Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

How do I figure 50 to 1 using a 5 gallon liquid container? Oil to gas.

For ounces of 2-cycle oil to add to the gasoline: Gallons * 128 / 50 = 12.8 oz

There are 128 oz per 1 gallon
50:1 ratio = 50 parts gas:1 part oil, so divide by 50

FWIW, when mixing oil with gas for 2-cycle engines, it doesn't have to be exact but it should be close.

This formula works for any gas:oil ratio. If the mixture was 30:1, it would be: gallons * 128 / 30 = 21.3 oz
