I think my gas is clean from my boat but was wondering if an additive put in two fillups ago might give my emissions some issues on my 07 Subaru. ? I bought my boat used and the previous owned used Yamaha ring clean regularly. So two fillups ago (Probably $200 of fuel) has been run through the system with just Premium with no Ethanol. Anyone know much about RingClean?Hopefully the boat is to be stored by Sunday. My plan is to have new gas with Stabil and run the boat out gas as I am fogging it.
