$400 ethanol tester vs. the $15 Amazon special. 😅

I’ve tested E85 with the cheap graduated tubes for years, but after hearing enough people swear by the Spool Performance Handheld Ethanol Analyzer, I finally decided to see what the hype is about. Spool Performance

This thing uses a real sensor and Bluetooth app to give instant ethanol readings instead of the old water-and-shake method. Is it 26 times better than a test tube? We’re about to find out.

For anyone running boosted cars on ethanol, knowing whether you’re getting E60, E70, or true E85 can be the difference between making power and making expensive noises.

Have you used one of these before? Worth $400 or overkill?
