# How do you mix gas on a Mercury outboard motor?

Any motor built after around 1965 will run just fine on 50:1 (20 ml oil on 1 Liter or 2.5 ounces of oil for each gallon of gas) mix. For your 2-stroke outboard, be sure and use only 2-cycle outboard oil, with an NMMA (National Marine Manufacturers Association) certified rating of TCW3.

Similarly, what is the oil to gas ratio for a 2 stroke outboard motor? 50:1

In this way, what is the mix ratio for outboard motors?

How do you calculate the gas to oil mixture for a two-stroke boat motor in the United States? For a 50:1 ratio each gallon of gas requires 2.6 oz of two-stroke engine oil. For a 40:1 ratio each 1 gallon (gal) of gas requires 3.2 ounces (oz) of oil.

What is the ratio of gas to oil for an outboard motor?

How do you calculate the gas to oil mixture for a two-stroke boat motor in the United States? For a 50:1 ratio each gallon of gas requires 2.6 oz of two-stroke engine oil. For a 40:1 ratio each 1 gallon (gal) of gas requires 3.2 ounces (oz) of oil.

### Should I run premium gas in my outboard?

Putting lower-octane gas in a high-performance motor rated for premium gasoline may cause that motor to knock. But putting high-octane gas in a regular outboard won’t do a thing except lighten your wallet. It will not give you any more power.

### Is there a difference between marine gas and regular gas?

The only difference between on the water gas and station gas is the price. Boats in the water are held hostage so marinas take advantage of them.

### What kind of gas does a Mercury 4 stroke outboard take?

Specifications – 75 HP / kW 75 / 56 Recommended fuel Unleaded Regular 87 Octane Minimum (R+M/2) or 90 RON 10% Ethanol Maximum Recommended oil Mercury FourStroke Oil 10W-30 Engine protection operator warning system SmartCraft Engine Guardian Compatible with SmartCraft digital technology Yes

### What is a 50 to 1 gas oil mixture?

You want to mix 2.6 ounces of oil to one gallon of gasoline for a 50:1 mixture. If you’re mixing up two gallons of gasoline you will have to mix 5.2 ounces of oil to two gallons of gasoline for a 50:1 mixture.

### What is the ratio for 2 stroke fuel mix?

Mixing Ratio (Gas:Oil) Volume of Gasoline Volume of 2-Cycle Oil 32:1 1 US gal. (128 oz) 4 oz. 40:1 1 US gal. (128 oz) 3.2 oz. 50:1 1 US gal. (128 oz) 2.6 oz. 32:1 1 liter 31.25 ml

### Do 2 stroke outboards have engine oil?

Two-stroke motors require a mixture of oil and gas to lubricate all of the moving parts, which can be expensive and somewhat difficult to formulate. Additionally, two-stroke engines are less fuel-efficient, get fewer miles per gallon and produce more emissions than four-stroke outboard motors.

### Can you use any 2 stroke oil outboard engine?

Two-stroke outboards require oil that meets the TC-W standard, which indicates a marine oil designed for a two-stroke engine. Again, consult the owner’s manual for specific two-stroke oil requirements.

### How do you calculate fuel mixture ratio?

Divide the ounces of gas by the gas-to-oil ratio number in your owner’s manual and round the answer to the nearest whole or half number. For example, a 40:1 ratio is 128 ounces divided by 40, which is 3.2, rounded to 3 ounces, needed of 2-cycle oil for 1 gallon of gas.

### How do you service a 2 stroke outboard motor?

How to service a 2-stroke outboard engine Do it yourself! This step-by-step guide takes you through a service of a small 2-stroke outboard. 1: Drain the old fuel. Check the spark plug. Check the recoil starter. Remove, strip and clean the carburettor. The lower leg. Remove the gearbox to check the water pump. On smaller engines with only one gearâ€¦
