you just have to run a oil that will mix with meth. Like 927, or Supertechniplate. you do not need to change the oil after every run. You will have to run a B9 series plug. other then that just purge it and run the oil a little richer then gas. I ran gas 36:1 and alky 32:1. you can purge it with just pump gas and yamalube rahter then buying race gas and supertechniplate. go to napa and you can buy a universal radiator overflow and make it into a purge bottle.
