Ever go to the store and see a can of octane booster on the shelf. I know I have and I’ve even been known to purchase a can from time to time. In the back of my mind though I always wondered if it actually did anything, either good or bad. Some people say that if your running low-octane fuel in a higher compression engine that this stuff will in fact raise your octane level, while others say they’ve felt massive gains in performance. For the most part though I think we want to feel justified in our minds because we just spent $8 on a can of the stuff. I recently found this video done by the UK’s Fifth Gear TV show where they put four of the major brands of octane/power boosters to the test and I must say that the results surprised even me.
