Importance of Octane Levels
Probably one of the most important things for us future Ranger Raptor owners will be making sure we meet or exceed the Octane rating our Raptors call for, much like what F-150 Raptor guys have been recommended. Its been reported that after running 87 Octane all the way to empty and then refilling on the recommended rating, the difference was night and day. Aside from the difference in performance, I don't know what negative effect this can have on the engine and related components but if you can only find 87 Octane, stocking up on Octane Booster should insure you don't go through this experience.
In addition, even if you find 93 or better yet E85...still throw in the Octane Booster, you'll be in for a treat
