## What is a 50/1 mix for a gallon?

You want to mix 2.6 ounces of oil to one gallon of gasoline for a 50:1 mixture.

## How many ounces is a 50 to 1 ratio?

For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas. For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas.

**What is a 50 to 1 mixture ratio?**

For example, 50:1 means 50 parts gas to 1 part oil.

**How much oil do I need to mix 50/1 gas with 5 gallons?**

For 5 gallons of gas, with a 50:1 ratio, the amount of oil required is 12.8 US ounces (100 ml). Experts agree that it is better to err toward the side of too much oil, rather than not enough. Typical break in period ratios are about twice the normal; 50:1 is generally 25:1 during break in.

### What is the best oil to gas ratio for 2 stroke outboards?

For 2-Stroke outboards that require a 50:1 premix of oil/gas we’ve put together the following chart to simplify the calculations. Use ONLY 2-stroke outboard motor oil with an NMMA (National Marine Manufacturer’s Assoc.) certified rating of TCW3. Never use automobile motor oil in your 2-stroke outboard!

### How do you premix 2 stroke fuel?

Use a 40:1 two-cycle oil mix ratio. One gallon of gasoline combined with 3.2 oz of two-cycle engine oil. Unsure of the age of your equipment? Use the 40:1 mixture.

**How many ounces is 1 gallon of gas?**

#### How much 2-cycle oil do you put in a gallon of gas?

3.2 fluid ounces

If you have to prepare a mixture of 50:1 ratio then 2.6 fluid ounces of oil is used for each gallon of gas. If the ratio is 40:1, then the required amount of oil is 3.2 fluid ounces per gallon of gas. For the ratio of 32:1, you have to use 4 fluid ounces per gallon.

#### What happens if you put too much oil in a 2-stroke?

Well, if there is too much oil in your two-stroke outboard motor, what happens is that it will end up gumming up the plugs because of the higher consistency of oil. When that happens, the boat’s engine will produce a lot more smoke than it usually does as it burns the excess oil off.
