We Tested 87, 91 & 93 Octane In The Same Lexus — One Clear Winner!

We tested 87, 91, and 93 octane in the same 2015 Lexus RX 350 over three months under identical driving conditions and the results were shocking. The jump from 87 to 91 octane delivered nearly 2 MPG better fuel economy, 23 knock events dropped to just 3, and acceleration improved noticeably, all for almost the same yearly fuel cost once you account for the efficiency gains. But going from 91 to 93 made almost no difference at all. If you own a Lexus and are still guessing at the pump, this video gives you the exact data you need to make the right call and potentially save hundreds of dollars a year without sacrificing engine health. ► SUBSCRIBE:    / @everythinglexus   #LexusMaintenance #LexusMechanic #LexusCare #LexusOwners Ready to get the most out of your Lexus?
