Using Sea Foam in my boat’s Volvo Penta V8 engine oil [SOLVED]

I have a Volvo Penta V8 in my boat. I just changed the oil using 25w40 synthetic blended oil. Is it effective to use Sea Foam in the crankcase at this time?

Hi Kieran. Yes, you can add Sea Foam to any 4-stroke engine oil at any time during the interval. No worries!
