On 6 tanks of fuel in the Hyundai (before I replaced it) I dropped from 11-ish to 10-ish. The first tank made little difference. mid-way through the second tank I noticed it. By the third tank it was fairly consistent.
But I didn't do the A-B-A testing. Mostly because I am lazy.
If I see a consistent change on the F150, I'll do the testing. More people likely interested in a 2018 F150 test than in a 2007 Hyundai SUV test
