Not sure what oil to run in the freshly built formula atlantic spec 3k race engine of my old mans, is just being run in atm, from memory its 12.5:1 comp ratio, has big cam, 45mm webers etc etc a long list of work done, is worked to its limit.
Would like some advice on oil from people who have owned heavily modified K motors as i am more familiar with turbo import engines, i want to make sure it is the most ideal oil for it as the bottom end rebuild on this was far from cheap.
discuss please :) cheers
