1st. test results.
I was not correct when stating my mpg. as 16.5 I went back through 9 mos. for records and my average was 15.5mpg.
After running the Ethos in one tank of fuel and in the engine oil. The mpg in country driving was 16.7.
I have now change the oil and put the Ethos in a new tank of fuel and the oil. I will have another milleage check this friday. Cheers
