If you read the attached pdf you will see that this product only contains:Pale oil, naphtha, and IPA [isopropyl alcohol]. No detergents pretty useless [on that front] but it will do no harm. Note [from MSDS] that each version contains the same 3 ingredents just the % are juggled for different applications.
Similar to Marvel Mystery Oil.
PALE OILS are light coloured, non-staining naphthenic oils refined from specially selected wax-free crude through the use of severe hydrogenation. This process produces oils of excellent initial colour and colour stability while maintaining their compatibility with most synthetic elastomers.
The above could best be described as the semi synthetic oil found in oil of that genre.............a hydrogenated motor oil used to carry the two solvents

You could buy a quality motor oil and mix in naptha and IPA and create the same product for less.
Never researched this product before but it is all explained in the MSDS sheet.
