FAR FROM "giving up" on RL, I just wish that they used this new sulphur-free ZP, instead of the old tried and true ZDDP.
I would not trade this stuff away for a Grp. 3 oil NO MATTER WHAT the base oil, OR the net VI happened to be.
But, my catcons sometimes have that "just lit match", rotten eggish sulphur smell, and I don't know if it is from running too rich on our high-sulphur U.S. fuels during W.O.T., or if it is
a little of the RL getting by my rings and valve seals into the combustion chamber.
Either way, the less sulfur the better, and I will have to look into a 'lean it out' type tune I guess.
