Mixing Synthetic and Conventional Motor Oils
Can you ever blend synthetic oils and conventional oils? If so, what is the ratio?
-- Julie Patten, Des Moines, IA
Yes, synthetic oils can be blended with conventional oils. Several companies, including ExxonMobil, market synthetic blends which are a combination of synthetic and conventional oils. In the case of ExxonMobil, the ratio of synthetic to conventional oil in these products is considered proprietary information.
