Greetings,

As for oil, I still don't know what's best.  IF we were using a 2-stroke
engine, it would make sense to use the best 2-stroke oil.  Since we aren't,
we can only look to Mazda for guidance.  Of course they used regular oil
from the sump, which we strongly suspect wasn't their first choice.  Does
anyone know what they run in their race engines?  

Hey Lynn, or Leon, what do you folks in the racing world use?

Thanks,
Rusty (keeping FedEx in business a couple fittings and sensors at a time)
