Do not use oils for leather / urathane surface care
Proper Leather Care
The interior environment of an automobile can be extremely demanding on any material used. Temperatures range from hot dry summer days, to freezing nights. Both high and low humidity, even air conditioning that cools, but also dries. Leather's greatest enemies are; sun, heat, body oils and ultra violet radiation (UVR), which dries the hide, fades the colour by bleaching, and can cause the leather to fail by drying out the fibres causing the polyurethane and / or the hide to crack.
Many leather products market themselves on how they feed or condition leather. In fact your car's leather seats are first coated with a very fine emulsion (pigmentation) to give them the desired colour and then a clear urethane coating. So for best longevity you should be keeping that coating clean, hydrated and as well protected as possible.
These same companies would also have you believe you should feed your car's urethane leather finish with olive, cantaloupe, sunflower and coconut oils, lanolin or coat it with wax. These products even if they were necessary cannot permeate the urethane coating, they will only attract dust. Unless you brought a specific premium natural leather upholstery package - you are dealing with the finished protective coating and not with the leather hide itself.
