I have an ongoing discussion over 87, 89, HTest gas and my knowledge is that 87 is a dirty gas that can clog up your engine, that 89 is a clean more economical gas that will not clog as bad and that High test is something to switch on and off of monthly or every few fill ups or so and stay away from 87 totally to keep your engine cleaner
What do you all think or know? Thanks
have the same problem?
