Using Marine PRO in car fuel? [SOLVED] Asked by Chris L. In North Carolina Is Marine PRO safe for oxygen sensors and catalytic converters if it was used in passenger cars?
Hi Chris. Marine PRO would be safe to use in any engine fuel. Like any Sea Foam treatment, would not affect O2 sensors or a catalytic converter.
What about in a diesel engine?
Hi Austin. If you mean using in marine diesel fuel or oil, yes.
