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....
