Gasoline:Oil Mixture Measuring Cup - 50:1 and oz/ml

NOTE : Addition on Sept. 5, 2024; two variants added :

• Measure06C - label holder on outside of cup
• Measure06D - plain cup, no label holder

This measuring cup was made specifically for my chainsaw, which requires a gasoline:oil mixture of 50:1. However, I also wanted to make it more generally useful, as well as customizable for other required fuel mixtures. For this reason I designed the cup with removable volume labels.

If you need a 50:1 fuel mix measured in gallons as I do, then simply insert the appropriate label. The marker lines show how much oil to use for either 1 or 2 gallons of gas.

If you need a different ratio, or are working with liters instead of gallons, then you can insert the “general” label. I suggest marking your required oil volume with a marker pen before inserting the label, for ease of use.
