It’s a tool that’s used to calculate how much oil is required to operate a particular type of two-stroke engine. It can calculate both the pre-mix and post-mixed fuel amounts.

The way that this app works is that you have to first set the amount of fuel that you have in your tank. Then, you’ll have to select the ratio of fuel to oil that you want to create. Once you have done that, you’ll have to enter the amount of oil that you need to operate the engine.

The reason why this app is better than other similar apps is that it is very easy to use and it gives you a lot of flexibility. You can also choose between US and metric units.

This app is also used by many other two-stroke applications, such as snowmobiles, motorcycles, scooters, boats, golf carts, and many other small engine applications.
