Does synthetic oil reduce mileage?

A synthetic oil is exactly that, it has all of the properties of a mineral oil, but manufactured to reach new levels in flow, viscosity, efficiency, performance and last but not least, mileage. It effectively does the same thing as a blend or mineral oil, but better in every way.

Can you put conventional oil in a synthetic engine?

In the end, conventional and synthetic oils are completely compatible. However while you can safely mix synthetic and conventional oils, you're diluting the performance of the synthetic oil.
