Question

On a mercury 15 hp what is the ratio of gas and oil

Answer 1

50 to 1

15.36 oz of oil to 6 gallons of gas

Answer 2

typically io use 8 oz. of 2 cycle oil for each gallon

Answer 3

8 oz per gallon is 16:1 which is way toooo much oil. 50:1 is the right mixture. 16:1 will run the engine way to lean on gas and burn holes in the pistons.

Answer 4

50:1

for all outboards this is a great mix

A friend of mine has a shop and he runs this mix in all two strokes that leave his shop, weedwhackers, chainsaws, boat motors, that all do just fine.

Just make sure the oil is rated either TC for two stroke and TC-W for water cooled two stroke.
