Got a 79 Johnson 140 ,mixing oil with the fuel ,is it ok mix additives to the fuel ,or is it needed ?
Sea Foam is up to 20 percent isopropyl alcohol....Make sure you use a 100% petroleum product like Sea Foam which I find to work very well.
Don't use anything with alcohol!!!!!!! Same as ethanol in gas....bad thing
There is no need for 92 octane, 87 octane is all that is needed.
I like to run either Sea Foam or Carbon Guard with every tank, your motor will thank you. A tank doesnt last me very long in the summer, so I only add the Stabil on the last tank of the year.
