As the recommendations are starting to fly I will weigh in briefly as there are a number of issues at play. There is no one perfect leather care product. The reason is that there are numerous ways to tan, color and even paint leather. I personally like Neats Foot oil as this is a natural fat rendered from cows ankles that is liquid at room temperature. Now, this fat is not cheap, so it is often extended with other chemicals. Getting a straight list of ingredients is a problem, save for in the USA there are Material Safety Data Sheets that upon request Must be provided, those sheets will provide the list of ingredients, but not in percentage. So, Compound, can mean anything. Natural Hydrocarbons is another nice term for petro-chemicals, crude oil and comes from the ground remember, from plants and dinos...
I don't like Lexol. At least on car interior leather, which now is almost all painted, with Vinyl! On a bike painted leather shows up on toe straps, save for most Binda's which are just dyed. Only general production vehicle with just dyed leather is the Kings Ranch trim package Ford F series truck.
I do not like products with silicone in them. Period.
I will be testing Leatherique, problem I have had is getting an MSDS report before I get the product. Only seller who has played that game so far.
2 cents worth for now. But I will advise I work with leather every work day.
