I have 8 hours on a new IO-360-M1B and the engine is not burning much (or any ) oil. Seems like it burned maybe 1/4 qt or so the first couple hours but has not burned any since. Should it be burning more at this point? CHT's got close to 400*F first couple of hours but now are around 350-360*F. It's ready for an oil change so just wondering if I should stay with the straight mineral oil until the next change? Most of the flights have been close to an hour with the longest being 1.5.
Thanks for your input.
