A. It has been reported that higher biodiesel blends above 5% may increase the rate of oil oxidation and fuel dilution. This, however, is still under further review. To be on the safe side, we recommend using higher performance heavy-duty engine oils, especially when operating in severe conditions or when employing extended drain intervals. It is also recommended to utilize an oil analysis program to monitor oil condition.
