at the Rought and Tumble show last year. A friend of mine is realtated to the fellow that is there every year selling Gibbs😊
ran ads for Gibb and I think John Deeres Green magazine did too. Someday I'll try it when I get a chance to pick up a can.
have you tried PB blaster, we work with stuck or rusty bolts all the time and this has out preformed all of the others on the market.
I suppose there are maybe better or just as good of new oils today as I,ve been retired from Cat dealer since 1991 and not in or up to lots of new things that have come out since then.It,s good to know of these newer or better items on the market today.
Sj I don't know that gibbs is better than kroil but for what kroil costs I think gibbs is just fine. I put kroil in a piston about 3 months ago and still haven't had much luck it must really be tight! Jason
