Is anybody running premix, if so what brand and ratio do you use? Does it make the car smoke?

I do. are you also using the stock OMP, or just pre-mix. Make sure it's TCW-3. Doesn't really mattter what brand. I go to boat stores and buy that stuff by the 5 gallon jug and then place into a smaller container for my car. The most common brand seems to be the valvoline stuff. It doesn't make my car smoke any more than before. Except at WOT, but that's also more fuel. TCW-3 is design to be real clean burning and completely ashless i believe.

I'll still be using half of the stock oil metering pump, '86 engine 12A front cover and omp = only two line instead of four, just thought premix would be insurance until I rebuild in march
