I was considering a warm water/mineral oil mix to lubricate 15 year old seals. Is this viable and will it help keep the "dry" pumped waste water from leaking back.
Lubrication for head pump

Noooo.,...
First of all, there isn't enough left of 15 year old seals to be worth lubricating. But even if there were, a mixture of warm water and mineral oil will last MAYBE two flushes. Mineral oil alone might last half a dozen flushes at most. However, pump seals have nothing to do with whether waste runs back into the bowl from the head discharge hose...That's due to two things: 1. you aren't flushing long enough to push the bowl contents all the way to the tank (or over the top of any "hill" in the line), and 2. a joker valve in the head discharge that's been totally worn out for at least 12 of the last 15 years since it was changed. You're not gonna get out of this by just pouring something down the toilet...it's gonna require some actual work. Your toilet isn't just WAY overdue for new joker valve, it's been overdue for complete rebuild almost that long...and after 15 years, it's doubtful that will help much. You may be better off just replacing it. And then flushing it longer.

Replace the toilet
Hello, If, after 15 years, you need to work on the toilet, you are better off just removing it and throwing it away. If you do work on it, you are going to have to change EVERY seal, and odds are that when you put it back together something will leak. I just replaced the toilet in my 1986 Newport 28. I first tried to rebuild it (I found a rebuild kit in one of the storage compartments). After replacing all the seals in the kit (and yes, it was pretty gross taking it apart), I had a bad leak near the bottom. I tried tightening one of the screws, and the bottom mount cracked. So I needed a new toilet anyway. The good news is you can get a cheap toiley for $150 of so, or a good toilet for $200 or so (both basic manual units). To install the toilet took about 30 minutes. Remove the water intake line (1 minute), the head exhaust line (1 minute, be sure to flush it a lot first), then 4 bolts that head the toilet down. Remove old toilet and throw in garbage. The new toilet didn't have the same bolt pattern, so I still have to do that, but it should be pretty easy to make new holes (I need to make an access panel, that will be done this weekend). Good luck, Barry
