Just had a juke back at the mot results to 2015,, 0.010 0.050 0.010 0.030 and 0.030,, normally I would have done the engine service before the test but not since 2015... normally about june or july, I am wondering if the fluctuations in the readings are an indication of the engines health or will a service before the next test bring it back down to 0.010.
