Comments on Octane and Ethanol Calculator for Android

★★★★★ Marshall Loewenstein · Jan 13, 2026

Unique capability that doesn't really exist anywhere to get a precise octane mixture. Tests spot on for Ethanol with my inline sensor. Obviously, can't test for the octane calculations as that takes a special lab and $$$.

★★★★★ James M · Feb 17, 2026

Awesome app to quickly figure out e85 blend ratios with gasoline as well as octane with fuel blends.

★★★★★ Jefe R · Jul 6, 2026

Very helpful on helping me figure out proper octane blend for my tuned car.

★☆☆☆☆ Vincent Tyler · Apr 15, 2026

Devs don't tell you they want $7.00 a month for basic gas calculations.

★☆☆☆☆ Dan Nesthus · Nov 9, 2025

App requires a $6.99 Subscription before you can even try it out. It may work, but I'm not willing to buy it when there are free apps and websites.
