20W40, 20W50 and Heat Range 22 or Heat Range 7.....

Got the Torco SR1 with a special mixture of 2 bottles of 20W50 and 3 bottles of 20W40.....

Also included now is the Denso Iridium Plug with Heat Range 22 with a gap of 0.4mm.....

Hopefully they blend well together and by this I meant the Torcos.....

So far no issues with starting despite the original Heat Range for RB25DET is a 6 for NGK and 20 for DENSO.....well, I may be wrong and please correct me.....
