I have diesel fuel, Break fluid and kerosene. Sometimes I even mix them. All have worked just depends how bad it is stuck. Can you look into the cylinders with a bore scope and see how bad it is?

I had one ever sit for a very long time and was seized up. I poured marvel mystery oil in it and let it sit a week. I had it running in a week and it actually sounds and runs good.

You could get some wd40 penetrating spray it even has a straw to get it all around the bore.
