I use a 1966 Land-Rover with a Ford Essex V6 engine conversion (lovely old thing!) to do local trips towing a powerboat, carrying canoes and windsurfers etc. The last garage selling LRP locally is ceasing to do so shortly, leaving me with a problem.
I suspect that unleaded would damage this engine in time, which leaves some form of additive as the only practicable option. Driving any distance to get LRP elsewhere - even if available - isn't that practical at 13 mpg....
When I looked at this some years ago, there were a number of additives available of presumably variable quality and effect (and cost!) and I guess that time and experience has shown which work, and which don't.
Any guidance on what to use, where it can be bought, and at what cost would be much appreciated.
Thank you!

(Perhaps I should add that I am aware that having the heads removed and hardened valve seats fitted is an option, but I guess that this would cost in the hundreds to have done, as it is outside my skill remit. As the vehicle only covers around 1500 miles a year, the cost/reward relationship for this isn't great).
