Yes I am confident, and yes I diluted my RO and used it that way. Worked fine.
Sounds like you'll eventually need to Leatherique your seats. Start with one bottle...you never know, you may not need as much.
Most seats that old and in that condition don't just need conditioning, they need deep cleaning within the leather. Leatherique accomplishes that by dissolving and displacing the muck to the surface.
All other cleaners clean the surface, which is ok if you clean your leather regularly from new.
