I used to run Bel-Ray and Spectro but I switched to Maxima Castor 927 and I like it. I'm definitely going to stick with the Castor 927. I premix at 32:1 with race gas.
The only thing to note about Castor 927 is that it can separate in the extreme cold with certain types of race gas so you need to be careful with it in the colder climates. To be safe, I have been cutting my race fuel 50/50 with 93 octane pump gas in the winter, which should reduce the possibility of separation.
In terms of the tranny, I use Bel-Ray Gearsaver but I have also used Pro Honda HP Transmission Oil in the past.
