Bwalker a few questions. I agree the the oils with less viscosity as 2r,k2,710 ,lucas r gonna be more efficient in the combustion process and still offer the same protection in our application. Also think the right builup is indication of proper tuning and correct oil for our application. Will the lower viscosity oils at 32to1 offer the same protection in the bottomend as the ester oils at 32to1 and what are the negatives in the topend using the ester oils at 32to1 in the topend other than impeding the combustion process? Thanks
