Thank You for Your QuestionCustomer


The fuel to oil ratio is 50 to 1



This equates to 1 pint two cycle outboard oil to 6 gallons of fuel


1 Qt to 12 gallons


1 Gallon to 48 gallons and so on


Not just any oil will do, be sure to use a good quality Two Cycle "Outboard" Engine Oil...


Jet ski oil will foul a outboard and the extra expense is unfounded....
